As Topic...

I have guiminer -scrypt

I use the preset for 7850 high usage

One card (device 0) doesnt want to mine even though Ive had it mining before (only thing I changed was playing with OC settings, but have since reverted them)

The other card mines alright at about 290-180 khashs...

Ive scoured the internets and I and mot sure how to fix this..

Any advice?

Thanks

Have you tried using cgminer. I have two 7850's and use cgminer 3.6.2. Download cgminer and in the same folder make at bat file. Try these settings. If they are in the same motherboard and using Windows.

setx GPU_MAX_ALLOC_PERCENT 100
cgminer.exe --scrypt -o "pool url:port" -u "username" -p "password" -w 256,256 --thread-concurrency 8192,8192 -I 17,17

RJ,

Thanks for the response!!!

I may switch over to CG miner.
As an update I un/reinstalled all the drivers and kept the intensity below 19 and the driver no longer crashes, but Im at oraround 320-300 khash now.

Thank you so much for the settings, Ill try those later tnight!! :D

Does a motherboards PCI bandwidth matter? Will x16-x4 cripple my second GPU?
