The 3200+ I had was pretty crap when it came to overclocking (it could do 2550mhz, but needed 1.6v to do it). So I am absolutely floored by the abilities of the new chip.

Right out of the gate I hit 2.8ghz (255HTT) with stock voltage and a XP90 (with 90mm fan blowing about 60CFM). I've settled on 2860mhz right now with a 260HTT, still stock voltage (memory running at 216mhz). I know this chip still gots some headroom, and I could definately hit 2900mhz at stock voltage. The fact is, I am certain I can drop the voltage down .025 right now. Gotta test I bet this chip would be a champ with some phase change cooling and 1.6v

What's the record overclock on stock voltage for this chip?

NOTE: Pic is after 1 hour and 30 mins of Prime95
my friend my opty can go to 2.9ghz with stock voltage on my old asus mobo
yeah yeah...

On stock voltage, I couldn't get mine past 2.8GHz. I upped it to 1.6v for a brief period of time, and I hit 3.1 (although I'm pretty sure it was unstable). Somewhere around 3.1 is pretty much the max for this chip. With a 1.85 vcore, I know it could be pushed past 3.5 or so, but that would basically be a suicide mission. So, as far as realistic overclocks are concerned, 2.8 is probably right about where you should be unless you want to invest some cash in good cooling.

The new Sandys are beasts. A great many of them have gotten 3Ghz + on air.

I've actually dropped the vcore down to 1.35, and just started up a prime. Going to see how long it can go

Well, 2860mhz at 1.35v would fail in Prime after 50 minutes, BUT it passed 2 hours straight of 3DMark2001, and passed the OCCT 30 minute test. So I'm satisfied and will leave it at 1.35v. I don't really care that Prime failed.

I would care about prime. If one thing fails...then that means a game could fail, or a photoshop session could fail...something will fail eventually.

I'd bump it back up to stock voltage...and prime for 8 hours to check stability

Ya I agree with sid. I find if prime fails after a few hours, generally games or other aps will crash within an hour or two.

I go with Nick for his system since he is happy with it and in the final result that is all that matters for him.

For myself though, I want to be prime stable with 2 instances for ~8 - 10 hours. I run my machines 24/7 and all events are logged so that I can interpret any instability events. For me that is important. It is not just stable for so many hours so for myself it is system stability overall 24/7. One needs to remember that bit flip errors will bring data corruption that in time will slow a system down and cause instabilities that the person then often blames on other events.
