What is stopping me from OCing more?

post #1 of 16
Thread Starter 
Hi there,

My sig rig is what im using here, and when i hit 2.62Ghz I can't seem to OC more. I'm not sure why, I haven't attemped to OC before but im sure the 2.62 is stable but when i go past 2.62 I just freeze when booting windows. I have the vcore at 1.550. My 2.62 Idles at 39 and 48-51 under load. I want to get some extra juice out of the processor .

Thanks guys!

Well memory speed could be holding you back. Try changing the mem to fsb ration is you're ram is clocked too high. Have you tried to go a lot farther past 2.62? You might have hit an fsb hole. Have you pushed your fsb voltage up at all? that usually helps when done in small increments.

For some motherboards that I've played with, yes.

Darkspearxz, is your 3800+ a Manchester core? Manchester's become voltage hungry around 2.6-2.7Ghz. Are you able to post CPU-Z screenshots of your OC at 2.63Ghz?

Let us know

Good luck

Yes it is a Manchester core. After changing my RAM back to stock 200MHz I managed to get 2.642GHz. I attached a CPU-Z screen. Thanks

Darkspearxz, that's very nice and close to a Manchester's limit. Have you tried to push it more? How much vcore are you running? How is that A8N-SLI treating you?

Good luck

I have tried using 2.65 but hangs at startup. My Vcore is at 1.550. The motherboard is nice, but since the stock chipset cooler stopped working i had to change to his massive heatsink and now I can't fit dual slot graphic cards.... Thanks!
