Problem Mining Litecoin with 5850

[DebitMe]

Any suggestions would be very helpful.  I notice here
https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison
that 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!

Did you lower your memory clock? I had BSODs with low memory clocks and no problems later when I reset the clocks to default or overclocked. Also, make sure your GPU doesn't reach 90C, that temperature isn't good for your GPU over the long run.

I can get 410 Kh/s, out my 5850

Use cgminer. I get 260kh/s on intensity 13.
