4.0 is pretty much a given with a D0. Getting past 4.0 is mostly dependent on the chip and how much voltage it wants.

I have a h50 and love it for my 920. The genreal consensus is try to keep it under 80 during load. And you should always remove stock thermal paste and replace with MX2 or artic silver, do not use the intel paste it is crapo.

Also if you turn hyperthreading off you get a minimal decrease in performance and bring down temps by 5c or more if you decrease voltage. Hyperthreading can actually decrease gaming performance in some cases.

Thanks everyone im going to stay around the 65-70 mark.
As im on a x58 Sli LE mobo i have been looking and found this...
EVGA X58 Overclocking Guide
He gets 4.5Ghz in the end on air
So does this mean i could still get this being on water ?
Anything at 4Ghz or higher is going to take:
1. Knowledge with all of your Mobo BIOS Voltages
2. A superior Chip
3. A lot of patience running the settings through a gammet of stability testing.

I get a charge out of all these folks that purchase this new HW and just "assume" 4Ghz and higher "stable" will be easy cause someone else did it......
Yes Shansmis guide is good, but all Chips are different. All BIOS versions may require different settings etc etc....
I just recently update my BIOS to S227 (Classy 759 w NF200) and found I could bump my vCore dowm one notch and still pass 20x LinX Max Memory...couldn't on original BIOS....that was one setting vCore. You'll be primarily adjusting vCore, vTT and VDimm....(one at a time)...and testing!
CPU @ 3.83Ghz / RAM @1612 Mhz 8-8-8-24 1T -Bclk (QPI) 202 Mhz - no Turbo Boost - Mult x19 - Memory 2:8 - Uncore x16 (3627Mhz) - vDimm 1.64v - vCore 1.31875v (With VDroop) - Vtt +125mv (1.325v)

Idle: 38c/34c/38c/35c
LinX Load: 69c/66c/67c/66c (Saw 70c once with vCore bumped up one notch)

Good luck....

That eVGA dude's chip is like 1/10000000 to get that on air.

The general consensus is that DOs overclock way better than C0/C1s though.
A D0 is 99% able to hit 4.0GHz, the difference is the voltage required. Some people have hit it on voltages as low as 1.300v and some only make it at 1.4v

Folks have been spoiled by the ease of OC that was available on the C2D platform (I honestly believe intel purposely underbinned their lineup for this). It's not just the new folks with this attitude, I've been bit by it myself. ;)

It took me a good 6 months to push my old S939 3700+ over the 3G mark, but it certainly felt like an accomplishment when I finally got all of the settings dialed in to get there.

Absolutely Mr Wilson...100%...BUT 4 Ghz stable is still an accomplishment..whether CO or DO stepping!

Uh yes...thanks for bringing something to my attention I wasn't aware of........how many of these folks actually reached 4 - 4.5 Ghz STABLE, as apposed to a Vantage run??? You're correct, the DO does make 4 Ghz easier, but for low Voltage 24 / 7 use....you better know how to tweak properly, as apposed to slamming the vCore to it!

Huh!!?? No....can't see some "new to OC'ing" reaching 4.5 Ghz on Air and stable.....

I meant that eVGA dude's chip was like 1 in a million to get a chip that will even reach that clock speed at that low of voltage.
And where the hell did "new to OC'ing" come from? I never even referenced or implied that in relation to that eVGA staff member's chip. I just said that the chip was a very very odd specimen that is a one in a million.

In the overclocking community, 4.0-4.4GHz is not that hard to get stabilized for passes of LinX/etc. Most people planning to show off their overclocks don't intend to run their rigs at that speed for the rest of it's life. They just want to show off a couple hours of high volt, high temp.

Where the hell did the "but for low Voltage 24 / 7 use....you better know how to tweak properly, as apposed to slamming the vCore to it!" come from? I never mentioned at any point low voltage 24/7 use. Hell, I don't even see that in the OP.

Stable is LinX/IntelBurnTest running with a payload of a minimum of 4GB for at least 20 loops.
1.3v is very, very safe to run 24/7 as long as your VRM and processor are properly cooled.

It doesn't take a genius to test a processor's stability at different voltages. You reduce the voltage by one or multiple steps then just send it through LinX/IBT.
If all you care about is low voltage 24/7 use, you shouldn't be looking at overclocking an i7 LGA1366 at all.

Well said, couldnt have say it better.
