Help required diagnosing a problem....

[PoDd]

Hi All,

I'm really stuck with this one.

New Hardware being tested out of case:

P5Q - Pro
E8300
4GB (2x2gb)Corsair DHX 6400 4-4-4-12 and Geil Black Dragon Quad 6400 (4x1gb)
ATI 3870 512
Giabyte Odin 800W
AC Freezer 7 pro

The problem is Prime95 (blend) and memtest+ are failing on stock. Basic bios settings, all in line with appropriate stock voltages and timings. Prime fails after a few hours, metest at the end of test 3 - everytime, no matter what ram.

I have tried another set of ram (the geil), and exactly the same.

Prime was stable for 11 hours (i stopped it) when running small tft's.

I'm stuck on this one... Board? Ram(doubt all six sticks are bad - tried in pairs)? CPU?

All new so i have no history with any of it - except the 4 geil ram sticks.

Any help appreciated,

PoDd

yeh, by stock i don't mean Auto.

All set to how it should be: 4-4-4-12 @ 2.1 @ 800mhz.

I've since tried the ram in a friends pc and it passes memtest fine.

So, PSU? CPU, MB?

How to tell?

Cheers,

Tried northbridge upto .2 above default, in stages, no joy.

One thing i noticed, the motherboard is supposed to set the FSB term minimum volts to 1.1 if a 45nm cpu is detected. I have a wolfdale and the lowest available to me is 1.2?

Not detecting the 45nm?

At the mo there is only the initial relese bios available for this board (could be the issue), and yep, each stick fails individually...

Gonna RMA the board,

Thanx for the help folks...
