Hey forum members, I've been following this guide, http://www.bit-tech.net/hardware/cpus/2011/01/07/how-to-overclock-the-intel-core-i5-2500k/4 To give me a basis for overclocking my new CPU. my question is how do I test the clock for stability. I've run intel burns test on very high 10times. Now I'm running prime 95 blend mode, but how long should I run it for?
The longer you run it without errors, the more stable your overclock will be (up to a point). Once I've achieved what I think is a stable overclock, I will tend to keep Prime95 running pretty much all afternoon/evening to test it. So you're probably looking in the region of 6-8 hours of testing.
Or do what I do. Overclock it to where you want it and use it as normal. If it doesn't crash, it's stable enough for me
I usually take this approach as well, but I have to admit it's a bit annoying to have intermittent bluescreens months later while trying to work or play games. Bumping Vcore up a notch solves that issue though.
Pretty much what I do. I will bump the multiplier up to start with 48 and set the Vcore to 1.35v and then see if it boot's in to windows, and if it does I load up Realtemp and Prime 95 and run it. If it crashes then I bump the voltage up and try again and repeat, but I never go above 1.410v on the Vcore.
1.4 is probably my max for 24x7, but I have had 1.52V through mine for brief testing at 5.3Ghz on air, and 1.6V will get mine to boot at 6Ghz under sub ambient water. Very good overclocking chips the early ones of these, some of the later ones can be a bit poo when you want to push it. But 4.5Ghz is definitely possible, and 4.8Ghz is highly likely.
I find that Overclocking these babies I tend to crank it up as far as possible without touching the voltage. Then I push the volts. Then I turn down the volts. Then I realize, sod it, 4.4Ghz @ 1.2-ish is fantastic and just settle on that.
Clock as far as you can on stock volts. Just work up from the 40 multi and run 20 passes of intel burn test Repeat till u get a fail and then work from there if you want more add some volts. Easy as.
I put about 1.525v through mine for 5.2ghz under water and temps remain perfectly fine, but the voltage is to high so I only use that for benchmarking.
keep things sub 1.4 vcore for 24/7. i usauly just prime it for 6-8hrs and be done with it. Have also done what others have done but its very anoying
Once you hit about 4.5Ghz diminishing returns on the rest of the processor. Then again I like low volts.
i got to 4.2Ghz.. using the above bit-tech guide.. it seemed to BSOD anything higher. i will work further at weekend i would like a little more 4.3/.4
There is always some variation of course. I found I can take mine to 4.4 Ghz with no additional voltage, but it becomes unstable at 4.5, so I run it at 4.4.
i used the volts from this thread: i think it may have been a turbo setting i had enabled making it BSOD, so im gunna try again upping.
