My System Specs

Default Got any i7 OC tips?

I haven't received my x58 platform upgrade yet but while it's en route, I've been reading around for some overclocking know-how. I'm just wondering if anyone here has any tricks or advice that they can share or comment on any of the things below that I've read.

Some things I've found (not all are verified) are:

- If you turn off HT, you can get slightly higher speeds and better performance in many applications that aren't optimized for it.

-the p6t has trouble with 20X200- try 19X>200 or 21X<200 if you're shooting for 4000 with your 920

-On the p6t, try using the orange slots first- the black ones sometimes won't allow post.

-turn off everything but multicore, turbo, load line?? in your settings

-These things are hot- don't fret if your load temps are topping over 70

-be sure to stay under 1.65V for your memory

Mine has been crunching 24/7 between 65C and 70C no problem (on Air, mind you), no errors. My settings:

3820MHz (20x191): 1.3975V VCore and the secret sauce setting of QPI voltage at 1.38V. That's it. Only advice is keep vCore and vQPI as close as possible. Turbo is interesting, since it loads at 21x191: 4011Mhz, still on Air.

How will that affect the life span of your CPU?

Bound to shorten it but most of us will have moved on to another CPU well before that sustained heat takes its inevitable toll.

65-70 is perfectly fine for a CPU. When you get into the high 70s, that's when you start to have problems. Throttling occurs at those temps and degradation as well.

Those temps are the double of my current E6850. Currently Rosetta and temps are max 34 and 35. Not in the same league though as i7.
