My System Specs

Default Shader Process OC

Just wanted to make a new thread regarding attempts to OC shaders to hopefully up ppd.
I don't know how charlie fared yesterday when he OC'd his GTX 9800x2 by bottoming out Core and memory and cranking up shaders. Temps obviously go way down and I've found I could up my shaders considerably over my previous attempts when core and mem were left at stock. Before I could only get my shaders up to 1458 from 1404 and didn't really see much difference with folding (minimal at best). Now by bottoming out my core and mem I can get my shaders to 1620 folding stable. Heres an example.

Before 666/1404/1150
Project : 5764
Core : GPUv2 Gromacs
Frames : 100
Credit : 384
-- GTX 260 Black --
Min. Time / Frame : 44s - 7540.36 ppd
Avg. Time / Frame : 44s - 7540.36 ppd
Cur. Time / Frame : 49s - 6770.94 ppd
R3F. Time / Frame : 48s - 6912.00 ppd
Eff. Time / Frame : 48s - 6912.00 ppd

After 500/1620/865
Project : 5764
Core : GPUv2 Gromacs
Frames : 100

-- GTX 260 Black --
Min. Time / Frame : 44s - 7540.36 ppd
Avg. Time / Frame : 44s - 7540.36 ppd
Cur. Time / Frame : 46s - 7212.52 ppd
R3F. Time / Frame : 47s - 7059.06 ppd
Eff. Time / Frame : 40s - 8294.40 ppd

Seems great...but maybe to great. I'm thinking thats just to much of a jump.
It's funny yesterday I complained about the 511 point WU's and today when I want one to compare they are no where to be seen heh.

I went a little overboard on the shaders a few times and got my 1st two Unstable machine errors so dern'it all to heck I guess I ruined 2
