Pushing my 2600k past 5ghz

[christee66]

* EDIT to add bencharmark

So i got bored and decided to try to push my 2600k past 4.5ghz last night. It Took me a while but i am up to 5.0ghz and been stable so far. 5.0ghz was my goal and i am happy to have hit it . I would like to share my settings and ask for any feedback and/or tweaks. I realize these settings will likely degrade my CPU and i don't care. It is not an everyday clock i just wanted to try to push as far as i can for benchmarking. If my CPU burns out i will have a reason to upgrade my chip and board. My last test of prime small ran for 1 hour without fail. I stopped it there. Had a max temp over the 1 hour of 81 with average temp of 76 - 78. You guys think i should push farther or leave it alone and benchmark it?

Well there you have it. Any comments or tweaks anyone can think of feel free to post. Im not sure if i want to try to push any further at the moment yet. But if i do i will let you know.

If you're just benching, no harm in pushing the core speed a bit more. Doesn't have to be completely stable for benchmarking, just has to finish the run

Stability-wise, sounds like you're at a good spot if prime's okay for an hour. I wouldn't want to run it at 1.45V if it were my chip, but if you're okay with degrading it Personally, I'd rather sell it and upgrade for cheaper rather than kill it and upgrade at retail.

Nice job

1.45 or less for 24/7 is fine. I wouldn't go over that for sure...
