Any suggestions would be very helpful. I notice here
https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparisonthat a 5850 should be getting more than the 260-270 that I am currently getting out of it. But when I turn my gpu_thread_concurrency up to 6500 like it says (currently at 6144) my machine crashes and I get the blue screen of death. Any ideas on why this would be happening or tips on how to increase that speed?
Also note that I am using Reaper to mine with.
Thanks for any help in advance!!
Can't help you with Reaper as I use cgminer. (2) 5850 - 825 core, 850 mem, int=17. These are averaging 694 Kh/s @1.058 vddc. Those comparison charts are not set in stone for every card and as always, YMMV. Lot of factors come into play, quality of PSU, overclock-ability of GPU, stability of drivers, etc.
Good luck!
