Ello All.

Going to be attempting my first overclock in the next week. The components involved are listed below

Intel Core 2 Quad Pro Q6600 "Energy Efficient SLACR 95W Edition" 2.40GHz (1066FSB)
Asus P5K-E WiFi Intel P35 (Socket 775) PCI-Express DDR2 Motherboard
7800GT (soon to be a 700mhz 8800GT)
2 x Corsair 2GB DDR2 XMS2 DHX PC2-6400C4DHX TwinX (2x1GB) (4GB Total)
Zalman CNPS9700-LED CPU Cooler (As suggested in the Quad vs Dual overclocking guide by toms)
HiperX Type R 580 PSU (unsure of the quality of this device and it is making a annoying whiney sound when powered. If its dieing it will be replaced with a corsair HX 520w)
Antec 900 case
Vista Home Prem 64bit

What do you think of this setup?

I have read several of the guides dotted around and feel I am ready to attempt this. I am hoping for 3.0Ghz (1333FSB) or 3.2 (1422FSB?) From my understanding I should be looking at about an idle temp of 40ish and a temp under load of between 50 and 60 degrees. What sort of vcore are you guys having to use to keep this setup stable?

My question is this. How does overclocking the CPU impact on RAM. The ram I am running is 800mhz but I am unsure how this corresponds with the FSB speed and keeping a 1:1 ratio, which as I understand it is best to do? Will this effectivly de-clock my memory? or was it always underclocked due to the FSB of the mobo (266FSB stock x2 = 533?) Thats the bit i need explaining :)

Many thanks guys

Jon

Since you have PC6400 RAM, you can do 400(1600FSB) and CPU multiplier locked at 8 to achieve 3.2GHz so RAM divider is 1:1.

 

My Q6600 oced to 3.2 (400x8) with 1.425v set in BIOS, but CPU-Z show 1.340v.

I second slice's post: 400 FSB, 8 Multi, 3.2 Ghz and 1:1 memory divider.

For the Proc, I'd start at 1.35v, and since you're bumping the FSB a bunch (266~400 = 50% overclock) you'll want to bump that as well - Try a like amount. It should run stable. Beat up on it for a while with the Torture Testing program of your choice. If all is well, take a 10th of a volt at a time away until you get a failure. Then add that 10th back, and beat the snot out of it to make sure. Some guys will tell you 24 hours nonstop is the standard. But I usually try a few hours at a time while setting up. If it's good with me watching, then I'll leave a test running while I sleep. If it's good in the morning, then IMHO it's good.

On air, my box does this at 32c Idle and 57~60ish during P95/Everest torture tests. P95 beats up on your comp a little harder and is free. But to my mind Everest is worth paying for since it has a FAR FAR more complete toolset to help troubleshooting. YMMV, of course.

Thanks very much for the replies guys. massive help.

P95 is currently running at home with everything stock just so I can get used to the process of testing. Will check on it when I get back from work. I better not get any errors on a standard clock lol !!

I would start with that 1.35 and if you get no errors start reducing it.

Mine runs at 1.31 at 3.2 at idle. 1.264 under load.

It's not too hard, but my board didn't need any voltag bump on the NB to pull 400 Mhz.
