Curently Prime stabe at 3.8 but really want to get to 4G if possible, whats the max Vcore i can put through the 9950 and still have a working system in a year and a halfs time. Temps are fine, hovering around mid 60s??

Try not to go over 1.4v as read in Windows.

^^ thats as high as i'm willing to go for as a 24/7 clock.

What are you needing for 4ghz?

ive tryed to get prime stable at 1.4 but it just wont happen, im benching at 3.9 now (using half hour occt CPU only, before priming) im a bit peed off at the p5Q making me down clock my mem anyway

(
im 3.8 prime stable at 1.34V, it just seems a massive leap to 1.4+ i suppose i should be happy with the 30% free boost hehe

What speed are you running the memory at?

Sayso · 11 Oct 2008 at 19:29

its locked so approx 900

might have to tighten the timings?

Wouldn't do any harm once you've finished the CPU overclock.

What a low vcore, my 9450 stable @ 3.77 with 1.525. My pc didn't boot at all @ 1.5 anyway.

1.525v in BIOS or in Windows?

Yeah 1.4v is quite low, but you can't push as many volts through the 45nm chips as you can through the older 65nm ones.

My Q9450 did 4ghz on 1.44v.
