OC Noob needs your help!

ok so I got my new system up and running now to OC, only thing is its something I have never done before!

So I have a stock i5 2500k which sits at 30-35c idle and under full load for an hour using prime95 my highest temp was 56c. My cooler is an arctic freezer 13 pro and my case is the HAF 912+ with two 200mm fans and two 120mm fans.

Also have the Sapphire 6870 which idles 34-39c under furmark burn-in for half hour my highest temp was 71c

and my ram is 4GB Corsair Vengeance 1600MHz and mobo is ASUS P8P67.

Guidance would be much appreciated!!

Edit: Power pack is also 600w

Not too sure about the RAM or graphics card.

But with my 2500k I turned up the multiplier to 40 to start off with and upped the voltage until it didn't blue screen (I think it's a good idea to gradually overclock as you get to check temperatures). If the temperatures are under 62 then keep upping the multiplier followed by the voltage until you get a stable overclock with temperatures under 70c.

Each board requires different voltages as well as the individual chip itself so you won't find any exact numbers.

i have the same mobo and cpu, so anuyone who can help us with a bit more guidence would be much appreciated.

Any help? Do I have enough power? and are my temps bad for aftermarket cooler?

As long as the PSU is a good brand, you have plenty of power.

Overclocking on your CPU is done entirely by the multiplier. Leave the base clock alone.

Basically raise the multiplier then boot into Windows and run prime for a bit to see if it's stable. If it is, go back to bios and repeat. When you run into stability problems up the core voltage a notch and try again. There is a sticky at the top of the forum about safe voltages on Sandy Bridge.

Your temperatures seem fine to me. Anything under mid 70's core temperature is fine.
