The two 1000W PSUs wouldn't be enough for the seven OC'd 470s and two Xeon 5680s with liquid cooling and all folding

Aqua Computer has single slot blocks for 480/470/465 cards as well as a 7 card bridge.

Regarding SR2 processors, the i7 series will not work.

Dual QPI chips are required, 55xx or 56xx xeons are currently supported.

You may be right about the total that that many 470's would add to the already BIG power demand. I don't think we would go into liquid cooling though. One leak on the carpet and the you know what would hit the fan! :surprised:

Well, that is a bit disappointing but it does not put it out of our reach.

You could use say, E5620's and get a reasonable overclock with them, however they key is with the multi-x. As already said, the system needs two QPI's and the Core i7 family dont have those. I sold my 8 Core Mac Pro to help fund part of this build, even so, its still way more expensive than I had planned. I have even heard some people selling their SR-2 because they could not afford to finish the build. I am confident that I should be able to get a good overclock on high end air cooling, if this turns out correct then I might just stick with that, rather than water cooling. I will update my farm thread soon, I do have many pics, but no time to upload at the moment.

We're just going to build another i7 rig with a 930 chip at 4 Ghz or more with a pair of GTX-470 superclocked cards overclocked even more. That'll replace the Q6600 rig currently in 24/7 use. That's my wife's all time favorite soft spot rig and there is no way she can part with it. I can't blame her either because that box has been to hell and back so many times its ridiculous. That rig alone sold me on Gigabyte boards forever. It is a tough as nails sweetheart of socket 775 rigs.

It should make you and Connie happy that the F4L server is a Gigabyte board with a Q6600

It does, indeed. Which model number board is it?

OMG, I didn't know we just passed 4 million points. :foldon

GA-P35-DS3L, I think.

My god that is the exact model Brad's previous socket 775 farm was built around. Every one of then with a Q6600 D0 chip between 3.0 and 3.5 Ghz. Outstanding board in every way. The P45 based models would overclock a little better some times but a board is virtually flawless when an engineer can't find a legitimate flaw in it, and Brad never did.

I'd love to see some pictures of that beast but there is no rush. I am very patient, except when it comes to our own stuff, then I go crazy!!

I started out running Gentoo on it and switched to Ubuntu 8.04. Has always run great while smp folding every step of the way

Even had it gpu folding for a while. Many 60 day (or more) uptimes in its time

Only reboot for important updates. Only OCd to 2.7 with Zalman 9700 cooler but always stable.

That is the way all of our Gigabyte boards are when running Unix. You can't make it croak unless you take something out of it with power ON, then you're really in trouble. Although windows is still largely alien to me and Brad despises it, Windows-XP with SP3 is surprisingly reliable. It's folded for a few months straight without needing a reboot for any reason. That isn't enough to make me want to buy it though!!

Brad here.

She's right. I tried my best to find a flaw in that board and never did. Spent a hell of a lot of time trying too. I wish they would have made an exact duplicate of it with a P45 norbridge and ICH10R southbridge at the time because there was no P45 model quite like it overall. But now there are equals to it in Gigabyte's P45 lineup so that matter is taken care of. The EP-45T-USB3P we bought to replace Butch's P45-UD3LR is easily its equal and then some, plus the benefit of having two (physically) 16 lane slots. Perfect for folding on a Q6600 quad. The true x8 interface of the second physical 16 slot doesn't hurt Fermi production one bit. For guys like Jester, who used 775 quads with the largest L2 caches, it was an outstanding board that would overclock like there's no tomorrow. Most Gigabyte boards do now. Lord knows of my love of the X58A-UD3R. Haven't seen a 920 or 930 chip yet that I didn't eventually make fold with unconditional stability at over 4 Ghz. Jester was our teacher so we couldn't have lost LOL.
