How to strengthen a weak core? is it possible?

[demonbane23]

I am currently in the process of finding my max overclock on my new rig in signiture,,, and seem to have hit a wall around 2.68 - 2.7 ghz,,, I can get core 1 to run prime stable Large FTT for 10 hours just stopped it myself while core 0 only ran for 1 hour and 30 mins and then failed on rounding error,,,, this was at 2.68 ghz,,, and some new tweaked settings,,

Is this that my CPU cant handle it or that I need to burn in core 0 ,,, ???

Is there anyway to strengthen this core,,, why can one core handle the overclock but the other cant,,,, anyone find any techniques that work?

The only things you can do is raise vcore or try to burn in the proc. Burn in the whole proc, not just the bad core.

What voltage are you running at?

What voltage are you running at?

Right now im running at 1.58 volts and 2.88v on my ram,,, at 2.6 ghz in doing another attempted burn in,, up to 8 hours dual prime stable so far,,,,

I can run stable at like 1.475 for dual prime at this speed but I forgot to re-lower my vcore when I changed my speed,,,

At 2.68 or 2.7 I have one core that runs stable for 10+ hours but the other core fails after an hour or so at those speeds,,,,

To burn in do I just leave this running on 100% for a long long time like 19+ hours?

take the IHS off

take the IHS off


taking the IHS off just gets better heat removal from the chip,,, the water cooling im running is keeping the chip cool just fine,, how would taking my IHS off make my core more stable,,,

cooler = more stable.

give weaker core more steroids... :D just joking.

You have to give to CPU more voltage and then burn it. But OC will stop at some point, no matter what Vcore will you give.
And with cooler CPU, it will be more stable and you can OC it a little more.

thanks for the info, and the link I read through the thread and it seems promiseing,,, cant wait to get home and give it a whirl later tonight,,, between work and commuteing I have a ten hour day so i can even leaveing running while im at work tomorrow should be easy enough,,,

thanks ill give it a try

Well after 1 night of burn in I managed to get the weaker core to run 3 and 1/2 hours of prime before failing at 2.69 instead of the old 45mins-1 hour,,, not bad,, even though the other core runs 10+ hours , ill give it another burn in tonight,,,

also just curious but how do you use CPUburn for both cores,, once I start one isntance I need to start another and then set affinity and it lags like hell because then one core is being attempted to go like over 100%
