Title: Multi GPU + Intel HD graphics configuration
Post by: zodiac on January 29, 2014, 10:42:21 AM
Hello all, Been mining for a while on a single 290X. Since then I bought a second 290X and still everything was running smoothly. I don't know why I decided to install the driver for the Intel HD 4400 onboard graphics chip but since then I'm having trouble. I don't have a temp and fan speed reading, no fan control and my hash rate went down to 650KH/s per card. I'm trying to configure everything to work with cgminer but so far with no luck. here is my .bat file: setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://MyPool.com:correctPort -u My.worker -p MyPass -I 20,20 -g 1 -w 256,256 --thread-concurrency 22528,22528 --gpu-fan 20-75,20-55 --auto-fan --gpu-engine 947,947 --gpu-memclock 1400,1400 --gpu-vddc 1.100,1.100 When I run cgminer -n I get: [2014-01-29 12:38:50] CL Platform 0 vendor: Advanced Micro Devices, Inc.

Any thoughts? What am I missing to point cgminer in the right direction? Thank you for reading Z

The Intel driver may have disabled some features. Try uninstalling the AMD driver, reinstall the Intel driver, then install the AMD driver again. If that does not work: Get rid of the Intel Driver! AMDs driver architecture is already so bad, a 5 year old Korean kid could come up with a better one. You can't expect it to run side by side with another driver, or you gonna have a bad time.
