Hey guys! Long time no post. I'm still using the P5k I purchased 2 years ago and never had a problem with it. I'm using it till I can afford an I7 system. Anyway I'm trying to overclock my processor (specs in sig) I have it set to 3.6 at the moment and can't seem to get it any higher. But anyway system boots and all that but it crashes at random times. Any ideas? I'm still sort of new to overclocking.

Also the ram I'm using is this Newegg.com - G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Desktop Memory Model F2-8500CL5D-4GBPQ - Desktop Memory

Any help would be appreciated! Also any ideas on why I can't get the system to post beyond 3.68 ghz? It'll post at that but Windows refuses to boot.

Hi there, you mean the CPU and Ram volts? If so then yeah I tried adjusting those as well. The ram I have supports 2.0 and 2.1V according to the package. Also the timings on the package read as 5.6.6.18

3.68GHz is pretty high as it is for that CPU. The almost 100% overclock is already alot as it is. You may just be at it's limits.

Yeah, I was thinking about that too. I'd be happy with 3.68 even with 3.6 which is what I have it at now. Just wondering what's causing Windows to crash at 3.6 at random times and what is causing Windows to not boot at 3.68.

And heat as well. The 65nm can take heat, but its still not healthy

I thought about that too. I have plenty of fans and such but I'll keep my eye on the temps.

Isn't it obvious? It's unstable (and yes, an unstable overclock can sometimes even make Windows corrupt or act odd, even if it's fine 99.9% of the time, as I believe this to be what's making my Windows XP partition act up).

It could be anything simple from lack of voltage or too much heat, to something complicated but in simplified terms simply being something put under too much stress (either the CPU or any part needed for a certain computation).

My first guess would be the obvious that was asked first, and that was voltage. What do you have your CPU voltage set to in the BIOS, and what is it being reported as (use any software, but the more results, the better)? The symptoms of it not booting and crashing when set a bit lower point to this, but if that's not it, then it's simply beyond it's limits, in simple terms, for whatever reason(s), and at that point, it's not practical at all, if possible, to overcome it.

You're right, it was very unstable. The voltage I had it set to was 1.4750 then I upped it a little bit and had the same result. I have an Q8200 on the way it only has a 7x multiplier like my E6320. So I don't expect to get much out of it as far as overclocking goes. Also it was the only Intel Quad I could afford.

Wow I see you have your Core 2 clocked at 4.50 that's amazing!
