Folding Forum

Fellow folder and the well informed. When do you think we are going to be able to have a 100,000 points per day monster in a single desktop case?

As a point of reference, does any one out there have a top of the range I7/Xeon system and 3 to 4 GTX 280’s?

Its going to be a bit and probably not with this generation of cards.

My max out of my "Fastra" box was ~47k PpD.
But that was running the small/fast test protiens on v1.18.
Now with this mix of bigger/slower protiens and v1.19, I'm only doing ~39.5k PpD.

Luck............

You have to wonder how 4 of these things in a box would do: http://en.expreview.com/2008/12/09/gefo ... es-09.html

We will have to wait and see what the temps are like. Though 8 gpus and an I7. hehehe. only hope i'm in a job to beable to buy one next year.

How big is your desk?

A good GPU only design can get you 50 ppd/w. 100,000 ppd will draw 2000 watts with a nicely designed GPU only box if you can figure out how to stick the equivalent of 10-12 9800gx2's on your desktop.

A good CPU only design can get you 20 ppd/w. 100,000 ppd will draw 5000 watts if you can figure out how to stick 50 quad core processors on your desktop.

That's a lot of heat to get rid of..

We need a few generations of Moore's Law.

Current best seems to be 4x 9800GX2's for 40-50k PPD, depending upon the projects you receive.

I'll be investing in GPU folding technology when power usage comes down by a fair bit. I know that running my 2 PS3s at the moment at about ~125W each isn't really good PpDpW.. but its the total wattage i'm really worried about. I wouldn't like to have a 24/7 computer drawing any more than 300W.

The trick with GPU folding to Maximize your PpDpW is to use a low wattage CPU to drive multiple nVidia GPU clients.
That minimizes the hardware overhead.
For 300 watts used you should be able to get over 10,000 PpD.

If the new nVidia GTX295 (2x 240 Shaders) was a single-card (sadly it's not a singlePCB like the 4870X2, but a DualPCB), it would be possible! A GTX280 (240 shaders) can make about 8K PPD, so a GTX295 should be able to make 16K+ and if you install 6 in a ASUS P6T6 (Core i7 with 6x PCIe x16 slot), you should get 6x2x8K = 96K PPD, so with a bit overclocking you should be able to make a 100,000 PPD-beast!!

I would expect the GTX280 to get 6 - 7,000 PPD with the larger proteins.

Lets see. one Mountain mods duality case, a pair of P6T6 WS Revolution MBs with Intel i7, an even dozen of BFGEGTX2801024H2OWEs, two or three pumps & radiators, LOTS of power. (and money)

At 7,000 PPD/card, thats 84,000 PPD.

Definitely a monster, although it might be stretching the definition of a 'single desktop case.'

But the slots on the P6T6 are all single width.
So you'd be limited to 3 double width cards.
The K9A2 Plat will still take 4 double width cards.
To max a single box out you will need to find a WATX board which has the max number of x8 or x16 PCI-E slots in the right place.
Then you could fit 5 double width cards.

No. With watercooling the GTX 280s are single slot (as the BFG cards he mentioned).
