I want to still overclock and I want to be able to put multiple GPU's in for folding. Can anyone help me on find a new board or even a good used or refurbished board.
Thanks.

Unfortunately, the 775 socket has been more or less discontinued, so its hard to find new boards, especially ones that overclock well, so I would simply advise you to keep an eye out for boards that members here on OCN are selling off. P45 based boards are known to do well, and I think 780i's aren't too shabby either. Is multiple PCI express slots a requirement? Then you might want to look into an X48 board also.

Have you tried playing with overclocking at all, or will this be your first attempt? First of all, it would be helpful if you filled in your "sig rig." Just click on "Rigbuilder" in the top right corner of any OCN page and fill out what you know.

And here's a good how-to guide for Core 2 Duos and Quads to help get you started: http://www.overclock.net/t/198072/howto-overclock-c2q-quads-and-c2d-duals-a-guide-v1-1.

Well, I'm officially no longer an owner of any LGA 775 platforms or PCs. My Core 2 Duo E8600, Xigmatek HTD-S1283, Maximus Formula, and 8GB of Corsair DDR2 800MHz RAM have been sold and, as of yesterday, shipped. They're gone, and I already miss them. I hope this club goes for a while yet, because it's got life in it. I'd still be with it and feel it's still worth it if I didn't get something I couldn't turn down over it. I wanted to keep it and try and get a Core 2 Duo E8700 for it one day, but A) I don't have the will to put that much money towards a secondary PC I hardly use, and B) I wouldn't use it much, so it's more practical to pass it on. There's solace in knowing someone else is likely going to do it more justice than I'd have by keeping it.

This is the first pc i OC. I had it at 4.12 ghz stable, but i soon found out it was not a very good idea considering i have a stock cpu coole, so I tuned it down to 3.5 tongue.gif. The thing i was wondering most about was, even if i set down the multiplier, I cant raise the FSB over 400. It wont boot.

@lefze

What motherboard and RAM do you have? It seems like a lot of Core2Duo/Quad overclocks are limited by FSB speed.

And keep an eye on your temperatures, no matter what cooler you have. You'll want to keep it under 70C during heavy loads/stress testing. Prime95 is a common overclock stability tester that puts a heavy stress on CPU, FSB and RAM. And its also a good rule of thumb to try to keep vcore at or below 1.4V, in case you were getting up that high.

Lastly, you can edit your posts by clicking the little pencil icon in the lower left of the post's "box." thumb.gif

I have an asus P5Q pro. I dunno what ram I have, but its old. People seems to have different opinions on the max acceptable heat level, but ill try to push it down 5C. (It reached max 76C at both 4.07 and 3.8. now i have tuned it down to 3.75) also I cant change the vcore without getting an error/bsod/not able to boot :S

Yeah, the maximum acceptable heat really depends on your personal preference and how much you want to push your processor. I've heard up to 75C is fine under heavy stressing, but I like to try to keep things on the cooler side. Getting an aftermarket CPU cooler would be beneficial, my H70 keeps temperatures below 60 at all times. cool.gif

And try upping the FSB voltage, and NB voltage up a little as you increase the FSB, this should help with stability. You can check out this post from the P5Q club for some helpful info.

For me, I think I have vFSB and vNB at 1.2V with FSB at 450, but my RAM treats me pretty nicely, so you might need to go higher. You can also try to "loosen" the RAM timings by increasing them by one or two as you increase speed.

You can submit and post a validation with CPU-Z that will give the RAM manufacturer and speed, which will be helpful.

That's idle surely, right? Right!? If that's under load, that's amazing. I can see the lower cache resulting in less heat but that's still incredibly low. My Core 2 Duo E8600 @4GHz was between 29C and 34C idle and under 60C almost all of the time and I considered that very good.

Intel E6600 (Wolfdale) @ 3.68Ghz

My board is my limiting factor with this chip, I picked up an Asus P5 G41T-M LX3 since it was the most expensive and most modern feature packed board I could get new from MSY.

33 degrees under load.

Picture is of the current ghetto rig waiting on funds for a HTPC case.
