Phenom ii 555 needs 1.525v to keep 4GHZ?!

post #1 of 9
Thread Starter 
Hi, I'm currently overclocking my Phenom ii x2 BE to 4ghz and was wondering
if 1.525v is way too much for my chip and could burn it to a crisp?
Temps at load are ~ 34c and My HSF is Coolermaster Hyper 212 Evo.
I'm really new to overclocking, so I basically just put the volts to 1.5 and kept bumping the multiplier up.
Someone please tell me if I'm doing anything wrong here

Also, dont suggest unlocking to quad ,
as I have tried so many times and my mobo just wont do it, Unless theres some magic (GA-990FXA-UD3)

Cheers, OCers.

1.55v is safe max voltage. You can push farther but it will degrade your chip.
Also you should bump multiplier, then voltage when it doesn't boot. Not voltage then multi. That's bad.
Also 34c load is pretty low for that voltage, you're talking P95 load right?

as long as your load temp is accurate your fine....maybe a future bios upgrade to help with core unlock
for a performance boost next step is to overclock your cpu/nb....something in the 2600 to 2800mhz area should be doable at around 1.3v

Oh okay, I dont really care about this chip, its more my motherboard I care about and this cpu only cost me $50
Yeah at 100% load on P95, ~35c
I put the voltage to 1.4 and then boosted multi until it stopped running prime, then from there i did it in small increments..

1.55volts and 62c on the cores is fine for 555BE.

You an get to 4GHz either using multi, FSB or combo of both. I've tried all 3 methods. Neither is wrong or bad. Altering the FSB adds some difficulty for a little more performance.

Personally I have just settled for rasing the Multi on the CPU (x20) and raised the the multi on the CPU/NB to give 2600MHz. (might have to raise the CPU/NB volts to 1.25-1.3)

Keep HT Link speed at 2000.

What mobo are you using. Depending on its power phases and cooling features it may not be wise to do too much overclcoking.

1.55v is way high imho for a 555be with hyper 212 evo. i used to have one clocked at 3.8 ghz, unlocked the 2 other cores and had it running fine at 1.4v.

its funny, i sold that chip to someone a few weeks back for that price, it could be you lmao

Haha, Nah i bought mine off a mate because he thought it was dead, turned out to be his mobo.
anyways, general opinion = 1.55 is too high?
I dropped it to 1.475 and now I have 3.9 ghz. frown.gif Now i dont get to say 4ghz.. tongue.gif

Not all CPus are the same. Mine unlocks to 3 core as one core is a dud and needs a lot of volts to make that third core stable. As a two core it uses a lot less volts for 4GHz.

What I was saying is that its ok to use 1.55v max without killing your CPU as long as you can keep under 62c. Always great if your cpu uses a lot less.
