post #1 of 21
Thread Starter 
im looking to push my 2500k to 5ghz did a 1 hour prime blend at 1.5 v bios seems to be good should i go for a 8 hour blend my vcore at load is 1.452 i should be fine priming as long as it dont go above 1.5 load yeah also is it ok to got above 1.5 in bios???

you forgot to mention what speed the cpu was doing when you were running @ 1.5v

If you were using 1.5v for less than 5ghz i wouldn't push it further. 1.5v in bios is fine but you need to make sure it does not go much more over that while under load iin prime

Blend is crap, do large ffts and let it run 12 -24 hours. It can take blend up to 48 hours to work the cpu hard enough.

You mean small fft's, much more heat and stress produced

Sigh, don't use Prime 95. Look at Intel Burn Test. You wont have to run for 12-48hrs with IBT. Download IBT and run like 20-40 runs on maximum. More runs the better.

Prime 95 x64 is just fine. We could battle all day which stress tool is the best.

My thoughts, you want to make sure your overclock is TRULY stable? Use all of em!! I used to rock both Orthos runs and prime 95.

Small FFT is only good for finding out if you're going to crash from the CPU getting too hot for the vcore it's under.

Blend is good for determining if the overclock is just unstable, regardless of heat (unless cooling improvement is drastic). Passing Blend but not small FFT's means you need to improve the cooling. You can often get away with running games just fine if blend passes but small FFT doesn't, as the temps may be up to 15C lower. Passing small FFT but BSOD under blend means not enough vcore. Passing small FFT but getting roundoff errors on blend, usually on ALL threads, is a RAM problem. Getting roundoff error on one thread only, instead of a BSOD, is rare with this platform but is usually more vcore.

48h of prime95. Do you guys really need NASA-stable processors ? I mean, i find a voltage that won't crash my pc in the first minutes of testing, and let it like that for 40minutes.

Never got a BSOD in 2 months. Just a tought of mine, sorry for disturbing,

Also OP, 1.5v is too much, just get some benchmarks and let it under 1.4v for 24/7. I **** my pants when i wrote 1.52v in bios to get a cpuz validation at 5.5, but you want 1.5 for 24/7, with quite a few chips degrading at that voltage. Well, you money, your choice.

Excuse-moi for the offtopic.

So far there's been like 1 case of a chip degrading at 1.5v lol
