With Sandy Bridge You want D1 Stepping, not the weaker D2 for ocing. - Page 9

post #81 of 89
I also see a lot of people running 80C+ with a less than 1.5v.

Not sure if it matters, but Intel states 72.6C on the Tcase.

"It can do 5GHz on air" translates to, it runs when it's over-heating and people have no idea they're seeing thermal throttling. At which point after a few months of running over 1.5v on air cooling the chip dies.

That's my best guess anyways.

I definitely wouldn't be comfortable running 1.52v (I dont care if Intel says that's the max safe) on SB; you have to remember voltage tolerance decreases as you overclock. If 1.52v is safe for stock that does not mean it is safe for lets say 5Ghz.

Personally I'll continue to go by temps more so than voltages.


I've never had a problem overvolting a cpu so long as my temps were still good.

Can you even find an i5-2500k with a D1 stepping anymore? If so, where would be the best place to buy from?

The myth has pretty much been debunked, the highest overclocks for 2500k & 2600k are all d2 stepping.

woof, hell yes.

I saw the first original post, and I checked my CPU-Z. Obviously, mine is a D2... I was so bummed lol.

Not that I REEEAAAALLY need 5GHz on air but, well. e-peen or w/e

yea you really can't do anything without CPU PLL Overvoltage and Intel made sure it wouldn't work on D1.

Dunno about D1 Stepping but i'm pretty happy with my D2 2500K, It runs at 4.606Ghz with 1.22v 12 Hours Prime95 stable biggrin.gif
