How does multiplier locking work?

[coaiti]

I have heard that you can change the multiplier only to have the cpu ignore the change... is this how it works? also a random question: why do u need to "burn-in" ur cpu when u increase the voltage?

Unfortunately no one knows on Intel chips.......otherwise we'd all have them unlocked and oc'd. Yes, if it's locked (which 99.9% are) changing the multiplyer on the board or in bios has no effect.

There's disagreement what exactly it does or if it even works. I swear by it, other's say it's bs. No one knows exactly what it's doing other than stressing the CPU, kinda like a new pair of shoes being "broken in".

I have found that burning in does work but the impact varries from chip to chip. That 99.9% of Intel chips haveing locked multipliers is probably too low a number Shadow :) as "Confidential" chips (as they are known) are truely one in a million.

As far as burning in is concerned I don't consider the "theory" about the chip being broken in like a car engine or pair of shoes, intel burns the chips in for a long time before they go on sale to make sure they aren't going to fail, I won't dismiss that burning in has an effect, but I think it may be due to something taking place on the voltage regulator module on the motherboard which is why I surgest setting a low speed (for low temp=low resistance) and high voltage.
