Need help overclocking Phenom II x4 945 C2

post #1 of 11
Thread Starter 
I wanna get it to 3.6 Ghz. By having a 240 FSB and x15 multiplier
Don't know how much voltage to put though.
I know basic overclocking and stuff.
My cooler is a Hyper 212+ so everything is fine.

Also, how much of a voltage boost do I need for a 2400 NB speed?

my buddy and i have the same C2 chip that u have....these are the voltages we used to get to 3.8ghz

CPU - 1.45v
CPU-NB - 1.3v if i am remembering correctly

He has the chip right now i don't let me know how it goes and i can always find out from him what settings he uses, or i can just put u through to him.

And these volts will be fine with some sinks on the mosfets right?
ramfan told me it's fine up to 1.5v
Do you think I need that much voltage to get to 3.6?

Naw i doubt u need more than 1.5v, if he gets to 3.8ghz with 1.45v 1.5v would be for like a 4ghz OC, and yea sinks on the mosfets would be fine, i have a so called board that is prone to blowing up and i had my voltage at 1.6v for a day once and guess what, its still here kicking away...so just keep it within the 1.5v zone and u'll be ok..

Remember the C2 chips are 125watt so more power and more heat, if you do go up that high in voltage make sure to keep an eye on ur temps.

Let me know how it goes and PM me if you want more help...i will ask my friend to join in.

yeah. 1.45 or a bumb or 2 higher unless its a weak chip. you shouldnt need any extra voltage up to 2600 on the nb. havent heard of a ph2 needing more to only get that high.

shouldnt need extra on the nb*
depends on the mobo in both cases.

In the case of the C2 chips 62c is the critical temp...but for safety when overclocking people around here would say 55c is the limit, although my friend did have his C2 945 @ 75c while folding....it thought it was some other temp and just ignored it lolz...but never the less, the chip still works...you may not be that lucky...keep it below 60c and u'll be fine.

yeah try to not go over 55. performance starts taking a hit above that. if you got a good seating on your cooler you shouldnt have to worry about, just keep an eye on it

the 212+ is a really good air cooler. if your volts are low and the heat is too high, a) get a pair of good flow fans or b) try a reseat on the 212, wait. what case do you have ? does it have good airflow characteristics ? intake, exhaust, side fans, wire management ?
