P4 2.4 OCing Temps and Weird problems

[TehSalt]

Hey all. This is my first time at the forums, and I'm glad to meet you all.

I just got into OCing on my system which is
Asus P4C800 Deluxe
Intel 2.4GHz with HTT

I've been OCing the external frequency by 5Hz each time, runnig a stability test (Prime 95 for 45 mins or so) and so far I've gotten to 225MHz (2.715GHz) with a max temp of 47C. I'm trying to get it to 250MHz (Which would be 3GHz) and I was wondering what sort of temperature would be bad.

Also, another problem I've gotten. I once used the Overclock helper tool in the Asus BIOS and got it up to a 20% Overclock, which would be 240MHz. So, I was trying to manually set the External Freq. to 230, and when Windows loaded and I started AsusProbe (For temp monitering) and Prime 95, I got a BSOD shortly into it (About 10 mins) and the system crashed completely. Windows refused to log me in until I reset the EF to 225. Any ideas why it would do this or what to do about it?

what memory are you using this sounds like a mem error due to too high a fsb. thats what happens try to relax the mem timings to like 2.5-3-3-11 or so and see if that helps

I'm using 2X512 Corsair XMS PC3200RAM

Interesting...I had my RAM set manually to 400MHz (Which it should be at) and it didn't work...I cange it to 'Auto detect', it detects it at 266MHz, but iit's stable now...

use 5:4 divider if you can, up vdimm to 2.7-2.8, relax ram timings 2.5-3-3-7 or 3-3-3-7), and up the vcore if you get instability

Well, all goes well. I sucessfully got it up to 3.0GHz. I set it to auto-detect the frequency of the RAm I have, and it now reads it as 266MHz instead of 400MHz...any ideas why it BSODs when I put it to 400MHz?

maybe your ram can't do 230 FSB - DDR460 at 1:1 ratio since it's PC-3200 rating at DDR400 unless you use a memory divider

It's weird, cause right now it's performing excellently, if not faster than before
