An NVidia 8800GS, low speed, shaders speeded up a bit, about 4189PPD so far. :)

Added - Increased shaders again, about 3/4 of the way up the slider, now at 4822 PPD. 8)

2 * XFX 256MB 8800GT's @ 687/1718/752 (core/shader/mem) in one box. Both get around 4,850ppd but I have seen up to 5,200ppd on 'easier' WUs.

For info the 2nd 8800GT is running in an open-ended PCI-E 2.0 4x slot but achieves almost identical ppd to it's twin running in the regular PCI-E 2.0 16x slot.

Added - An 8800GTS OC'd - About 5200PPD. It's about to get interesting.

You have a ways to go. This is my overclock on an 8800GS:

http://www.techpowerup.com/gpuz/34vev/

Here are my benchmarks from FahMon:

Code:

 Credit  : 480


 -- FAH-NV --

 Min. Time / Frame : 1mn 20s  - 5184.00 ppd
 Avg. Time / Frame : 1mn 20s  - 5184.00 ppd

 Project : 5504
 Core    : GPUv2 Gromacs
 Frames  : 100

 -- FAH-NV --

Not too shabby for a $64 card.

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 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.

My 8800 GTS draws 85 watts and makes an excellent space heater. Noisey too.

Added 8800GTS becomes an RMA, a 2ns 8800GS uses half the power, delivers 80%+ of the points. It's a no brainer.

My Radeon 2600xt, 1100 points. still more then the core it wastes...

I have an 8600 "attempting" to fold but it crashes so often I only get 250-350PPD.

not sure if it was a bad batch of WU or what but the past few days it actually completed several WU in a row - then the weather turns hot and I shut my PC off last nite.

but the regular SMP client is still chugging along.

You need one of the utilities that displays GPU temps, and Rivatuner so speed your GPU fan which is running too slow.

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.

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.

When I increment any of the clocks to the next step, the card continues to run, but the folding core declares that the machine was unstable. EVGA's precision tool is even more conservative. According to it, all of the clocks I am running cause the card to be unstable.

In any case, on my card the most important clock is the shader, followed by the core, then the memory. It's hard to quantify due to the bizarre interactions between the core and shader clocks. It appears that you have to move them both up together to maximize performance. At some specific values for the shader clock, the core clock falls to 100MHz.

Fire up the hardware monitor in rivatuner to see what is happening. That helped me out considerably.

Of course, YMMV.

Well with the current batch of WU's my GPUs are worth barely more than 3000 PPD, a long ways down from the 4500+ PPD there were earning just a week ago.

And if that wasn't enough they also are causing large lags in 2D performance, which FAH team is well aware of, for all that's worth.

:?

I was going to get a mobo with 4 PCI-E X16 slots, and 4 video cards, now I am far less excited about the whole thing. :?

I'm having a problem with my reserator, I can't fold until I solved this and I don't know what to look for.

Current temps:
49/40 °C idle (core/ambient) (heavily underclocked: 268 core / 675 shader / 450 memory - rivatuner).
As said, the aluminium reservoir in the back does all the cooling.

Open it up, ditch the default pump and somehow (this is the thing) connect the outside tube connector to the radiator, otherwise the water will never go through it :?

Shouldn't the fluid that exits the GPU attached block be warmer than the fluid entering the block?

Can you feel a difference with your hand?

My HD4850 at stock speeds has gone from about 1600 to about 3000 points per day since I installed it in July. Yay software engineers - Let's hope it keeps climbing.

Im new to GPU folding, installed it on my 4850 yesterday and OC'd to 700mhz/1050mhz from 625/990, so should get some nice points out of it, although i dont keep my PC on when im not using it so i doubt i'll be topping any leaderboards..

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?

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.

The view from Stanford is that once the software for both cards is fully optimized and the proteins are complex enough to saturate both architectures, the performance differences will be relatively small.

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
e6600 @ 3GHz

There's a GTX280 and a 3GHz quad about to be added to the SPCR ranks, gentlemen :twisted:

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.

Eh. I'm a poop. I looked in the wrong place.

My current overall average (1wk) PPD is ~6100, GPU ~5900.

I've got a GTX260. GPU 650 MHz, Mem 1150 MHz, Shader 1400 MHz. Factory overclocked from ASUS.
I'm running that card and a PS3 and averaging about 7000 PPD combined.
I should also mention, my card is the 192 processors, not the 216

Welcome Einstein. Oh you'll be bright red in no time (a week) over here:

http://folding.extremeoverclocking.com/ ... s=&t=31574

Then you will race up the ranks and end up on page one, just like WP. He's on page 2 already.

Are you einsteingodel? I don't see any other einsteins on our team at the moment. :shock:

gtx280 is installed, but I have to run the stock intel + Zotac coolers for the next two weeks. My ears are bleeding! :roll:

In other news, I'm adding an 8800GTS 512 to it Monday. Should be good for some points :twisted:

Einstein-- WELCOME :)

Heh. The GTX is cruising at 5580 PPD on a 511 point WU as we speak :D

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. :(

That's no good. I have a 8800GTS 512 for dedicated folding coming Monday. Wonder if I should send it back...

BTW, FAHMon just reported average speeds of 6100PPD on a 511 GPU WU. This is with 3x GMP cores on the CPU :)

240 processing cores FTW!
