Hi again guys,

I got my mobo back yesterday from Scan, and I proceeded to set it up outside the case to see whether or not it would recognize all of my RAM after the tech at Scan said that he didn't have any problems with the mobo at all..

So I installed my 6GB Dominators and fired it up only to see that it was still only picking up 2 sticks!!

I then removed the Dominator set, and installed my 3GB XMS3 set, again only 2 sticks were picked up, I powered down again, and I gently wiggled the module that was in the first white slot (nearest the CPU socket) and powered back up again, and voila, all 3 sticks were recognized...

So I shut it down, removed the 3GB set and put the Dominators back in, and they were all recognized to!

Anyway, I started testing with Prime95 Blend, and it ran overnight with the CPU @ stock, and the RAM at 1600MHz...

But if I try O/Cing to 3.2, it will fail Prime sometimes after a couple of hours, and other times it will fail after 10 minutes.. my PC either resets itself, or Prime just starts failing on threads...

I have also tried for 3.8GHz, and 4GHz, but I get the same thing...

I don't have time ATM to fill out all of my BIOS settings as I have to attend a Dr's appointment in a little while, but when I return from that I will fill out the BIOS settings so that you guys can see what I am running my system at...

It would be highly appreciated if someone could help me to find stable settings for my 4GHz O/C...

Here is my system specs:

CPU: D0 Stepping i920

HSF: Zalman CNPS9700NT w/ LGA1366 mounting bracket

RAM: 6GB Corsair Dominator 1600MHz C8, I also have a 3GB set of Corsair XMS3 1333MHz which I bought for testing purposes.

MOBO: EX58 UD5

GFX: Asus GTX280

HDD: 3 x SATAII

ODD: 1 x DVD ReWriter

PSU: Be Quiet! Dark Power Pro 850w

CASE: Silverstone TJ10-WMV nVidia Edition

I know I don't have the best HSF in the world, but it actually does not to bad of a job keeping my CPU cool, when I tried 4GHz O/C, the idle temps were around 40c, and it would go up to 83c when running Prime95 Blend, I have seen other people with higher temps than this using Titan Fenrir HSF which is supposed to be a decent cooler...

Anyway, when I get back from my Dr's I will fill in the BIOS settings so you guys can get a better idea of where i might be going wrong...

Thanks in advance..
