i unlocked my 4th core does that mean its not faulty?

post #1 of 28
Thread Starter 
does the fact that i can boot into windows and do like 90 processes plus youtube+OCN+ xifre mean the 4th core is not faulty?

what i mean is wouldn't a faulty core cause an instant BSOD?

Maybe.

Did you stress test it, I am sure that a few hours of p95 would tell you if that core is truly stable. If it is not, just boost the voltage to the core and try again.

I'd test it anyway. You don't want to risk corrupting files or getting a bsod when you're in the middle of something really important.

Watch out, that motherboard has an uncooled 4+1 power phase. Unlocking and overclocking could mean death for your MOSFETs.

No it does not necessarily meant it is not faulty, but you have a good chance of having a usable core. I can unlock my 4th core and 6mb of cache and run benchmarks and use my PC normally without any problems. Yet it produces errors in Prime95, LinX and Intel Burn Test within a minute or less.

So I locked the 4th core but left ACC on to keep the 6mb of L3 cache; which is stable. I have an Athlon though, you have a Phenom.

I would seriously prefer testing it and being sure it is either stable or isn't, then trusting it to random chance and prayer that it doesn't crash out on something vital.
P95 will let you know if you are good or not, if not, increase the core voltage a touch and try it again.
If it doesn't crash immediately, chances are it can be made stable. Pinning down exactly how much voltage it will take is what testing will do for you.

quick test. Run a program, a game, and set its' affinity to that core you unlocked. If the Program fails then you will know, usually without rebooting windows as well.

Dont need to stress test for XX hours just to see if the core is functional.

I have the same motherboard, admittedly it's not high end, but it can take a bit of punishment.
But OP, stress test it to make sure; Prime 95 etc. for a few hours.

I had a 550BE I could unlock all the cores and it would be stable in windows at 3.3GHz stress test for hours, however after it had been shut down for a while it would BSOD on windows boot screen, so left it as a dual core and OC'd it to 3.6GHz
