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:
Code:
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:
Code:

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

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.
