Surely there'll be some scope for OCing the RAM. Mine goes up to about 880mhz before it starts to loose performance.

The default on that CPU is 8x. But the max temp is 72 deg and the max vCore is 1.5v according to Intel.

Interesting, both these specs are far higher than mine. Intel says 62 deg and 1.33v for mine so there should be no worry about using 1.5v.

Too bad.

Alright, then set your FSB @ 425MHz (1700) and your RAM at 850MHz. Set the voltage on your RAM anywhere from 2.0-2.1 but no higher. Keep the same voltage on the CPU and see if it's stable by running Orthos small FFTs. If it's still not stable, first increase your NB voltage by one tenth; if still not stable, increase CPU voltage to 1.47 and try again.

Hmm, good find. I didn't take into account the 1333FSB. That would certainly explain why he can't set it to 9x.

Default Re: Help overclocking my E6750 alittle more!?

I'm not trying to crap on Xion here cos I know he's got far more experience than me, but I would say:

8x, 1.5 vCore, 800mhz FSB (or 1600mhz depending on how your BIOS displays it), 1:1 ratio RAM (try messing with the 'sync' setting if ya have it), 2.2v on ya RAM and set your timings to 'Auto' while you're messing with the CPU.

Work up from here 5mhz at a time. When you find the max OC, start messing with the timings a bit.

Just type 'intel support' in to Google and put your CPU no. in the box on the Intel page. They're all there, right back to the P4's.

EDIT: Just checked here >> http://images.crucial.com/pdf/datash...40-pinDIMM.pdf Your default memory voltage is 2.2 -+.1

I'm going to bed now dude so good luck and I hope it works out well for ya!

Not a problem, because I needed to be corrected on the multiplier. But you may want to edit that last post to say "400MHz" FSB just so he doesn't get confused.

Overclocking is something that comes easy from experience but is tough to communicate to someone else over the web. Most BIOS' usually vary in one way or another which doesn't make it any easier.

Well i lowered the memory to 2.00v ... set the cpu to 1.5v and have so far managed to get the memory to just over 900MHz .... and the cpu to just over 3.6GHz ideling at 40c - 41c .... that temp to hot? ..... gonna try lowering the voltage and do some Orthos stress testing.

Temps are about where they should be, and it looks like you're on the right path.

So what do you think a safe load temp i shoulk keep this cpu under is?

62C. Keep in mind that Orthos/Prime will push a CPUs temps much higher than other applications will. But for long-term benching try to keep it under 62C.

Ahh .. well im below that with Orthos so far, highest ive seen is 57c! .. its usually lower than that .. 54c - 55c! .... just trying to get the voltage stable now! .... so far at 1.42v and stable after 10 mins Orthos testing.... long way to go yet lol ... would like to see at least 8 hours stable.
