Lower voltage required after OC 'burnt in'? (E4300)

[Tooks]

Just wondered if any of you guys had experienced similar with overclocking the E4300?

Basically, to reach 3.2 ghz on my chip, I had to give it 1.5125v V-core to remain stable, this from when the chip was brand new.

I've been running that clock day in, day out now for 12 weeks (although turning it off every night), and a few days ago (although I can't remember why!) I thought I'd try and see if it would still work with lower voltages, as I was a bit unhappy with my temps.

I'm down to 1.4v V-core now, and it's still Orthos stable for several hours.

The temps have fallen from 39c/65c idle/load to 34c/56c.

Has the chip now 'burnt in' so requires less V-core? Anyone else had similar? What's happening here?!

Yeah, never been a fan of the 'burn in' theory myself, hence why I've always overclocked my CPU's from day 1!

I did upgrade the bios on my P5B about 5 weeks ago, but I left everything the same, including v-core, as I thought I'd found where my system was at.

I haven't changed anything else at all, just nudged the v-core down a bit at a time to see what happens.

I'm not complaining, as lower volts has to be better, just wondering why it wasn't orthos stable before, and now it is?

Cheers easy, thanks for the link.

So, there could be something in it, or maybe not?!

Either way, my CPU, with no other changes that I've made, is now running the same clock stable at a lower voltage than it did before.

Clearly, something has changed within my setup, maybe the mobo (although this was some months old by the time the E4300 went in), but maybe not the CPU...

If I can just step over the argument for a moment, yep, there we go....

It would appear from this thread, the linked thread, and some Google searching I've done myself, that this 'burn in' theory is one that lots of people disagree on!!

All I know is, I'm running less volts for the same clock now than previously, and nothing has changed in my system, apart from the passage of time.

I was only asking if anybody had experienced similar in their setups, and maybe if they knew what was causing it!

There is no doubt in my mind that things like my Hi Fi amplifier definately sound better after a few 10s of hours of use, and the manual even said as much. Whether that applies to CPUs or not, I don't know.

Maybe it was just the Bios update that has changed things for the better?

Thanks for the contributions all.
