That's exactly what I intend on doing. Especially since I'll have access to LN2 (initially wanted to buy some dry ice but the vendor told me they were out, that all they had left was some LN2. Then, I lol'ed)

Awesome. What kind of HD4850 reaches 700/1200 on stock voltages? :O

I'd just like to point out some issues here and correct some misinformation that has been spreading in this thread.

If you guys actually bothered to read the original thread over at XS, which can be located here, you would have noticed a couple of things.

1.)
4.2GHz on air wasn't even close to stable. It was a suicide run. Getting a CPU-z validation is not hard. I was also able to do a suicide run of 4.2GHz on the stock cooler of my i7 920. The Ph2 result was was done on very good air.

2.)
The 4.7GHz result was not on air. It was achieved on dry ice.

3.)
There actually is a legitimate disadvantage to a 3-core CPU. Many applications are programmed to only use 2^n cores, and in the case of 3-cores, they will only use 2 of the cores.

These points aside, he has achieved a very respectable overclock.

Yes, but people do more multitasking than running multi-cpu-threaded applications.

Seems that the Asus I bought 2 days ago might do, 0.06v over stock at 750/1180 atm so far no artifacts, will try to push it a bit more after a fast 3DMark06 run

Yes, but 1 is still a power of 2. 2^0 = 1.
1) It wasn't stable yes, but I wouldn't say it wasn't "even close to" coz he was using the stock cooler and we both know that these are easily outperformed by aftermarket ones. So with a good aircooling it has to be possible to hit 4.2 while being stable.


2) Yeah, my bad, didn't saw that when I first read through the xbitlabs post, since then I edited my post. But then others already rectified that on the previous pages. And 4.7 on DI using an AM2+ mobo with DDR2 means you can technically hit 5GHz (and a nicer score on 3dmark for what matters) using one of these new AM3 mobos running the amd 790 chip.


3) Yep, that's perfectly right, Sony Vegas is an example of such a soft, that suxx but meh, if it's just for gaming or for the sake of ocing it, X3 phenoms have been proven to be better overclockers than the X4s. That and the X4 945 still has to be released on the market.

Uh oh, this debate might just start again.

What relevance do these facts of what you can do with your i7 bring this thread?
