hi good ppl :)
I have the "PT8 Neo-V MS-7043" mobo, and I just bought a Intel Pentium4 Prescott 3ghz (fsb 800mhz HT) for that motherboard (wich is supported)
I had a Pentium4 Northwood before @ 2.53ghz/533mhz fsb, wich worked FINE.. no problem at all
when I tryed the new one i started getting problems with my OS
internet explorer crashed sometimes
I got CRC errors in rar archives (wich unpacked fine with the old CPU)
I got errors in benchmark apps, like prime95 and 3DMark03
so I thought it might be the os, so I reinstalled the OS, didnt help!
I updated all chipsetdrivers, flashed bios, turned HT off in bios, tryed other PSU (running @350W 5V@35A | 12V@17A | 3.3V@20A, right now) to low?
I tryed the CPU in another computer, worked fine.. only did the torture test with prime95 and unpacked a rar archive, but it worked fine.
Ive got a tip that it could be the DDR RAM, I have PC2700 ram default, so I tryed PC3200 memories.. didnt help :((
feels like Ive tryed it all, with no success
one funny thing.. when I reset the bios (with the jumper) and boot up, the cpu workes fine for a while.. then after rebooting its back to normal "crappy" cpu.. dont know what to make of that :p
if any1 could help me just a bit Im more then greatful!
greetz!

I'm assuming your motherboard and bios is supposed to work with prescott and 800 MHz fsb.. correct ? If so, the one thing I can think off is a overheating northbridge.. try putting a fan on it ?

The northbridge is the chip underneath the 45° angled heatsink. Just touch the heatsink, see it its hot or not

Oh wait, it doesnt support your chip !

from your link:
Supports up to 3.06GHz and P4 Prescott / Prescott Celeron up to 2.8GHz.

I read that as Prescott and prescott based celeron are only supported up to 2.8 GHz. Your motherboard most likely can't handle the power requirements of the faster parts, I think you're out of luck.

I'd rather have the 2.53 northwood, unless I was wild about overclocking. Of course I'd never touch that board, unless it just happened to fall into a batch of junk parts I picked up from an auction.

If you had to up the voltage to get it to run correctly then I doubt you have solved the problem. Which prescott did you get? Post the specs of the CPU. Not the speed, but the model numbers.
