An overlooked overclocking factor?

Do supposedly good overclocking boards fudge by overvolting the vcore?

Exactly how accurate are vcore readings off the board's bios?

I've seen wildly different voltages reported here to produce the same speed & temps
that simply can't be explained by cooling solution alone.

Take my example:

2 different boards (Abit/Jetway) running CCBBE 165 Opterons at 2.8 ghz, same cooler,
same room, same case, same load temps of 53C, yet one needs just 1.4v to run
stable, the other needing 1.5v.

Can a poor 12v rail off the psu account for the undevolt?

"Yeah, my new board only takes 1.35v to hit 2.8."

Really?

I've seen alot of high temps reported by supposedly low vcores.
 
Different CPU's... just because it has the same stepping, week, and factory codes on it, doesn't mean it's going to clock the same.

Yes, this I understand, but it neither proves or disproves that the 2 cpu's might be running
at close to the same vcore. Short of a multimeter, who's to say?
 
Unless you run the SAME cpu in both boards, there is no comparison....

Indeed, and to take this one step further, certainly no meaninfgul comparison between one person's cpu and another's.

And yet we still do and the posts continue ... notwithstanding all the myriad
factors and variables :)

Then I'll sum it up ... there's no absolutes when it comes to overclocking. But you

Oh, I thought you were asking a bunch of rhetorical questions. Which just in tern makes a useless thread.

Oh right, that's the whole thread.
