+EXECUTIVE SUMMARY ON GPU USAGE (SEE ALSO SCRYPT-README FOR SCRYPT MINING):
+
+Single pool, regular desktop:
+
+cgminer -o http://pool:port -u username -p password
+
+By default if you have configured your system properly, cgminer will mine on
+ALL GPUs, but in "dynamic" mode which is designed to keep your system usable
+and sacrifice some mining performance.
+
+Single pool, dedicated miner:
+
+cgminer -o http://pool:port -u username -p password -I 9
+
+Single pool, first card regular desktop, 3 other dedicated cards:
+
+cgminer -o http://pool:port -u username -p password -I d,9,9,9
+
+Multiple pool, dedicated miner:
+
+cgminer -o http://pool1:port -u pool1username -p pool1password -o http://pool2:port -u pool2usernmae -p pool2password -I 9
+
+Add overclocking settings, GPU and fan control for all cards:
+
+cgminer -o http://pool:port -u username -p password -I 9 --auto-fan --auto-gpu --gpu-engine 750-950 --gpu-memclock 300
+
+Add overclocking settings, GPU and fan control with different engine settings for 4 cards:
+
+cgminer -o http://pool:port -u username -p password -I 9 --auto-fan --auto-gpu --gpu-engine 750-950,945,700-930,960 --gpu-memclock 300
+
+READ WARNINGS AND DOCUMENTATION BELOW ABOUT OVERCLOCKING
+
+To configure multiple displays on linux you need to configure your Xorg cleanly
+to use them all:
+
+sudo aticonfig --adapter=all -f --initial
+
+On Linux you virtually always need to export your display settings before
+starting to get all the cards recognised and/or temperature+clocking working:
+
+export DISPLAY=:0

+BUILDING FOR GPU SUPPORT:
+
+	To build with GPU mining support:
+	Install AMD APP sdk, ideal version (see FAQ!) - no official place to
+	install it so just keep track of where it is if you're not installing
+	the include files and library files into the system directory.
+	(Do NOT install the ati amd sdk if you are on nvidia.)
+	To build with GPU monitoring & clocking support:
+	Extract the AMD ADL SDK, latest version - there is also no official
+	place for these files. Copy all the *.h files in the "include"
+	directory into cgminer's ADL_SDK directory.
+
+The easiest way to install the ATI AMD SPP sdk on linux is to actually put it
+into a system location. Then building will be simpler. Download the correct
+version for either 32 bit or 64 bit from here:
+	http://developer.amd.com/tools/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/
+
+The best version for Radeon 5xxx and 6xxx is v2.5, while 7xxx cards need
+v2.6 or later, 2.7 seems the best.
+
+For versions 2.4 or earlier you will need to manually install them:
+This will give you a file with a name like:
+ AMD-APP-SDK-v2.4-lnx64.tgz (64-bit)
+or
+ AMD-APP-SDK-v2.4-lnx32.tgz (32-bit)
+
+Then:
+
+sudo su
+cd /opt
+tar xf /path/to/AMD-APP-SDK-v2.4-lnx##.tgz
+cd /
+tar xf /opt/AMD-APP-SDK-v2.4-lnx##/icd-registration.tgz
+ln -s /opt/AMD-APP-SDK-v2.4-lnx##/include/CL /usr/include
+ln -s /opt/AMD-APP-SDK-v2.4-lnx##/lib/x86_64/* /usr/lib/
+ldconfig
+
+Where ## is 32 or 64, depending on the bitness of the SDK you downloaded.
+If you are on 32 bit, x86_64 in the 2nd last line should be x86
+
+Basic *nix build instructions:
+	CFLAGS="-O2 -Wall -march=native" ./configure <options>
+	or if you haven't installed the AMD files in system locations:
+	CFLAGS="-O2 -Wall -march=native -I<path to AMD APP include>" LDFLAGS="-L<path to AMD APP lib/x86_64> ./configure <options>
+	make
+
+	If it finds the opencl files it will inform you with
+	"OpenCL: FOUND. GPU mining support enabled."

+INTENSITY INFORMATION:
+
+Intensity correlates with the size of work being submitted at any one time to
+a GPU. The higher the number the larger the size of work. Generally speaking
+finding an optimal value rather than the highest value is the correct approach
+as hash rate rises up to a point with higher intensities but above that, the
+device may be very slow to return responses, or produce errors.
+
+NOTE: Running BTC intensities above 9 with current hardware is likely to only
+diminish return performance even if the hash rate might appear better. A good
+starting baseline intensity to try on dedicated miners is 9. 11 is the upper
+limit for intensity while BTC mining, if the GPU_USE_SYNC_OBJECTS variable
+is set (see FAQ). The upper limit for sha256 mining is 14 and 20 for scrypt.

+OVERCLOCKING WARNING AND INFORMATION
+
+AS WITH ALL OVERCLOCKING TOOLS YOU ARE ENTIRELY RESPONSIBLE FOR ANY HARM YOU
+MAY CAUSE TO YOUR HARDWARE. OVERCLOCKING CAN INVALIDATE WARRANTIES, DAMAGE
+HARDWARE AND EVEN CAUSE FIRES. THE AUTHOR ASSUMES NO RESPONSIBILITY FOR ANY
+DAMAGE YOU MAY CAUSE OR UNPLANNED CHILDREN THAT MAY OCCUR AS A RESULT.
+
+The GPU monitoring, clocking and fanspeed control incorporated into cgminer
+comes through use of the ATI Display Library. As such, it only supports ATI
+GPUs. Even if ADL support is successfully built into cgminer, unless the card
+and driver supports it, no GPU monitoring/settings will be available.
+
+Cgminer supports initial setting of GPU engine clock speed, memory clock
+speed, voltage, fanspeed, and the undocumented powertune feature of 69x0+ GPUs.
+The setting passed to cgminer is used by all GPUs unless separate values are
+specified. All settings can all be changed within the menu on the fly on a
+per-GPU basis.
+
+For example:
+--gpu-engine 950 --gpu-memclock 825
+
+will try to set all GPU engine clocks to 950 and all memory clocks to 825,
+while:
+--gpu-engine 950,945,930,960 --gpu-memclock 300
+
+will try to set the engine clock of card 0 to 950, 1 to 945, 2 to 930, 3 to
+960 and all memory clocks to 300.
+
+AUTO MODES:
+There are two "auto" modes in cgminer, --auto-fan and --auto-gpu. These can
+be used independently of each other and are complementary. Both auto modes
+are designed to safely change settings while trying to maintain a target
+temperature. By default this is set to 75 degrees C but can be changed with:
+
+--temp-target
+e.g.
+--temp-target 80
+Sets all cards' target temperature to 80 degrees.
+
+--temp-target 75,85
+Sets card 0 target temperature to 75, and card 1 to 85 degrees.
+
+AUTO FAN:
+e.g.
+--auto-fan (implies 85% upper limit)
+--gpu-fan 25-85,65 --auto-fan
+
+Fan control in auto fan works off the theory that the minimum possible fan
+required to maintain an optimal temperature will use less power, make less
+noise, and prolong the life of the fan. In auto-fan mode, the fan speed is
+limited to 85% if the temperature is below "overheat" intentionally, as
+higher fanspeeds on GPUs do not produce signficantly more cooling, yet
+significanly shorten the lifespan of the fans. If temperature reaches the
+overheat value, fanspeed will still be increased to 100%. The overheat value
+is set to 85 degrees by default and can be changed with:
+
+--temp-overheat
+e.g.
+--temp-overheat 75,85
+Sets card 0 overheat threshold to 75 degrees and card 1 to 85.
+
+AUTO GPU:
+e.g.
+--auto-gpu --gpu-engine 750-950
+--auto-gpu --gpu-engine 750-950,945,700-930,960
+
+GPU control in auto gpu tries to maintain as high a clock speed as possible
+while not reaching overheat temperatures. As a lower clock speed limit,
+the auto-gpu mode checks the GPU card's "normal" clock speed and will not go
+below this unless you have manually set a lower speed in the range. Also,
+unless a higher clock speed was specified at startup, it will not raise the
+clockspeed. If the temperature climbs, fanspeed is adjusted and optimised
+before GPU engine clockspeed is adjusted. If fan speed control is not available
+or already optimal, then GPU clock speed is only decreased if it goes over
+the target temperature by the hysteresis amount, which is set to 3 by default
+and can be changed with:
+--temp-hysteresis
+If the temperature drops below the target temperature, and engine clock speed
+is not at the highest level set at startup, cgminer will raise the clock speed.
+If at any time you manually set an even higher clock speed successfully in
+cgminer, it will record this value and use it as its new upper limit (and the
+same for low clock speeds and lower limits). If the temperature goes over the
+cutoff limit (95 degrees by default), cgminer will completely disable the GPU
+from mining and it will not be re-enabled unless manually done so. The cutoff
+temperature can be changed with:
+
+--temp-cutoff
+e.g.
+--temp-cutoff 95,105
+Sets card 0 cutoff temperature to 95 and card 1 to 105.
+
+--gpu-memdiff -125
+This setting will modify the memory speed whenever the GPU clock speed is
+modified by --auto-gpu. In this example, it will set the memory speed to
+be 125 Mhz lower than the GPU speed. This is useful for some cards like the
+6970 which normally don't allow a bigger clock speed difference. The 6970 is
+known to only allow -125, while the 7970 only allows -150.
+
+
+CHANGING SETTINGS:
+When setting values, it is important to realise that even though the driver
+may report the value was changed successfully, and the new card power profile
+information contains the values you set it to, that the card itself may
+refuse to use those settings. As the performance profile changes dynamically,
+querying the "current" value on the card can be wrong as well. So when changing
+values in cgminer, after a pause of 1 second, it will report to you the current
+values where you should check that your change has taken. An example is that
+6970 reference cards will accept low memory values but refuse to actually run
+those lower memory values unless they're within 125 of the engine clock speed.
+In that scenario, they usually set their real speed back to their default.
+
+Cgminer reports the so-called "safe" range of whatever it is you are modifying
+when you ask to modify it on the fly. However, you can change settings to values
+outside this range. Despite this, the card can easily refuse to accept your
+changes, or worse, to accept your changes and then silently ignore them. So
+there is absolutely to know how far to/from where/to it can set things safely or
+otherwise, and there is nothing stopping you from at least trying to set them
+outside this range. Being very conscious of these possible failures is why
+cgminer will report back the current values for you to examine how exactly the
+card has responded. Even within the reported range of accepted values by the
+card, it is very easy to crash just about any card, so it cannot use those
+values to determine what range to set. You have to provide something meaningful
+manually for cgminer to work with through experimentation.
+
+STARTUP / SHUTDOWN:
+When cgminer starts up, it tries to read off the current profile information
+for clock and fan speeds and stores these values. When quitting cgminer, it
+will then try to restore the original values. Changing settings outside of
+cgminer while it's running may be reset to the startup cgminer values when
+cgminer shuts down because of this.
+

+
+GPU DEVICE ISSUES and use of --gpu-map
+
+GPUs mine with OpenCL software via the GPU device driver. This means you need
+to have both an OpenCL SDK installed, and the GPU device driver RUNNING (i.e.
+Xorg up and running configured for all devices that will mine on linux etc.)
+Meanwhile, the hardware monitoring that cgminer offers for AMD devices relies
+on the ATI Display Library (ADL) software to work. OpenCL DOES NOT TALK TO THE
+ADL. There is no 100% reliable way to know that OpenCL devices are identical
+to the ADL devices, as neither give off the same information. cgminer does its
+best to correlate these devices based on the order that OpenCL and ADL numbers
+them. It is possible that this will fail for the following reasons:
+
+1. The device order is listed differently by OpenCL and ADL (rare), even if the
+number of devices is the same.
+2. There are more OpenCL devices than ADL. OpenCL stupidly sees one GPU as two
+devices if you have two monitors connected to the one GPU.
+3. There are more ADL devices than OpenCL. ADL devices include any ATI GPUs,
+including ones that can't mine, like some older R4xxx cards.
+
+To cope with this, the ADVANCED option for --gpu-map is provided with cgminer.
+DO NOT USE THIS UNLESS YOU KNOW WHAT YOU ARE DOING. The default will work the
+vast majority of the time unless you know you have a problem already.
+
+To get useful information, start cgminer with just the -n option. You will get
+output that looks like this:

+GPU FAQ:
+
+Q: Can I change the intensity settings individually for each GPU?
+A: Yes, pass a list separated by commas such as -I d,4,9,9
+
+Q: The CPU usage is high.
+A: The ATI drivers after 11.6 have a bug that makes them consume 100% of one
+CPU core unnecessarily so downgrade to 11.6. Binding cgminer to one CPU core on
+windows can minimise it to 100% (instead of more than one core). Driver version
+11.11 on linux and 11.12 on windows appear to have fixed this issue. Note that
+later drivers may have an apparent return of high CPU usage. Try
+'export GPU_USE_SYNC_OBJECTS=1' on Linux before starting cgminer. You can also
+set this variable in windows via a batch file or on the command line before
+starting cgminer with 'setx GPU_USE_SYNC_OBJECTS 1'
+
+Q: My GPU hangs and I have to reboot it to get it going again?
+A: The more aggressively the mining software uses your GPU, the less overclock
+you will be able to run. You are more likely to hit your limits with cgminer
+and you will find you may need to overclock your GPU less aggressively. The
+software cannot be responsible and make your GPU hang directly. If you simply
+cannot get it to ever stop hanging, try decreasing the intensity, and if even
+that fails, try changing to the poclbm kernel with -k poclbm, though you will
+sacrifice performance. cgminer is designed to try and safely restart GPUs as
+much as possible, but NOT if that restart might actually crash the rest of the
+GPUs mining, or even the machine. It tries to restart them with a separate
+thread and if that separate thread dies, it gives up trying to restart any more
+GPUs.
+
+Q: Can you change the autofan/autogpu to change speeds in a different manner?
+A: The defaults are sane and safe. I'm not interested in changing them
+further. The starting fan speed is set to 50% in auto-fan mode as a safety
+precaution.
+
+Q: I upgraded cgminer version and my hashrate suddenly dropped!
+A: No, you upgraded your SDK version unwittingly between upgrades of cgminer
+and that caused  your hashrate to drop. See the next question.
+
+Q: I upgraded my ATI driver/SDK/cgminer and my hashrate suddenly dropped!
+A: The hashrate performance in cgminer is tied to the version of the ATI SDK
+that is installed only for the very first time cgminer is run. This generates
+binaries that are used by the GPU every time after that. Any upgrades to the
+SDK after that time will have no effect on the binaries. However, if you
+install a fresh version of cgminer, and have since upgraded your SDK, new
+binaries will be built. It is known that the 2.6 ATI SDK has a huge hashrate
+penalty on generating new binaries. It is recommended to not use this SDK at
+this time unless you are using an ATI 7xxx card that needs it.
+
+Q: Which AMD SDK is the best for cgminer?
+A: At the moment, versions 2.4 and 2.5 work the best for R5xxx and R6xxx GPUS.
+SDK 2.6 or 2.7 works best for R7xxx. SDK 2.8 is known to have many problems.
+If you are need to use the 2.6+ SDK or R7xxx or later, the phatk kernel will
+perform poorly, while the diablo or my custom modified poclbm kernel are
+optimised for it.
+
+Q: Which AMD driver is the best?
+A: Unfortunately AMD has a history of having quite a few releases with issues
+when it comes to mining, either in terms of breaking mining, increasing CPU
+usage or very low hashrates. Only experimentation can tell you for sure, but
+some good releases were 11.6, 11.12, 12.4 and 12.8. Note that older cards may
+not work with the newer drivers.
+
+Q: I have multiple SDKs installed, can I choose which one it uses?
+A: Run cgminer with the -n option and it will list all the platforms currently
+installed. Then you can tell cgminer which platform to use with --gpu-platform.
+
+Q: cgminer reports no devices or only one device on startup on Linux although
+I have multiple devices and drivers+SDK installed properly?
+A: Try "export DISPLAY=:0" before running cgminer.
+
+Q: cgminer crashes immediately on startup.
+A: One of the common reasons for this is that you have mixed files on your
+machine for the driver or SDK. Windows has a nasty history of not cleanly
+uninstalling files so you may have to use third party tools like driversweeper
+to remove old versions. The other common reason for this is windows
+antivirus software is disabling one of the DLLs from working. If cgminer
+starts with the -T option but never starts without it, this is a sure fire
+sign you have this problem and will have to disable your antivirus or make
+exceptions.
+
+Q: Cgminer cannot see any of my GPUs even though I have configured them all
+to be enabled and installed OpenCL (+/- Xorg is running and the DISPLAY
+variable is exported on linux)?
+A: Check the output of 'cgminer -n', it will list what OpenCL devices your
+installed SDK recognises. If it lists none, you have a problem with your
+version or installation of the SDK.
+
+Q: Cgminer is mining on the wrong GPU, I want it on the AMD but it's mining
+on my on board GPU?
+A: Make sure the AMD OpenCL SDK is installed, check the output of 'cgminer -n'
+and use the appropriate parameter with --gpu-platform.
+
+Q: I'm getting much lower hashrates than I should be for my GPU?
+A: Look at your driver/SDK combination and disable power saving options for
+your GPU. Specifically look to disable ULPS. Make sure not to set intensity
+above 11 for BTC mining.
+
+Q: Can I mine with AMD while running Nvidia or Intel GPUs at the same time?
+A: If you can install both drivers successfully (easier on windows) then
+yes, using the --gpu-platform option.
+
+Q: Can I mine with Nvidia or Intel GPUs?
+A: Yes but their hashrate is very poor and likely you'll be using much more
+energy than you'll be earning in coins.
+
+Q: Can I mine on both Nvidia and AMD GPUs at the same time?
+A: No, you must run one instance of cgminer with the --gpu-platform option for
+each.
+
+Q: Can I mine on Linux without running Xorg?
+A: With Nvidia you can, but with AMD you cannot.
+
+Q: I can't get anywhere near enough hashrate for scrypt compared to other
+people?
+A: You may not have enough system RAM as this is also required.
+
+Q: My scrypt hashrate is high but the pool reports only a tiny proportion of
+my hashrate?
+A: You are generating garbage hashes due to your choice of settings. Your
+Work Utility (WU) value will confirm you are not generating garbage. You
+should be getting about .9WU per kHash. If not, then try decreasing your
+intensity, do not increase the number of gpu-threads, and consider adding
+system RAM to match your GPU ram. You may also be using a bad combination
+of driver and/or SDK.
+
+Q: Scrypt fails to initialise the kernel every time?
+A: Your parameters are too high. Don't add GPU threads, don't set intensity
+too high, decrease thread concurrency. See the SCRYPT-README for a lot more
+help.
+
+Q: Cgminer stops mining (or my GPUs go DEAD) and I can't close it?
+A: Once the driver has crashed, there is no way for cgminer to close cleanly.
+You will have to kill it, and depending on how corrupted your driver state
+has gotten, you may even need to reboot. Windows is known to reset drivers
+when they fail and cgminer will be stuck trying to use the old driver instance.
+GPUs going SICK or DEAD is a sign of overclocking too much, overheating,
+driver or hardware instability.
+
+Q: I can't get any monitoring of temperatures or fanspeed with cgminer when
+I start it remotely?
+A: With linux, make sure to export the DISPLAY variable. On windows, you
+cannot access these monitoring values via RDP. This should work with tightVNC
+or teamviewer though.
+
+Q: I change my GPU engine/memory/voltage and cgminer reports back no change?
+A: Cgminer asks the GPU using the ATI Display Library to change settings, but
+the driver and hardware are free to do what it wants with that query, including
+ignoring it. Some GPUs are locked with one or more of those properties as well.
+
+Q: I have multiple GPUs and although many devices show up, it appears to be
+working only on one GPU splitting it up.
+A: Your driver setup is failing to properly use the accessory GPUs. Your
+driver may be configured wrong or you have a driver version that needs a dummy
+plug on all the GPUs that aren't connected to a monitor.
+
+Q: Should I use crossfire/SLI?
+A: It does not benefit mining at all and depending on the GPU may actually
+worsen performance.
+
+Q: I have some random GPU performance related problem not addressed above.
+A: Seriously, it's the driver and/or SDK. Uninstall them and start again,
+noting there is no clean way to uninstall them so you have to use extra tools
+or do it manually.
+
+Q: Do I need to recompile after updating my driver/SDK?
+A: No. The software is unchanged regardless of which driver/SDK/ADL_SDK version
+you are running. However if you change SDKs you should delete any generated
+.bin files for them to be recreated with the new SDK.

 Basic *nix build instructions:
-	To build with GPU mining support:
-	Install AMD APP sdk, ideal version (see FAQ!) - no official place to
-	install it so just keep track of where it is if you're not installing
-	the include files and library files into the system directory.
-	(Do NOT install the ati amd sdk if you are on nvidia.)
-	To build with GPU monitoring & clocking support:
-	Extract the AMD ADL SDK, latest version - there is also no official
-	place for these files. Copy all the *.h files in the "include"
-	directory into cgminer's ADL_SDK directory.
-
-The easiest way to install the ATI AMD SPP sdk on linux is to actually put it
-into a system location. Then building will be simpler. Download the correct
-version for either 32 bit or 64 bit from here:
-	http://developer.amd.com/tools/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/
-
-The best version for Radeon 5xxx and 6xxx is v2.5, while 7xxx cards need
-v2.6 or later, 2.7 seems the best.
-
-For versions 2.4 or earlier you will need to manually install them:
-This will give you a file with a name like:
- AMD-APP-SDK-v2.4-lnx64.tgz (64-bit)
-or
- AMD-APP-SDK-v2.4-lnx32.tgz (32-bit)
-
-Then:
-
-sudo su
-cd /opt
-tar xf /path/to/AMD-APP-SDK-v2.4-lnx##.tgz
-cd /

-
-Where ## is 32 or 64, depending on the bitness of the SDK you downloaded.
-If you are on 32 bit, x86_64 in the 2nd last line should be x86
-
 	To actually build:
 
 	./autogen.sh	# only needed if building from git repo
-	CFLAGS="-O2 -Wall -march=native" ./configure

-MAY CAUSE TO YOUR HARDWARE. OVERCLOCKING CAN INVALIDATE WARRANTIES, DAMAGE
-HARDWARE AND EVEN CAUSE FIRES. THE AUTHOR ASSUMES NO RESPONSIBILITY FOR ANY
-DAMAGE YOU MAY CAUSE OR UNPLANNED CHILDREN THAT MAY OCCUR AS A RESULT.
-
-The GPU monitoring, clocking and fanspeed control incorporated into cgminer
-comes through use of the ATI Display Library. As such, it only supports ATI
-GPUs. Even if ADL support is successfully built into cgminer, unless the card
-and driver supports it, no GPU monitoring/settings will be available.
-
-Cgminer supports initial setting of GPU engine clock speed, memory clock
-speed, voltage, fanspeed, and the undocumented powertune feature of 69x0+ GPUs.
-The setting passed to cgminer is used by all GPUs unless separate values are
-specified. All settings can all be changed within the menu on the fly on a
-per-GPU basis.
-
-For example:
---gpu-engine 950 --gpu-memclock 825
-
-will try to set all GPU engine clocks to 950 and all memory clocks to 825,
-while:
---gpu-engine 950,945,930,960 --gpu-memclock 300
-
-will try to set the engine clock of card 0 to 950, 1 to 945, 2 to 930, 3 to
-960 and all memory clocks to 300.
-
-AUTO MODES:
-There are two "auto" modes in cgminer, --auto-fan and --auto-gpu. These can
-be used independently of each other and are complementary. Both auto modes
-are designed to safely change settings while trying to maintain a target
-temperature. By default this is set to 75 degrees C but can be changed with:
-
---temp-target
-e.g.
---temp-target 80
-Sets all cards' target temperature to 80 degrees.
-
---temp-target 75,85
-Sets card 0 target temperature to 75, and card 1 to 85 degrees.
-
-AUTO FAN:
-e.g.
---auto-fan (implies 85% upper limit)
---gpu-fan 25-85,65 --auto-fan
-
-Fan control in auto fan works off the theory that the minimum possible fan
-required to maintain an optimal temperature will use less power, make less
-noise, and prolong the life of the fan. In auto-fan mode, the fan speed is
-limited to 85% if the temperature is below "overheat" intentionally, as
-higher fanspeeds on GPUs do not produce signficantly more cooling, yet
-significanly shorten the lifespan of the fans. If temperature reaches the
-overheat value, fanspeed will still be increased to 100%. The overheat value
-is set to 85 degrees by default and can be changed with:
-
---temp-overheat
-e.g.
---temp-overheat 75,85
-Sets card 0 overheat threshold to 75 degrees and card 1 to 85.
-
-AUTO GPU:
-e.g.
---auto-gpu --gpu-engine 750-950
---auto-gpu --gpu-engine 750-950,945,700-930,960
-
-GPU control in auto gpu tries to maintain as high a clock speed as possible
-while not reaching overheat temperatures. As a lower clock speed limit,
-the auto-gpu mode checks the GPU card's "normal" clock speed and will not go
-below this unless you have manually set a lower speed in the range. Also,
-unless a higher clock speed was specified at startup, it will not raise the
-clockspeed. If the temperature climbs, fanspeed is adjusted and optimised
-before GPU engine clockspeed is adjusted. If fan speed control is not available
-or already optimal, then GPU clock speed is only decreased if it goes over
-the target temperature by the hysteresis amount, which is set to 3 by default
-and can be changed with:
---temp-hysteresis
-If the temperature drops below the target temperature, and engine clock speed
-is not at the highest level set at startup, cgminer will raise the clock speed.
-If at any time you manually set an even higher clock speed successfully in
-cgminer, it will record this value and use it as its new upper limit (and the
-same for low clock speeds and lower limits). If the temperature goes over the
-cutoff limit (95 degrees by default), cgminer will completely disable the GPU
-from mining and it will not be re-enabled unless manually done so. The cutoff
-temperature can be changed with:
-
---temp-cutoff
-e.g.
---temp-cutoff 95,105
-Sets card 0 cutoff temperature to 95 and card 1 to 105.
-
---gpu-memdiff -125
-This setting will modify the memory speed whenever the GPU clock speed is
-modified by --auto-gpu. In this example, it will set the memory speed to
-be 125 Mhz lower than the GPU speed. This is useful for some cards like the
-6970 which normally don't allow a bigger clock speed difference. The 6970 is
-known to only allow -125, while the 7970 only allows -150.
-
-
-CHANGING SETTINGS:
-When setting values, it is important to realise that even though the driver
-may report the value was changed successfully, and the new card power profile
-information contains the values you set it to, that the card itself may
-refuse to use those settings. As the performance profile changes dynamically,
-querying the "current" value on the card can be wrong as well. So when changing
-values in cgminer, after a pause of 1 second, it will report to you the current
-values where you should check that your change has taken. An example is that
-6970 reference cards will accept low memory values but refuse to actually run
-those lower memory values unless they're within 125 of the engine clock speed.
-In that scenario, they usually set their real speed back to their default.
-
-Cgminer reports the so-called "safe" range of whatever it is you are modifying
-when you ask to modify it on the fly. However, you can change settings to values
-outside this range. Despite this, the card can easily refuse to accept your
-changes, or worse, to accept your changes and then silently ignore them. So
-there is absolutely to know how far to/from where/to it can set things safely or
-otherwise, and there is nothing stopping you from at least trying to set them
-outside this range. Being very conscious of these possible failures is why
-cgminer will report back the current values for you to examine how exactly the
-card has responded. Even within the reported range of accepted values by the
-card, it is very easy to crash just about any card, so it cannot use those
-values to determine what range to set. You have to provide something meaningful
-manually for cgminer to work with through experimentation.
-
-STARTUP / SHUTDOWN:
-When cgminer starts up, it tries to read off the current profile information
-for clock and fan speeds and stores these values. When quitting cgminer, it
-will then try to restore the original values. Changing settings outside of
-cgminer while it's running may be reset to the startup cgminer values when
-cgminer shuts down because of this.

-GPU DEVICE ISSUES and use of --gpu-map
-
-GPUs mine with OpenCL software via the GPU device driver. This means you need
-to have both an OpenCL SDK installed, and the GPU device driver RUNNING (i.e.
-Xorg up and running configured for all devices that will mine on linux etc.)
-Meanwhile, the hardware monitoring that cgminer offers for AMD devices relies
-on the ATI Display Library (ADL) software to work. OpenCL DOES NOT TALK TO THE
-ADL. There is no 100% reliable way to know that OpenCL devices are identical
-to the ADL devices, as neither give off the same information. cgminer does its
-best to correlate these devices based on the order that OpenCL and ADL numbers
-them. It is possible that this will fail for the following reasons:
-
-1. The device order is listed differently by OpenCL and ADL (rare), even if the
-number of devices is the same.
-2. There are more OpenCL devices than ADL. OpenCL stupidly sees one GPU as two
-devices if you have two monitors connected to the one GPU.
-3. There are more ADL devices than OpenCL. ADL devices include any ATI GPUs,
-including ones that can't mine, like some older R4xxx cards.
-
-To cope with this, the ADVANCED option for --gpu-map is provided with cgminer.
-DO NOT USE THIS UNLESS YOU KNOW WHAT YOU ARE DOING. The default will work the
-vast majority of the time unless you know you have a problem already.

-To get useful information, start cgminer with just the -n option. You will get

-
-Q: I upgraded my ATI driver/SDK/cgminer and my hashrate suddenly dropped!

 submits no shares?
 A: Add the --scrypt parameter.
 
-Q: I can't get anywhere near enough hashrate for scrypt compared to other
-people?
-A: You may not have enough system RAM as this is also required.
-
-Q: My scrypt hashrate is high but the pool reports only a tiny proportion of
-my hashrate?
-A: You are generating garbage hashes due to your choice of settings. Your
-Work Utility (WU) value will confirm you are not generating garbage. You
-should be getting about .9WU per kHash. If not, then try decreasing your
-intensity, do not increase the number of gpu-threads, and consider adding
-system RAM to match your GPU ram. You may also be using a bad combination
-of driver and/or SDK.
-
-Q: Scrypt fails to initialise the kernel every time?
-A: Your parameters are too high. Don't add GPU threads, don't set intensity
-too high, decrease thread concurrency. See the SCRYPT-README for a lot more
-help.
-
-Q: Cgminer stops mining (or my GPUs go DEAD) and I can't close it?
-A: Once the driver has crashed, there is no way for cgminer to close cleanly.
-You will have to kill it, and depending on how corrupted your driver state
-has gotten, you may even need to reboot. Windows is known to reset drivers
-when they fail and cgminer will be stuck trying to use the old driver instance.
-
-Q: I can't get any monitoring of temperatures or fanspeed with cgminer when
-I start it remotely?
-A: With linux, make sure to export the DISPLAY variable. On windows, you
-cannot access these monitoring values via RDP. This should work with tightVNC
-or teamviewer though.
-
-Q: I change my GPU engine/memory/voltage and cgminer reports back no change?
-A: Cgminer asks the GPU using the ATI Display Library to change settings, but
-the driver and hardware are free to do what it wants with that query, including
-ignoring it. Some GPUs are locked with one or more of those properties as well.
-
-Q: I have multiple GPUs and although many devices show up, it appears to be
-working only on one GPU splitting it up.
-A: Your driver setup is failing to properly use the accessory GPUs. Your
-driver may be configured wrong or you have a driver version that needs a dummy
-plug on all the GPUs that aren't connected to a monitor.
-
-Q: Should I use crossfire/SLI?
-A: It does not benefit mining at all and depending on the GPU may actually
-worsen performance.
-
-Q: I have some random GPU performance related problem not addressed above.
-A: Seriously, it's the driver and/or SDK. Uninstall them and start again,
-noting there is no clean way to uninstall them so you have to use extra tools
-or do it manually.
-
-Q: Do I need to recompile after updating my driver/SDK?
-A: No. The software is unchanged regardless of which driver/SDK/ADL_SDK version
-you are running. However if you change SDKs you should delete any generated
-.bin files for them to be recreated with the new SDK.
-
 Q: I switch users on windows and my mining stops working?
 A: That's correct, it does. It's a permissions issue that there is no known
 fix for due to monitoring of GPU fanspeeds and temperatures. If you disable
