Phenom 9950 overclocking

[Chicken Patty]

So far here is the best with my 9850BE and my 9950BE, still working on the 9950 so give me some time. however notice the voltage it took to run 3.55GHz on the 9850, and look at the voltage it took to run my 9950 at 3.4 GHz, I miss my 9850 just for that:


9950 @ 3.45 GHz


9850 @ 3.55 GHz

Well thats not to to bad hey CP?
i think your rite about taking care of my 9850.... it's been bullet proof with stupid high voltage, hitting 100+c when the pump failed.... i think its like the black 5000 i think thats what it was... i had the 6400 BE and ppl were clocking the 5000 to the same as my 6400.... i think all the 9950 is a +1 on the multi 9850 chip.... hell what 9850 cant hit a single bump of the multiplier?
and your goodies are packed and ready to be shipped out in the morning mate

Hey Brad, what stepping is the 9950 you had or have?

B3 and still sitting in the box lol.... i want to wait to mate it with the 79-T mobo... i hit 3.5ghz with a tad bit of fuc^ing around..with this mobo....

naw it aint bad at all, i just need to work on having it stable thats all.

what stepping does it say on the chip itself for example "0831 CPCW" ?

it says.... MIRROR FINISH lol.... its lapped already.... didnt think to check it out..

i however found that on my rig voltage is the key.... i can use same memory and bus speed settings @ 1.48v and she wont pass prime... if i drop the ht volt down to 1.3 from 1.4v and memory to 2.20v from 2.22v and cpu to 1.3850 she passes with flying colors.. and i have no heating problems... weird hey

hey cp

what does all the acc -+ mean?
oh and congrats w/ the super pi!!!!

hehe yeah bro< i find that somtimes relaxing my voltage gives me more stability. Weird but true.

this is the most important paragraph of the whole article


AMD says that the settings tweak doesn't impact performance and doesn't change thermals or voltages, it simply can allow a Phenom processor to clock higher when overclocking. The BIOS exposes the parameter being changed, which AMD refers to as the Advanced Clock Calibration (ACC) value. Typically this value has a range of -2 to 0, on motherboards with the SB750 that support ACC the value can be set from -12 to +12. Higher numbers should allow for higher clock speeds, while lower values should allow for lower voltages/lower power operation.

When I first got my M3A79-T board that was the article I went to before messing around with ACC as I had no idea what it did.

super pi 32m

well this is what i run 24/7 and for all my benchies.... take note of the NB frequency.... Nice hey!

nice bro, I can't get my NB to run higher than 2500 MHz, I am scared to give it voltage too!. But at 2.5 Ghz it flies. I wish I can get it to run at 2.6 GHz

i set my NB cpu volt to 1.40 volt and im at 1T setting lol..... god i hope i dont cook the nb..... but it's running 36c.... which is totally cool

 

[fullinfusion]

hehehe!

 

[fullinfusion]

check this out on 1T setting and 2500+ NB Freq..... let me know what ya'll think

 

[fullinfusion]

to get high NB freq with your memory id highly recomend ya go into your bios and under memory... advanced.... change

Channel Interleaving
to
XOR of ADDRESS BITS [20:16,9]
that way you free up more in your clocks and ...... well it lets me run 1T mode at the above post shots....
a wise man gave me this tip and im now sharing with all

 

[Hayder_Master]

wow , impressive overclock guys

I shall try that when I get my goodies (you know what I mean). the most I have ran my NB stable was 2515MHz i think.

3.4 Ghz super PI 32m

 

[fullinfusion]

wow , impressive overclock guys

thanks man.... we try our best

Its not fair you are having all the fun, I threw my 9950 (140 watt) into a Biostar 790 GX with a 3870 X2, Here it is stock.

Did I do the super Pi right? (first time using)

umm do the 1m calc and show cpuz like this....

@cp i just noticed that i am +.156
