I'm at 4.5ghz with just under 1.3vcore with CPU temps never exceeding 62c and typically idling at room temp and averaging mid 50s under relatively heavy normal use load. Only time I hit 62 was on the max setting stress testing using IBT.
really? how much of a difference is there between the plus and the evo?
The price is like $10.00 less than CM Evo. The performance is almost the same. It really matters when the PC case has a lot of fans to drive air in and out of the case that makes the whole system cool.
I think most users can push up to 4.5Ghz without any real issues and stay within 'safe' limits. Of course 'safe' limits vary on the individual's tastes. Also, each chip is unique and there's no real way of telling how far you can OC. Mostly trial and error.
Mine (for example) can only push up to 4.3Ghz with an average vcore of 1.30v. Stable on 24 hours P95 Blend; 20 standard passes and 10 maximum passes on IBT. I cannot get anything past 4.3Ghz without BSOD and stress test fails. Constant tweaking of voltages and other settings didn't help either. I followed the guides here and elsewhere. I can only surmise that I hit the 'wall' with this processor.
I use a Scythe Mugen 2 and temps for each individual core never passed 65-66'c under stress testing in P95 and 73-74'c in IBT.
Good luck with the chip. Hope you have a better chip than mine.
I love my mobo. I do regret not buying the Pro version of it though, as I think it comes with a USB3.0 header adapter. With my case and mobo I had to run the USB line from the front panel and plug it in to the back. Or I guess I could just buy the header adapter. My favorite thing is the utilities ASUS provides for overclocking and monitoring temps and voltage.
Regarding the Evo, the only reason I bought the one that was a few dollars more was that the other didn't list the 1155 as compatible. Although I've read some Amazon reviews where folks are using it with the 1155, I just wanted to be sure so I spent the extra $4.
Both the 212+ and Evo have similar dimensions and performance.
The Evo reportedly shaves 1-2C off loads at top end.
1155 and 1156 use identical mounting hardware.= the same thing!
Either cooler will perform quite well for 4.5GHz clocks.
