OC' on a ASUS P5K

Thought I'd give overclocking a try.

I have a E6750 C2D
DDR2 PC2-5300 NON-ECC • DDR2-667 • 1.8V memory

I followed a guide but the BIOS options look much different to that.

I did try changing the multiplier but it wouldn't accept the new value.

Can anyone please explain "simply" what settings i need to tweak, i'd be most grateful

You need to go into jumper configuration i think thats what its called... and there u can alter FSB / Vcore and memory speeds.. once u change the options from auto you should see these

And you do know that you can only change the multiplier down, right?

Well the cpumultiplier is set to 8 in bios, but shows as x6.0 in CPU-Z.

I'm kinda confused :confused:

Anyway I upped the speed from 333 to 339 and it's now at 2.7mhz.
That all you need do?

You need to go into jumperfree config and change settings from auto to manual then you will see a lot more options you can adjust. Cpu-z is correct as you still have speedstep enabled. fire up prime or orthos and it will change to 8x. Your board is capable of 500 + fsb so is that chip probably with decent cooling. http://valid.x86-secret.com/show_oc.php?id=259140 heres one i prepared earlier

Thanks for helping, but i've given up! I upped it to 3.0hz and it wouldn't boot, got a "invalid or damaged system partition message". Put back to my previous clock which did work, but now same error, so had put it all at default.

Don't give up, try upping the cpu and memory voltages a notch or two but keep an eye on your temps.

Read a few guides about overclocking before diving in at the deep end. Check the beginners one on this site too

should provide most you need to know

You also need to keep a serious eye on the RAM speed, and change the divider as necessary. While you are trying to find the limits of the CPU, make sure the RAM runs below spec (but not too much) to eliminate it as a source of problems. It's all too easy to forget and boot up with the RAM at 1150MHz or something.
