I hope to be able to squeeze ~7k ppd out of them..w/ less than 100 SP's, its going to be fun.

8800GS pulling 5.5k ppd?

Any results running multi-GPU platforms?

- Please keep in mind, that gpu is only running @ 700/1833/963 ...very far from my newly vmod'd GS.

As for multi client.. I am running ~3.8k PPD on the vmod'd GS, ~5.7k PPD on the GT + two single cpu, clients. [Right about ~10-11k for total sig'd rig PPD] I am gonna switch the vmod, for the 'non-vmod' to see what PPD I can pull with a single GPU.

You don't need to really overclock the cards much. The only thing that matters a whole heap is the shader clock speed...

Nitteo, what PSU are you using when you put 4 GT's on a MSI P6N Diamond?

I am not sure if the GTS is the same draw as the GT, but the smallest PSU I have on the rigs is the Antec Earthwatt 430 with 4x MSI 8800GT 512s and an E2180 CPU. The PSU is working fine in this setup, but I would not use it if I had a Quad as a CPU. I tried a Thermaltake 430 on 4x Asus 8800GT 512s and it kept shutting down. However this Thermaltake 500w works fine on the that same rig.

wow, and people think they have a need for a 750+ watt PSU when they are going SLI

I find that under Vista, you don't need much of a CPU when you're using GPU2 clients only. I have a pair of cards (an 8800GTS G80 and an 8800GT) running on a rig with a Celeron D 356. Even that Celly isn't put to the limit (average load around 66%). Thus, with a four card set up, you can easily make do with the cheapest dual core CPU you can find. If you have a Quad, you can easily assignall GPU clients to two cores (or probably even one) and fold happily away on the remaining three cores.

Now, under XP, that's a different story.. a single 8800GT uses about 50% of an X2 3600+ (if it would have been the celly, the poor thing would be panicking).

If you plan to GAME on that rig, then yes, you need more power. However, for folding, you don't need that much power (the GPU2 client isn't that power hungry a beast).

Thanks for reminding me.

THIS IS UNDER VISTA.

Vista seems to have a better way of distributing the load. I use e6300s and e2180s on my 4x GPU rigs. On Vista the most I see is 18%. I was tempted to buy Celerons to go cheaper, but e2180s were only $15 more!

For folding (4x GPUs) 500w is enough on a C2D, 600w for a Quad. 430w is pushing it, but doable (on the right PSU) longevity is my main concern for this 430w PSU. I wonder how long it will last folding at 100% load 24/7 7days a week...

I read somewhere the 8800GT has a 100w draw, so if you are on a budget, 430w is the lowest I would try.

woot! in the 200's now! Pretty quick for a single 8800GT and a Opty165 3Ghz. I'm saving my money for a new folding rig...so watch out as soon as I get!....which be a long time......so..blah

One of my 8800GT cards don't do as well on the 939 system @ mid 3K tops

What slot is it in Dukie?

Wow, that sounds weird.

~Gooda~
