After a quick bit of research I could make Biffa's SR-2 look like little boys folding if I could get my hands on some 6xxx series Opterons.

I think somewhere in the region of 220k PPD is possible, knocking out nearly 2 Bigadv in a day

I was under the impression that the AMD Opteron 6174 was pretty close to the Intel Xeon X5650 when it comes to bigadv WUs.

There are boards available that have 4 CPU sockets.

Four of the Opteron 3136 = 48 Cores @ 2.4ghz

http://foldingforum.org/viewtopic.php?f=55&t=14757&sid=91bb40dbf7a9ca0882dae7da6acbd2ce#p145568

The above link has a table of the fastest bigadv rigs on the Folding Forum.

A 24 Core opteron @ 2.8Ghz takes 15.75hrs to complete a P2681 or 15m27s TPF, while running 23 cores.

From my experience going from a Athlon dual to Athlon Quad a the same clock speed frame times scale in a linear fashion.

This would leave the 48 Core theoretically somewhere in the region of 6 mins tpf.

Scratch just noticed someone is folding on a 48 core Opteron and Folding doesnt seem to scale across that many cores well.

He's doing something wrong I reckon, I posted in that thread.

Anyhoo.. would be awesome to see a quad 3136 rig :) I used to build big oracle servers with quad opterons so I would love it!

Have you seen the guy with the SR-2 and 8 :eek: GTX480's?

Yes I have an A/C unit dedicated in the room for this. The 6 water cooled GTX 480's are cooled by two sets of GTX360's(radiators) each with 3 120mm fans.
Power supplies are 2X 1200w, 1X 800w with dedicated circuit, and yes this is my own personal unit.

Yep.. I'm smallfry :)

Just for reference, with the right WU (say P2692) a SR-2 with X5600 Xeons at 4.2Ghz can hit 00:11:17 TPF for around 162,400 PPD :eek:

Do want! :eek:

My 460 is now at 850/1700 which has got me 11.3K PPD on a 6800. Was around 10.4K at 800/1600. Might push it up to 900/1800. What voltage is recommended at those clocks? Still on whatever MSI has set atm.

Need to OC my server! It's just being arsed to go up into the attic to do it lol. Gotta write down what settings I used on my main PC as the boards are somewhat similar. Too lazy to relearn how to OC the i7 lol.

Cool, will give that a go later. Lost about 2 hours of GPU foldy time last night. Restarted the client with the -oneunit flag intending to up the OC. Forgot about it! :p
