Phenom overclockers. Do they exist on Anand?

[superstition]

Like AMD's other "Black Edition" processors, the 9850 has an unlocked upper clock multiplier that makes overclocking ridiculously, guilt-inducingly easy.

Uh huh.

2.7GHz/stock - pass
2.8GHz/stock - pass
2.9GHz/stock - no POST
2.9GHz/1.36V - pass
3.0GHz/1.36V - hang on Windows boot
3.0GHz/1.403V - BSOD on boot
3.0GHz/1.442V - BSOD on boot
3.0GHz/1.481V - pass
3.1GHz/1.481V - hang on boot
3.1GHz/1.519V - hang on boot

A "pass" means the CPU made it through 4-5 minutes of the stability test in the AMD Overdrive utility.

Hitting the 3GHz mark took more effort and a lot more voltage. In fact, I finally settled on 1.519V at 3GHz for my testing, and even then, the system wasn't perfectly stable.

my latest results, 100% stable, the highest i've been able to get 100% stable.

What's your CPU score?

What are your temperatures and what cooler do you use?

Temp's are close to default, using stock cooler.

Just reporting back. At 2.5, its still unstable. :\ Its NOT 100% stable. More voltage needed, but I'm gonna back off until I get a new cooling solution.

Come on, pump some juice in it. It shouldn't get that hot on stock cooling.

I just got an MSI K9A2 Platnum and an Arctic Cooling Freezer 64 Pro (it was on sale for $20 at Newegg). I'm going to grab a Phenom 9850 when they become available, hopefully in the next week or two..? Anyone know? I'll post my results once I get it and have a few hours to tinker.

Well, after researching, I found some bad news. Unfortunately 64bit OS' cause the most instability on the Phenoms when OC'ing. I'm running Vista 64 and the max I can get is 2.5GHz. Prior to Vista 64 I was running WinXP 32bit and I was able to get 2.7GHz for a couple seconds before it crashed. 2.6GHz was possible but was instable. 2.5GHz was the max stable at safe vcore's. In Vista 64 AND WinXP 64 I couldn't even select 2.6GHz. Instant freezing/crashing. I then found this thread. Sad, but true... if your planning 2.6GHz with a Phenom 9500/9600... run a 32bit OS.

I'll do more testing tonight with my Vista 64 setup. I've yet to really try OC'ing within the bios. For all I know, 2.6GHz is possible but AMD OverDrive may be the cause of the instability? Who knows... overclocking Phenom's is a myth in itself.

That was my idea too, but I would take the 9550 instead and overclock it to 2,9 ghz ( at least that is my wildest dream). I'm still waiting for the intel E7XXX series to see if I can get more bang for the buck with them and change the whole platform. But the cheap quad core upgrade sounds so good.
I guess next week we should see them both in action hopefully.

Any reports as to whether or not Intel chip's overclocking margins are equally affected by operating in 64bit mode versus 32bit?

As far as I know for sure, this seems to be a Phenom B2 issue.

Well the 64 bit operating syste seems to be more demanding for cpus then the 32 bit version. So I guess both AMD and Intel should suffer from an overclocking hit in some way.

Not if the overclocks are stable. All we're talking about is exposing an unstable overclock.

As far as I know, its a flaw with the Phenom B2's only. I've never heard of a Brisbane, Conroe or Wolfdale having overclocking instability caused by an OS.

 

[v8envy]

My data point is for 0 difference in stability of Intel CPUs on 64 bit vs 32 bit Linux -- my quad is clocked as high as it'll go (won't even POST at 374 mhz FSB, 373 is its limit), and has been running on a 64 bit Linux with ~6 virtual machines for about 24x7x2 months now.

I second what superstition said. If your OC is truly stable, 64 vs 32 bit doesn't matter a bit. The 2.6 ghz 32 bit OCs which fail on 64 bit OSes just haven't torture tested their CPUs enough to see the limits with 32 bit -- many people in that thread certainly haven't. They just cranked the clocks, booted up the OS, declared success and were surprised when the thing imploded shortly afterward.

That, or all their ram has some bad bits in the region 32 bit Windows can't get to. =)

Ive run both and have not noticed a difference (32bit ultimate and 64)

Well, after installing WinXP 64 and Vista 64 I can say with proof that WinXP is the better OS for framerates. I lost about 13fps in Crysis with the only difference being Vista 64. I'm not sure why, but its true. I get 37fps in 1680x1050 in Medium in Vista 64, in WinXP 64 I got 50fps. Same exact version and settings. Not sure why?

13fps doesn't sound bad until you put that into context of a % slowdown...37/50 = 74%...a 26% slowdown is ree-donk-u-lus!

Yeah, 26% is a pretty big difference.

Yeah, their naming convention is piss poor. I mean they left no room for any improvement from their original chips. Are they planning on having no higher speed binned parts?

Correct, they aren't. AMD stated there will be no further revisions. It is now rushing to upgrade a plant to a new, smaller process. And to get their next gen up and running.
They only fixed the TLB bug so that they can sell barcelona chips to servers (since its the same core as a phenom).
They are PROBABLY going to rename it from phenom to something else considering all the bad press associated with phenom.

 

[Sylvanas]

Tony gets 3.5ghz on water Phenom 9850 B3.

 

[batmang]

^^^ I saw that thread earlier, pretty impressive considering the Phenoms OC rep.

 

[tenax]

the movie called phenom made for a much better story than this processor
