Anyway, Im not for overclocking yet because getting this chip over 55C scares me. i clocked it to 3.4GHz once, and it was at about 53C idle, and its stock cooling, so I have no idea how you got yours (Thread owner) to 3.95GHz without it turning into molten silicon. Im coming from a Pentium 4, so this thing is fast enough even at 3.2GHz, and I'm like OMG *hair blown back* this is fast.
The "B" stands for the production code of the chip. Let me put it this way, AMD produced a bunch of chips, all marked with a specific code name. Now take 4 quads for example, 3 out of the 4 quads passed AMD's rigorous quality checks while one didn't (or maybe it was perfectly good but AMD decided to sell it as a dual/tri in order to meet demand). So the one's AMD decided to sell of as quads had their code names changed (for eg 945, 955 etc). The other chip AMD decided not to sell of as a quad but as a tri just had an overlapping code name put over the original (like pre-unlocking my chip was the X3 445 when it was actually based on the Deneb die). Once i unlocked it, the code reverted to the factory-default one which AMD had marked it with in the first place.
I'm not running my processor @3.95 Ghz at the moment, not on the stock cooler atleast and till i get the Gigabyte 970A-UD3. Right now i'm running at 3.5 Ghz and idling @ 44-47c + i've undervolted the chip down to 1.25v to keep the temps in check (The default Vcore went insanely high, all the way to 1.4v which wasn't needed really
). It's completely stable topping out at 63C
EDIT: Notice how the TDP's gone down by about 10W as a result of undervolting Edited by PunkX 1 - 11/24/11 at 1:41am
