i7 2600k ~4.5 GHz
8gb ram 1333MHz

50 runs of linx for over 2 hours, max temp ever reached on the hottest core was 81C, it stayed around 79C for the most part. The other cores were below 78 most of the time.

It also did 8 hours of prime95 in standard blend mode. temps never exceeded 76C in prime95.

In games, my temps never exceed 62 for the most part. In rendering I never get above 70C

Is my overclock stable? any suggestions?

no reply???

Very few are doing overclocking with this beta OS. There is a very strong possibility of damaging their hardware as this is an early beta release.

If you want an assurance that your overclock is OK you shouldn't be overclocking in the first palce - it is up to you and no-one else to satisfy yourself that all is OK since what you can get from any particular hardware is unpredictable.

Overclocking hardware is NOT a bright thing to do with a beta OS, which is what Windows 8 CP is, & so will the RP coming in June be.

Being that Windows 8 has low hardware requirements, it's very possible that an overclock will be of little benefit to the user who already has a top notch CPU & GPU at the time of Windows 8 becoming Retail.

Overclocking a CPU, pushes it beyond it's advertised SAFE capabilities.
That will definitely shorten the life of the CPU.

If you want a faster CPU, then BUY a faster CPU.

I spent 30 years, building PC's and never once have I ever set one up for overclocking.
Let the Bios set the proper clock speed and voltage levels for your CPU and ram and you'll have a nice stable system.

I was checking the specs on that CPU, & for Windows 8, 3.4GHz (max 3.8GHz) ought to be plenty. Windows 8 won't be a resource hungry OS like Vista is.

That CPU also isn't cheap, at $326 last year. Many cannot afford that much CPU. But if you're insisting on more speed from the CPU, like TM stated, buy a new one & sell the one you have. There are i7's that runs at over 4.0GHz, w/o overclocking.

This produces more heat, excessive wear & tear on parts, not just the CPU, but the MB & RAM also. Because many who does this isn't satisfied with speeding up just one component, next will come the RAM & GPU. If there isn't adequate cooling, components are going to sizzle.

I've been told that I could squeeze 2.4GHz (or to play it safe, 2.0GHz) out of my AMD Athlon X2 3250e, which runs at 1.5GHz, but it was built to run at that speed, it's what it is. A low end CPU. I'd rather get another Windows release out of it (Windows 8), then sell it on eBay with the rest of the overpriced junk.

To answer your question, a CPU that was intended to run at 3.4GHz (3.8GHz max), 4.5GHz is pushing it too far. Sell the one you have & buy one with the speed you want. That's the best advise that I can offer.

Seems like you are running fine.

i already try v-core at 1.60V at 3.83Ghz but not stable on my rig...

The OS doesn't boost the performance of the CPU. It might perform better, for example be coded or optimized so it runs faster on hardware. but it doesn't "boost up the performance".
