Dude dual prime stable means a lot longer than 35 minutes, try 8hrs prime at least. nice chip those are been reported with very good overclocks over xs forum as well.
good luck

I see loads of people on these forums with huge OC'd.
I'm talking 2.8ghz on air.
Out of curiosity do you guys run prime95 for longer then say 6 hours?

Tried 2.79 at 1.425v overnight but one core errored after 6 hours.
Probably gonna stick with 2.7 or whatever I can get from stock voltage.

Prime stable past an hour is so useless IMO. I don't see much difference between 1 hour, 5 hours, 20 hours... it's going to fail eventually. The thing is, when prime fails after the hour point, it's pretty much due to heat. Nothing else gets your computer as hot as running dual prime95. So while prime will make it eventually fail from heat, nothing else will. That is what i've encountered. After about 40 minutes of prime, it's pretty stable to me, because if all my games run well, then it's stable.
I'm giving my professional opinion based on the 18 or so AMD 64s i've overclocked on all kinds of air, water, and phase change cooling, having run Prime95, SP32M, benchmarks, games, and daily activities on those many processors at many speeds and voltage combinations. You can run dual prime95 for days or whatever... i spent my money so i could run Rosetta and games, not Prime95...
My point is that everything is less stressful than prime pretty much... Rosetta included. Today a guy told me that Prime95 fails on his computer almost instantly, yet it's been running Rosetta for 3 days straight. Only a few stress testers can equal it. CPU failure is due to heat. We know this - think phase change cooling - same voltage gets you more Mhz, more Mhz requires less voltage. If the CPU errors out when it hits 53c, and it only hits 53c after 3 hours of prime on a hot day... then nothing else will make it fail. I especially noticed this on my CCB1E 0550VPMW. The AMD CPUs with coldbugged memory controllers (Bx where X >= 1) tend to be very temperature sensitive. At every voltage setting there is a key CPU temp where anything over that temp fails, and i found that only prime, not my normal activities, would hit those temps.
So say it can prime at 3 Ghz but then 3.02 fails right... load temp is 46c say. I load up dual Super Pi 32M and it only loads at 41c, and it completes at 3.02, even 3.03. I open the window to the room so that Prime95 only loads at 41c - and it doesn't fail at 3.02 anymore. It only fails because it gets hotter than everything else.
So, i could clockgen to an unstable spot, where Prime95 would only run for like 5 minutes. Most people would call that very unstable, but it actually runs all windows stuff fine, i'll leave the computer on overnight at "unstable" settings and it's good. You have to think outside the box, prime isn't everything.
To the OP - sorry for the hijacking. 0608MPMW is a great stepping, 3 Ghz on air is nice and above average.

I do not think a discussion on Prime 95 is hijacking his thread..as he was running 3.0 GHZ at lower vcore but failed prime95 so he upped the vcore to pass prime
I had several systems including a P4 2.4B@2.9-3GHZ that failed prime 95 in seconds ...but never crashed or failed any game, encoding(even after 4-6hrs) using crappy PC2700 ran running at PC3200...so I agree Prime can be a measure of stablity
I was more interested in your experience..My last 3 setups..2 venices and 170...all were prime 95 tested and they ran smooth...so I used this as a stablity benchmark for me...no one else

This stepping seems to be pretty awesome. If I order a 165 now (from Monarch or whatever), would I have a decent chance of getting one of these?
I'm not sure about that. My last processor actually passed 12 hours of Prime small FFTs (I also ran six hours of Memtest) but was regularly crashing in an old DOS game until I backed down the overclock slightly.

Hey i'll trade my CPU with you! I have a... Well I just sold my proccessor, but I'll buy a opteron 144 and trade with you. LOL.
update on mine...again since my system is an HTPC in the living room, I'm more inclined to see what I can get around the 1.35-1.4V area with CnQ (those voltages also happen to be the max VIDs you can set with RMCLOCK also). Welp after resolving my memory issue (gonna also need a new PS soon ), I'm now prime stable at 2943 @ 1.40V!

btw> I use Prime primirarily because it is the universal accepted conventions to test "stability". Although I can run my other apps / games fine, even if Prime fails, it still irks me that there is a somewhat finite chance still that somehow in some certain situations, my system can hang up (would be quite embarassing if it BSODs during a movie playback in front of friends), so more or less i use it as a baromete to increase my own confidence and tweak accordingly. THis is not to say one way or another is wrong, but rather what I USE. YMMV

Now Dual Prime 5.5 hours stable at 3.0GHz 1.47V:

Will try to bump down voltage later, since I don't like temps dwelling above 50C.
