Is there an target OC you're looking to get to? That'd make it easier.

I'm on a Gigabyte board myself, but in regards to OC'ing in steps, it's time consuming. Do it slowly and steadily and test everytime you get into windows. I personally use IBT for quick and dirty tests then Prime for the long haul once it passes IBT.

It took me ~ a full day to get my 4.0GHz.

Never know until you try. 66C is pretty good but of course you have aways to go on stability testing. Mine runs 4.0 like a dream but really starts heating up at 4.2.

Keep it under 80C while testing.

Well 1.3v would have been nice but it's not the end of the world. Under all that fatal error stuff would have been the 0X000000 code.

As someone just reminded me some of the Asus boards have an option for Full Phase power. If you have it, enable it.

At this point you might give enabling Load Line Calibration (LLC) some thought to even out the bumps. Normaly voltage drops when going from idle to load. LLC will prevent this and can even bump the voltage going to load depending on the board. Some people hate it as it isn't the way Intel designed the CPU's to work, Some people love it because it can work quite well with overclocking. Me, I just don't care, sometimes I use it sometimes I don't.

4.0+ is my goal.

Increased the voltage one more step passed 1.3.. and enabled LLC and FPP

Disable Speedstep, C1E, C-State tech, CPU & PCI spread spectrum if you have those options and have not disabled already.

As your stability testing here you might try glancing threw those guides I linked earlier. http://www.overclock.net/11209942-post12.html , http://www.techreaction.net/2010/09/...ide-lynnfield/

Everything is working well here at 70c on all cores 100% stress for the past 10-15 min. Where do we go from here? haha.

1) get CPU-Z and validate with your OCN screen name.
2) Join the 4GHz Club, post it here too.
3) More stability testing.

You can go whatever way you want on the testing. I'd suggest Intel Burn Test (IBT) for 20 passes of Max then 12+ hours of Prime 95 Blend.

I'm talking about trying for 4.2 or 4.4ghz. Should I increase the multiplyer or frequency?

First I'd get 4.0 stable and see where your voltage and temps are for that.

That aside just raise the baseclock. I'd just raise it a little at a time, get it to load, maybe some quick stability testing ( 3-5 passes IBT standard) then raise it some more. 191 --->193---->195---197---->---199---->201

201 X 21 for 4.2

211 X 21 for 4.4

At some point in there you will have to raise first the Uncore voltage and then possibly DRAM Voltage.
