PhenomII x4 955 BE c3 OC help!

post #1 of 5
Thread Starter 
I'm running x4 955 c3 @ 3.8ghz,
cooler- amd stock copper heat pipe cooler,
voltage- 1.4(stock) + 0.50.
Ive only OC'd by increasing multiplier thus north bridge frequency,its voltage are at stock.
Dram timings are also at stock.
If I oc by increasing cpu's clock ratio the N.B frequency will increase,will that give me better performence then which I'm running now?
also what will be the safe N.B voltage increase?

To put it simple, no it won't bring any advantage. You might as well overclock the NB by using its own multiplier and usually you ca win a couple of MHz even without increasing the voltage. Careful though, increasing the voltage on the NB really increases power consumption.

This will help to get started -> http://www.overclockers.com/step-guide-overclock-amd-phenom/ . I've gotten great results from my 955 c3, but the stock cooler really holds it back. Anything over 3.6 and I would hit the thermal wall. I got a Mugen2 and some mx-4 and that took care of that wink.gif I can give you my settings currently, maybe that would help you play around with yours a bit.

fsb=215
cpu=3870 MHz x18 multi vcore=1.374
cpu/nb=2580 MHz x12 multi 1.23 volts
HTT=2150 MHz x10 multi 1.179 volts
NB 1.208 volts

Think I was getting 3.6Ghz w/ the stock cooler and 1.35 vcore. Of course, ymmv. If I can help more, let me know. Good luck and happy overclocking biggrin.gif

So you are stating that oc'ing by increasing multiplier is a better option!
