Phenom 9950 Overclocking

[Cluster]

Actually, if my math is right, my latency is lower, and my bandwidth is higher.

474 = 237Mhz = 4.22ns(time per clock) x 4 = 16.87ns
610 = 305Mhz = 3.27ns(time per clock) x 5 = 16.39ns

Remember, latency isnt just the clock setting you put in the bios. You have to factor in the time of each clock. Saying CL4 > CL5 is like saying a 11x multi > 10x multi... kind of meaningless unless you know the FSB of each.

I also racked up this too, 5m 42s wPrime1024:


So close to beating the top 9950, if i could just run for 6 minutes at 3.5ghz!

Just need to go a bit colder. Temps were around 19-21c for that run (judging by water temp, which was 6c). Its supposed to go -35c here again next week, so i should see some sub-zero core temps.

Don't know when it was done but AOD 2.1.5 is available now: http://game.amd.com/us-en/drivers_overdrive.aspx?p=1

I seen that, and from what i heard, avoid it. Some how they totally screwed it up. Expecting a 2.1.6 to follow suit in the near future. Seen people posting screenshots of 9950s @ 4.2ghz @ 1.3v lol

The only bug I've found using an M3A78-T is the CPU speeds - for some reason it can't seem to read the right multiplier. It thinks 14 = 15 and 15 = 17. LOL

vCore is good as are the rest of the settings on the Performance and RAM pages. But that's strange enough for me - I'm going back to 2.1.4 that ASUS released with the M3A32 ...

Anyone using a OC'ed 9950 for F@H?

Try unganged mode. Seems I must increase memory speed here to stay in competition.

I was testing a little bit my Cellshocks yesterday..
With AUTO at DRAM settings, I booted at 200 fsb with 533 DRAM Frequency.
My timings were set at 5-6-6.
From AOD I changed them to 5-5-5 and managed to run SPI until FSB 225.When I increased more I got a restart.
When I changed the timings at 5-5-5 in BIOS, my pc couldn't boot and I only could clear cmos to boot.

So, what is your opinion.How your cellshocks are behaving?You think I should put more voltage to them?Are you running 24/7 at 2,2 vdimm??

Hmmm, one thing i try not to do is set the ht ref too much in AOD. It doesnt play well, and its more stable from a bios setting. Also, when moving the htref, i've found apps like cpuz, or anything else that probes the mobo can cause lockups. Its a known issue, not sure that theres anything amd can do about it.

Im not sure what to make of it not booting. What are your volts at now? I can run upto 225(600) with 2.1v. It seems to want to spike after that, and i need 2.24v to hold 233(618). I've had some mixed info as far as what this ram likes. Some tell me lots of volts, others say keep it low. I seem to be hitting a wall with 233 @ 2.24v, even pushing the volts to 2.5v wont get me 234, wont boot windows. Not even with the timings set flat open, 6-8-8-24 or something stupid like that. So im not sure whats holding me back. I've seen these things do 700 with less than 2.5v @ Cas5. I think its something with the board thats holding it back.

I've tried some Cas3 runs, but i couldnt get them much over 420ish. I think they just wanted lots of volts for that, but this stupid board caps the vdimm at 2.5v... its my only dislike about this board. Everything else is great, cpu volts will go to 1.85, nb/sb volts go plenty high, but they cap the damn vdimm at 2.5. I dont get it. I have been itching to pile 3v into these, i've heard they can be monsters with cas3 with lots of volts. And i've got plenty of cooling for them, its -35c here

As for 24/7, i dont use the cell shocks 24/7. 2gb isnt enough, i have seperate 4gb sticks for 24/7.

Here we don't have so much difference.
Mine with 466 Dram Frequency is at 5.49..

Ya, your actually running your chip faster than mine, by 50mhz. Maybe its the difference in the OS? Although i have been told that vista is supposed to be better for wprime, my results are all on a very trimmed and tweaked xp32. I have a new setup in the works that im testing a little later. Running on an xp32 that boots with 29mb of ram used

Personally i never run benches on vista, too much bloat.

Ain't THAT the truth? I've been testing another 9950BE on an M3A78-T running Premium x64 - first time I've used Vista. What a pain! Can't seem to get the thing P95 stable at 3.0 GHz but I've been running SETI x4 for the past 24 hours at 3.2 and it's cranking out numbers like a champ without error. Go figure! Usually I have to turn down a P95 OC about 50 MHz to make it SETI stable but this (P)OS is being a pain.

I'm really beginning to hate Vista ...

[RASTAVIPER]

Guys it's a fact.
Some benchs like Pcmark05 and Wprime DO run better in VISTA.
I have tried both in XP and VISTA and they are faster in VISTA.

So do i get bonus points if i beat the top 9950 scores with my 9850 in XP

[QuietIce]

I think Honda can do that right now ...

[HondaGuy]

I think Honda can do that right now ...

Even on a SB600....

[Chicken Patty]

Even on a SB600....

honda, just to see what you think about it? Why do you think you can clock that high with the SB600? CPU, mobo, etc, what do you think allowed this? Just would like to hear some feedback, its an amazing clock and even more amazing on a SB600!!!

[Cluster]

I think im at my limits with this chip. Every time i push it it seems to do a little better than before. But i have yet to see this thing stable for even 30 seconds at 3.6ghz. Best i've seen of it so far was about 60 seconds at 3585, enough for a SPi 1M + SS then crash. Maybe its starting to succumb to all the volts i put through it, after a few hours of driving 1.85v it seems to like being stable at 1.6. Who says torture isnt effective

[HondaGuy]

Cluster: plug in your PSU straight into the wall, dont go through a power bar, see what you can do then

I have that horse shoe hanging up beside my tower ...
I see most people have 2x2Gb Ram,,,,Im just running 4X1Gb sticks... I was running on air with the Zalman 9700 CPU@3.5 but really couldnt put any load on the CPU. once the temps at load were at 66 only left it at those temps for about 1 min..Then went to H20 and now able to hit 3.7...Soon I;ll be try'n 3.8 . Fingers are crossed...
Even with my old 9600 I was able to OC that to 2.6...My 5000+ to 3.35. could just be my board that Im lucky with....
Just going to put in the Phenom 940 on this board and see what it can do...

i think you apart from having a golden CPU you have a freak of a board dude. Congrats and keep us posted. Can't wait to see what you can do with the 940

I think he's got too much free time ...!

[SkullCracka]

m3a32-mvp i still think is the best am2+ board out there. often over looked becuase of sb600 and its price. but if what were hearing and reading is true sb750 vs sb600 is no longer and issue with PHII. sb750 really only helped bad clocking chips anyway.

hope i get a better chip than my 9850. when i upgrade to PHII later this year.

[mongoled]

Are these the nice sticks you peeps are using getting 600+ mhz frequencies on the ram?

http://www.memoryc.co.uk/products/de...kit/index.html

There is no way I can get close to those frequencies with the 2 x 2GB sticks I got in my sig, was trying to challenge Clusters records today but failed miserably, did manage to get a 1M run under 22 seconds though

http://www.hwbot.org/compare.do?resultId=807324

If these are the right sticks I can grap them and then have another go at claiming VICTORY



This rig is stable at 3.6 Ghz for browsing the web not much more than that mind you, lol

only free time on my hands with just over the Xmas holidays, then back to work it is, damm bills and new PC parts to buy

Dude, I beg to differ. My 9850 was an amazing CPU if you ask me, not the best, but amazing. 3.6 Ghz @ 1.456v, and without ACC it would not go over 3.15 GHz. the phenom II is a new CPU which they will obviously fix many issues that plagued the Current Phenoms. However PHenom II's are still getting higher clocks on a SB750 than a SB600. ACC definitely helps dude.

[SkullCracka]

"sb750 really only helped bad clocking chips anyway." you must have missed that part.

PHII they say will not OC at all with ACC. so sb750 is not needed with PHII. <<< hope that holds true ... still think the asus m3a32 is the best board so far.

just an opinion. its all good.

well I had the M3A32-MVP and I have the M3A79-T, I have both now actually and I thought there was a difference from night and day between both. Of course I think the M3A32 is still the best board, only after the M3A79-T, the little extra features and the PWM on that board is simply awesome.

As far as Phenom II's it is a CPU that is not dependent on ACC (SB750) as much if any at all. If they were still dependant then what would be the purpose of the Phenom II if they wont overclock any better.


About ACC helping bad chips only, well I have not seen a Phenom that does not gain at least a bit from ACC. So does that mean all Phenoms are bad chips?

Of course its all good bro, its a forum, we are here to have friendly discussion and learn.
