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?

only way is to add more voltage.

There are some folks that subscribe to the burn in theory...

yeah I was reading over on xtremesystems of some people having sucess with the burn in theory,,, showing some significant stability gains,,, I guess it wouldnt hurt to try ,,, I just dont see how it works technically...

The burn in theory kinda reminds me of the old car theory. The new car performance doesnt really kick into prime until you get past 5000 miles on it or so.

the reason why one core will fail before the other is because not all silicon is manufactured exactly the same. even the slightest variation can change the max frequency it can run with the given vcore.

Burn in might work, but I've never had it change results very much.

reaching a wall around 2.68 is hardly waht would considered "weak", it seems that most hit their wall around 2.6-2.7Ghz, while some few can push it further. AFAIK the only way to increase stability is to increase voltage, but I would serioulsy consider if another 100Mhz would be worth adding .2V if not more.

thanks for the replies,, im going to give it some more time tweaking,,, going to burn it in and see if I can lower the volts or get some more out of it,,, if not id be more then happy to settle in stable around 2.68 ghz,,, I was just wondering if anyone here had any experiance with burn in,,, supposedly someone else stated the purpose was to heat up the silicon and get it to resettle but i dont know if i can buy that
