i7 5960x good overlock?

[shadowman007]

Right finished the Asus RealBench stress test for my i7 5960x   run for 8 hours (this is the max duration available) "Stability Test Passed"  overclocked to 4.5GHz (125MHz x36) at 1.25 volts or to be exact 1.256250 is this a good overclock for this cpu at these volts? I did try 4.6GHz at 1.30v but within 30 minutes got "instability detected" message. (NO BSOD)  Even the temps were going over 80c (with a Corsair H110) so don't know maybe when i custom water cool it might become stable lower temps?

that's pretty good since the stock speeds are 1.0+GHz lower. And it's got 8 cores to cool.

That is a solid chip, a keeper.

Also had another question in regards to the CPU strap and BCLK frequency which is currently at 125MHz can bringing this down to 100MHz effect in anyway? Currently for 4.6GHz overclock it's 125x37 which is 4625 but setting to 100 becomes 100x46 which would be 4600 maybe having that 25 taken away can make it stable?

You usually get the highest overclocks with a mix of BCLK clocks and mulitplier clocks, but since each chip is different you'd have to try yourself to see, but I doubt you'd get any better than you did. Did you go for highest multiplier clock and then highest BCLK seperatly and then combine them into your highest overclock?

Hi, all I have done so far was set the cpu strap & bclk frequency to 125MHz and times that 125x36 =4.5GHz have not tried multiplying it by 100 yet is this what you mean?

Yeah. Most overclocking is done with only the multiplier (your 36x) and advanced users sometimes overclock the BCLK as well for even faster clocks. You are at the limit of what your cooling can do so be careful, but if you get 4.5ish by doing 100x45 then you can raise the BCLK slightly to maybe get 4.6 or 4.7 at that same voltage. Already looks like you got a great chip, but you'll need more cooling to push more voltage into it.
