!TIMMY!

Cheers for the replies guys. I changed the divider and went back to a 9 x multi. I have it OCCT stable at 3.6ghz (400 x 9) with 1.35 vcore with special add on auto (about 1.38v according to OCCT), 1.405v NB and 2.10v RAM @ 1066 5-5-5-15 2T. I will try Prime as well to make sure it is stable. Maybe 450 x 8 just aint possible with my setup.

Cheers for the reply. My PSU kept my other Q6600 @ 3.3ghz with 1.4v, ram @ 1175mhz with 2.15v stable. And now I am using less voltage on both the cpu and ram. I believe that SilverPower are a subsidiary of Tagan so I would have thought it would be up to the challenge.

I am trying to get my PC stable with my Q6600 @ 3.6 (450 x 8), and ram @ 1128mhz 5-5-5-15-2T. I bought this cpu 2nd hand because it can do 3.6ghz (450 x 8) @ 1.3375 vcore, 100.23% special add, vdroop: disabled; in a DFI X48 UT. I have had my ram at 1175mhz @ 5-5-5-15-2T before, but I have having problems getting them stable together. With the current settings below, it will last 1 minute on OCCT before the PC locks up. The max temperature any CPU core reached was 63C. My chipset temps are fine. The AS5 still need time to cure and my water cooling loop still needs to settle, so I think temps will reduce over time.

This does seem odd. My DFI NF4 SLI-DR won't work in DC with my Opty 146, but did with my 3700 and 3700 X2. I had the latest Bios as well.

I am after a AMD Opteron 175 that will do 2.8GHz (255FSB) so I can keep it @ 1:1 with my ram which will do 255FSB. I will have it under a Arctic Cooler Freezer Pro so voltages will have to be under 1.55v @ 2.8GHz (255FSB). Can anyone help me out? Thanks in advance. P.S. I live in the UK.

Ok, I need any 939 CPU, the cheaper the better. Reason is I need to test weather it is my Opteron 146 that is stopping me running dual channel p.s. I live in the UK.

What is the CPU?

Im from the UK and ive checked ebay but no luck. Can i get in contact with DFI in the UK?

Hello, I have the above motherboard, and i want the backplate as the person before me lost it. Does anyone know where i can get a spare one??? !TIMMY!
