You have a ways to go. This is my overclock on an 8800GS:aristide1 wrote:An NVidia 8800GS, low speed, shaders speeded up a bit, about 4189PPD so far.

I happened to have my Kill-A-Watt on my pc so I measured the difference between stock clocks and my current overclock. It looks like it takes an additional 12-14 watts for ~1500PPD. YMMV.aristide1 wrote:Dang, there's a decent amount of new folders that I wush would post their info.
I don't want to OC very much because my experience has been that the eneergy costs rise faster than the amounts of points gained. In fact that will probably be adquate reason to return this 8800GTS G92, but I will measure its actual consumption before the do that. And man can it create heat. Big time.
I'm running at 750/1850/1045 settings in rivatuner. It reports that the card is running at 756/1836/1044. It appears that overclocking is done indirectly by changing a relatively coarse multiplier. The shader clock appears to step by 54MHz, the core and the memory clocks by 5.4MHz steps.aristide1 wrote:Hey SKeptical Thinker,
What are you speed settings? I left everything except the shaders stock:
550/1800/800
The card becomes unstable at shader of 1900 but no BSOD. I cranked up the fan and the temp dropped below 60C, but that made no difference.
The benchmark machine has an ATI card in it. The differences in the architectures of the NVidia and ATI cards affect the relative performance on proteins of different sizes. NVidia has faster, but fewer, shaders so it can fold small proteins much faster than ATI. When the proteins are complex enough that NVidia cards have too few shaders to efficiently parallize the operations, ATI starts to have the advantage because it can do more operations in parallel.FartingBob wrote:After 24 hours of folding on my 4850 (8.9 drivers) ive only got around 2200 points. This is much lower than what others are getting with older, slower cards. Am i doing something wrong, or are nvidia cards just far more efficient than ATI cards at this?

Not too shabby for a $64 card.
Sometime the servers that accept completed WUs or the reports get backed up, and then everything gets counted all at once. I once completed like 53 WUs in a 3 hour period. Well, on paper I did.warriorpoet wrote:I had a very strange day about two weeks ago where I did 11k. Now I'm down around 5300PPD again. Wonder what happened...
8800GTX 630/1566/ 2006

There's a GTX280 and a 3GHz quad about to be added to the SPCR ranks, gentlemen
I'm jealous - I picked up an open-box special 9800GTX+ and even with it overclocked to 1890mhz shaders it still only does 4100ppd on the 511 pointers. The other bummer is that apparently there's a bug where if you mix cards with different shader amounts, one card runs dramatically slower than normal. Case in point, I had two 9800GT's doing 32-3500ppd on the 511's. I replace the slower of the two 9800GT's with the GTX+ and suddenly the GT that was doing 3500 drops to 2200. I check on folding forum and find out after the fact that it's a known problem.warriorpoet wrote:Heh. The GTX is cruising at 5580 PPD on a 511 point WU as we speak
That's no good. I have a 8800GTS 512 for dedicated folding coming Monday. Wonder if I should send it back...AZBrandon wrote:I'm jealous - I picked up an open-box special 9800GTX+ and even with it overclocked to 1890mhz shaders it still only does 4100ppd on the 511 pointers.
