i5 Overclock

1 hour is not stable :confused:

I only ran for a quick 1 hour, so I can do try a long prime test on the 4.6, 4.8, and 5.0 as I already done 1 hour on 4.2, 4.4 because my other old chip failed BSD in less than 30 mins on 4.2 and 4.4.

Running 4.5 GHz at 1.24v all looking good! My new batch number: L040B354

yeh, but saying it can do 4.4GHz at such low vcore with only an hour testing is missleading. i can probs get mine to post, and if i do enough runs on prime get a good hour before BSOD, with a lower vcore. so i wouldnt say thats a stable vcore at all.
 
Like I say, I will try 4.8GHz for 12 hours and will post back with a photo but just a quick test to start off compare to my old chip cannot handle the same setting as this new chip but my old chip need more vcore but still getting BSD.
 
mine did 50 runs of IBT @ 4.8GHz 1.39v. so its now a case of going down in vcore until it fails. but i know my chip is good for @least 4.8GHz staying within the 1.4v 24/7 boundary.
 
Which one is best to start off IBT 100 runs or 168 hours prime blend for my 4.8GHz at 1.33v, so far on my new chip 4.4 all the way up to 4.8 (no BSD yet) :)

Re-Edited: Now starting prime blend test for my 4.8GHz and leave it running until next wednesday 27th july. If it passed then 1.33v is unbelieved for 4.8GHz, I will be a happy man on this earth! :)

IBT runs hotter and finishes quicker, so start with that.

You only need to do 20 passes of IBT bulldog - if there's a specific IBT related stability problem it should have routed it out within 20 runs (if it's set up properly).

I would leave the extended stability testing to prime - although 24 hrs again shoud be suffice, if you want to be really thorough.

As mentioned before - the all important test, after stres testing, will be the coming days/weeks in day to day usage.

But if you do start getting BSODs after all this testing - don't give up as your initial fidings seem to indicate that your 2600K would only be a tweak away from gaining 24/7 stability.

i failed IBT on run 48 :p would aim for 50 runs to start with, then some general everyday use, then an overnight prime, then some general everyday use, then maybe a 10 run IBT, then some everyday use, then a longer say 24hour prime. if it manages all of that, then i would say then until it BSODs in everyday use you are as stable as you can be.

I take your point - as stress testing is a very personal thing and one mans stable is another mans 'just getting started.'.

Although, IBT is brutal and would say that after 50 passes your CPU was probably on its silicon knees begging for mercey.

maybe :( but temps were ok, so i was happy :) i think the only real way to test stability is to use the pc. yeh it might do 3 weeks of prime testing, 1000 runs of IBT and 3 days of OCCT without problems. you then open IE9 of FF and BAM!! BSOD!!!!!

Don;t worry, my comment was tongue in cheek - although it probably did sweat a bit ;)

Totally agrees with this, stress testing is a great early indicator of an unstable clock - the system will always have to ultimately prove itself in day to day usage.

But, with a combination of IBT, prime etc - set up and ran properly at least you reduce the risk/likelyhood of the dreaded BSOD...
 
mine will go through some intense video converting tonight, thats generally what causes BSODs for me if im going to get any. without your adivce though plec, i would still be sitting @ 4-4.2GHz with my old cooler. the SA is an imense cooler and is a must have. although i can still have up to 11c difference from core 0 and core 2 :(
