Attention AMD Radeon 7950 users...

[pizza]

I have 7950s running stable at 670 mh/s (currently scrypt though). They are the new sapphire 7950s that newegg had a special on. i have 4 per rig running at this rate stable. I'll share the settings when i get home.

I have same cards please post settings

Has anyone solved the whole issue of card not being able to go above 8192 threads. I am using drivers 13.1 drivers.

I spent a few hours trying to get CGMiner working for LTC mining, but gave up because no matter what I tried it would reject my shares. I am now on the latest guiminer running with the 7950 high usage preset, intensity at 19, clocks at 1050/1525 @1.125V. I'm getting 625kh/s with around 0.8% rejected/stale shares. 

what version of the miner do you have? can you post link thanks. The newest one i downloaded didnt have any presets.

I'll post it later tonight.

setx GPU_MAX_ALLOC_PERCENT 100   type that into command prompt make sure its in caps! Or it will not work

I already solved it, it was a not enough ram on the system.

Thanks for the info. I'm expecting my order of 3x 7950s tomorrow and I'll try these settings.
