That is great news, even though his system is not stable at that speed yet.

Tony got his Phenom stable at 3.2GHz & 2.4GHz NB for now, and his Cinbench 10 64bit score is a little higher than what a QX6850 (3GHz) gets. Proof that with higher CPU and IMC clocks Phenom does scale well.

I think if he manages to OC the IMC to 3.2GHz, he would gain another 4-5% extra performance, which would make his Phenom close to Intel Yorkfield performance.

Just a word of warning .... upping the NB/IMC beyond 2.5-2.6GHz generally requires a big jump in volts and equals fried chip!

You might be right about frying the chip, I've read that in a few places. But you know, these are B3 steppings, so they might be able to handle a little higher frequency especially with water cooling.

BTW the 3.5GHz OC Tony achieved had the NB at 2.7GHz.

Heres the results:
3DMark Score - 11230
SM 2.0 Score - 4476
SM 3.0 Score - 4835
CPU Score - 3745

i dunno what happened to my gpu-z window... but the settings are 830/1200.

CPU-Z | GPU-Z | Crysis 1680x1050 Medium DX9 | Riva Tuner

If someone was a Crysis nut, I don't know why that person would use Vista. I gained 11fps going with WinXP 64. I ran the same exact benchmark before going with XP 64 and I got 38fps with the same exact settings in Vista 64.

Now this is just silly. Comparing the best possible suicide OC one person on the planet got with a golden chip to a stock clock Intel quad.

Plenty of people are getting 3.5 and higher OCs out of Yorkie quads without resorting to extreme measures. I've even seen suicide benches at over 5 ghz, which would be comprable to the 3.5 phenom effort.

Even assuming he got his chip stable at 3.5 ghz on water with 3.2 ghs cache/MC, care to speculate how that'd stack up to a Q6600 at 3.6 ghz on air?

But you're right in one regard -- it shows lots of promise for the 45nm AMD quads if those can hit clocks comprable to current Intel chips and have a cache clock synchronous with the CPU clock.

I think you missed my point. If you check the Phenom reviews, at low CPU speeds, say 2.3-2.8GHz, Phenom for the most part losses to Intels Quads, even when it has a 200-400MHz advantage.

But at the speed I mention above, 3.2GHz and a higher NB clock, it is a little faster than a 3GHz Intel kentsfield, at least in Cinbench it is.

Yes it does have a 200MHz clock advantage over the QX6850, but a 200MHz advantage didn't help the Phenom at low frequency speed (check 2.6GHz Phenom vs Q6600 2.4GHz), while at higher speeds it does seem to help

Of course OC results don't compare with Intel CPUs, Intel wins hands down you know.

But you're right in one regard -- it shows lots of promise for the 45nm AMD quads if those can hit clocks comprable to current Intel chips and have a cache clock synchronous with the CPU clock.

What I was thinking too.

Tony got some nice Cinbench and 3d06 numbers out for his Phenom @ 3.4GHz / 2.5GHz NB, check them out.

I'm waiting for the B3 owners for chime in.

I wouldn't call tony's OC a suicide run. Suicide runs often require tinkering the motherboard/ram at a physical level, LN2, and various other stuff so that you can effectively clock the chip @ vcore up to 1.9~2.0v. But this takes time, since error and trial method can potentially kill lots of test subjects along the way.

 

[batmang]

Aight, I'm done tinkering with my 9600. I don't want to or plan to buy aftermarket cooling. I figured I'd try and maximize my setup. No increasing ANY voltage to keep temps as close to stock as possible. I think I've done that.
I have all four cores running at 2.4GHz, voltage of 1.200v (default, low huh?). Video card is at 830MHz core / 1205MHz memory. Here are my results. 100% stable wooooooot, 100MHz OC!

And I'm sure a Q6600 with a 3870 at the same speeds would get higher scores, but I dont care.

 

[batmang]

Another update. Currently at 2.6 at stock vcore.... on two of the cores. 2.4 on the other two.

Why not up voltage a bit to 1.25V or so? I see you are on stock HSF though, I don't know how hot it gets.

Have you tried oc'ing the NB?

BTW I have a Phenom 9500 here I got dirt cheap, just have to wait for the motherboard to come.

 

[RiverRicer]

9850BE, 2.9ghz @ 1.35v, folding SMP 24/7, 50C full load under Swiftech H2O 220, 56C PWM with a 40mm strapped to its ass. Haven't tried to tweak much as yet.

All upping the voltage seems to do for my setup is make the cpu run really hot. I can do all 4 at 2.5ghz but then it will intermittently crash even though it passes almost every major benchmarking test. I'm trying to find out the cause for the instability, it's prolly my generic 585w PSU.

Ordered my 9850 today, I'm looking forward to playing around with it. To tell you the truth, I doubt I'll see much difference with it compared to my current 939 system for what I do (gaming mostly and general use) but you know how it is when you get the upgrade itch.

 

[batmang]

quick update, ran Crysis in HIGH in 1680x1050 with my crossfire setup. Got 33fps. Thats pretty decent.

 

[batmang]

Another update. I'm back to Vista 64 and I'm gonna do a little testing this week. Anyone else have any Phenom oc'ing results?

 

[SlowSpyder]

Best I've been able to get so far is 12.5x235 but the PC would randomly reboot. So, for the time being I went back to 14x200 and it runs perfectly @ 1.412 volts. I'm happy with my temps there, so until I get a better cooler I'm not really worried about going any higher since it's fast enough as is for now.

 

[Extelleron]

My Phenom 9500 is not that great.... it's stable @ 2.5GHz w/ 1.344V and that is where I have it for now. I could probably get 2.6GHz stable but I'm not sure how much higher I want to bump the voltage.

 

[Rhoxed]

Sitting at 3 with stock volts for almost 2 weeks now, time to bump it up again and see if it can handle being idle-stable (benches or OCCT run fine up to 3.15 but idle is usually not stable)

 

[northy84]

i've got a 9950 that i'm running at 2768MHz everyday 1.3V. crucial ballistix tracer running 852MHz 2.25V 4-4-4-12. asus M2R32-MVP is the motherboard. crossfire 2900xt's. my idle temps are 30 - 32C and max load temps are usually 39 - 41C never more than 45C (gamming for hours)

i had this puppy up over 3.3GHz running all sorts of things but the video cards started to bottleneck. voltage was a problem, or lack of, eventually i fried one of my memory sticks from too much volts (tried to hit 1066) the three i have left run fine at 900. but i dont want to kill this mobo as i have read it doesnt fare well over 125W and this CPU is rated for 140W. maybe if i can get an M3A MVP board i'll try some more ot get this stable at 3.3 or 3.5

i had to bring this thread back to life i want to see what ppl have gotten these up to!

 

[thilanliyan]

I've got my 9850 at 2.9GHz on 1.375v on this Asus board I have... but on the Gigabyte board I was using before I had it at 3GHz at 1.35v. I haven't bothered pushing any higher.

 

[Rhoxed]

i have
9850BE @ 3.24 with 1.37V (SB600)
9550 @ 2.85 with 1.30V (SB700)

friend with a 9950BE @ 3.45 with 1.45V (he has SB750 board)

 

[Sylvanas]

Running at specs in sig, 3.3ghz / 2.4ghz NB- I have a thread on motherbaords section all about my OC adventures with Phenom.

 

[SlowSpyder]

For those that have their IMC/northbridge bumped in speed, what kind of voltages are you guys running your IMC/northbridge? I just can't seem to get mine stable even 1MHz past 200MHz. Did you bump your HT voltage at all? I seem to need a lot of voltage compared to most of you to stay stable at 2.8GHz. Seems like a good deal of you are at 3GHz+ with less voltage then I am running at 2.8GHz. Not sure if my chip is to blame, my SB600, or me. My guess is a little of all three.
