Phenom 9950 overclocking

[Chicken Patty]

you guys are too much.

Its true man,
the way I see it we are just 200mhz behind the p2's. So if i'm at 3.3ghz its like having a PII at 3.1GHZ

PI vs the PII, there is no comparison mate.... trust me.... one thing is the chips memory controller is way more aggressive..... my shitty tracers on the 9850 turned out to be killer sticks on the PII 940....

 

[fullinfusion]

Just a slight note for those upgrading to the PII..... in the bios for the M3A79-T mobo use the 0603 bios.... its the same as the 0702 bios but its more stable.... also.... under the cpu tab in the bios make sure you keep the Micro Code Validation enabled..... its not like the PI's where it helps clocks..... Leave it on! when its off i can run stable at 3.726GHz but when its on i run stable at this...same voltage

This morning I was able to run @ 3.4Ghz w/ 1.55volts but after almost 20min of the AMD stability test I started getting random errors in Windows so back to the drawing board. Right now I'm @ 3.3Ghz @ 1.4675 volts and ACC set to 2% so about 1.488 volts.

did you try acc higher for 3.4 GHz?

well i have my 9950 running at 3.3ghz now at 1.45 for vista ultimate x64 but for xp 32bit its 1.43 with acc set to auto, max temp 45C idles as low as 25C and this is with air cooling, gonna push it further when i get a better psu,

very good so far Welcome to TPU. Keep us posted on your progress, watch your temps and dont be scared to give it voltage, these chips love it.

 

[kenkickr]

did you try acc higher for 3.4 GHz?

No, I have not. I've been to bus playing MLB2k9 but maybe tonight or tomorrow morning I'll play with it some more.

 

[King_Jay16]

well i lower my HTT to 1.8ghz and up the CPU NB to 2.4ghz and now have my ram running at 1067 while still at 3.3GHz, and running real stable.

very good, try setting HT back to 2.0 GHz. If you plan on going over 3.3 Ghz, leave it like that for now, it helps with stability to have it at 1.8ghz.

 

[King_Jay16]

yea i know thats y i have it at 1.8 it makes the system stable

 

[Chicken Patty]

yea i know thats y i have it at 1.8 it makes the system stable

glad you do Keep us posted on your results.

 

[King_Jay16]

yup, gonna put in my his 4870 1gb now

CP you have any idea the max Voltage this chip can take, I mean for a suicide run?


Im thinking 1.65V, what do you guys think?
Honestly IDK if it dies either, lol. Want it to be stable to do few 3.6GHZ runs xD

Just wanna take the top Phenom 1 spot on Wprime already..

I pushed 1.68v on mine

Brad (fullinfusion) did like 1.8 and so did cdawall, hope that helps lol

Nice, IDK 1.8v is kinda like premeditated murder on the CPU, lol.

I''ll push it till 1.7v see what happens....

1.7v still scares me lol.

 

[3dsage]

Well, I didnt go for 1.7V. I maxed it at 1.675 and still couldnt get a run in at 17.5X multi .

I have an 0843APAW chip also, I thought these had the most potential.

what were your other voltages set at?

This morning I played some more and was running @ 3.4Ghz with 1.475 and ACC set to 4%. Ran AMD stability test and at around 11min system restarted. After that I wanted to try and see if I could run my ram @ 1200 and with FSB @ 250 system would boot fine so tried 260, fine again, but @ 270 system wouldn't boot. Shut her off and turned her on, he he, and bios post showed the proc running @ 3.57Ghz, multi set to 10 and 270 don't add up to 3.57Ghz...that'd be nice!! This was the same issue I had with the Asus M3A32MVP-Deluxe, at a certain FSB the bios would show some crazy Mhz. Tomorrow I'm going to play some more but after playing around I can get the ram to run @ 1157 w/ 5-5-5-18 timings @ 2.12 volts.

I remember once I swapped in my athlon 64 to play around with it, and when I put my phenom back for some reson it detected the settings of the athlon, and the BIOS showed CPU running at 3.8ghz doubt it that was true, even for a sec.

what were your other voltages set at?

ACC +4 (all)
NB VID 1.45V
NB 1.45V
MEM 2.2V
I dropped HT to 1.6 and NB multi to x10. What do you think? I'm on Vista 64x also.

I found sometimes dropping my HT before 1.8 for some reason cause instability. Perfect HT for overclocking with my setup was 1.8. no instability, and helped keep the CPU stable to find its max.

I've been considering going to a water cooling setup but for a cpu block, radiator(even though I have one I'm thinking of a double loop) 2 3870x2 blocks, pump, and money to make a waterfall reservoir i think I'd be better off just getting a Phenom X4 AM3 chip and throwing it in my system since they OC pretty well on air, and I get the 6mb of L3 which would benefit me since I do alot of video editing.

 

[3dsage]

Yeah I've read that around also. I'll give it a shot.

I know Meizuman got his to run 3.5 with the same board. Except he was on the F2 bios and i'm on f3h.

I hate flashing bioses, I bricked a board before and I dont want to risk it.
