HELP Ocing x5650 on SR-2 w/48GB DDR3 mem

post #1 of 2
Thread Starter 
Hi guys, I need help/guidance/advice in over-clocking my machine. Here are the specs:

EVGS SR-2 mobo (A50 bios)
2 X x5650 CPUs (both liquid cooled)
4 X 12GB DDR3-1333 Mushkin Silverline Stiletto Triple channel memory (total 48GB mem)
2 X PNY Quadro 4000 2GB video cards
Silverstone Strider 1500W PSU
Couple of HDs, raid cards etc.

Essentially all the PCI slots, mem slots, HD slots are full! Yes, it's a beastly workstation.

I want to over-clock it to get more juice out of it (without frying it.) I want the CPUs oced to at least 3.6 GHz if not 4 GHz. Since this is my primary workstation I'd prefer stability vs setting a world record for speed.

I don't have too much knowledge or experience in ocing. Previously I've oced a few Asus mobos with single CPUs - failry simple stuff. But this is a dual processor setup and a very costly one at that, so I'm a little nervous in pushing it too far and experimenting with random values...not knowing what a lot of those values mean!

For the past couple of days I've scoured through the net, reading posts from various users, trying out many many values but everything fails. After every oc attempt the computer fails to POST and then I gotta reset the cmos and start again.

If anyone out there can help me achieve the desired results it would be greatly appreciated.

Thanks.

I've never overclocked on an SR-2, but those CPUs can probably do 3.6 on stock volts or hella close to it I would imagine. Certainly no more than 1.24-1.25v needed for vcore.

Only problem is all of that RAM is going to put some serious stress on your mem controller and limit your overclock.

Maybe you can fill us in on what numbers your tried so far ?
