Phenom 9950 Overclocking

[Chicken Patty]

Hello,

I want to create this thread to post a few results of my overclocking experience with my 9950. Please feel free to post yours up


To start off, default settings: all runs done with memory at spd settings (5-5-5-18-24)



2.8 GHz


3.15 GHz


3.4 GHz

[Chicken Patty]

here are some 3dmark 06 runs

default settings:


2.8 GHz


3.15 GHz


3.25 GHz

wrong pic for 3.4 pi run but i like the low volts on >3.0

Hey Chicken Patty.. Dude.. you got 2 thread w/ the same name. It will be a bit confusing to understand this is your result thread, and the other one are your questions.

damn man, I didn't realize that. its 1:40am, im sleepy lol. Is there a way to rename it?

[TiTON]

No problem dude. I am sitting here waiting for my SPi32MB to finish running on my 9950.. so I am just reading threads right now. Drop a PM to one of the Admin or Mod.. i sure they can help you out. I am not sure if there is a feature / option to change your own title, but maybe someone can confirm.

you know any mod or admin I can contact about this?

also Chicken dude please could you use thumbnails for these large pictures??

They look good on my 24" LG...

[Chicken Patty]

also Chicken dude please could you use thumbnails for these large pictures??

will keep that in mind next time. I'm used to other boards that automatically resize them and then you clock them to make them larger. Sorry bro.

everyone talked about everything except his results .. no one said a thing about his results, all you guys did was pointing fingers at him.

chicken patty, nice results ..the 9950 seems to be a true competitor for the q6600

[roofsniper]

well what i like about the results is how great of an impact it makes by just slightly overclocking the cpu. this is 3dmark and real games probualy wouldn't have as great of an impact but it really shows something. 700 more points from 2.6ghz to 2.8ghz in 3dmark.

Thanks dude. I dont know yet as I have not tweaked it much but my 9850 was a really good overclocker, I think i Just abused it too much before I got to do any real testing with it. This chip doesn't seem to be as good of a clocker, but like I said, still testing it, I just got this one today, I returned my first one.


Anybody know anything about this stepping?

THanks, I am trying to get it stable at over 3.3 GHz, see what scores I can put out. I know at 3.4 Ghz the time it did pass the cpu test it scored 5004

[Chicken Patty]

heres a run at 3.3 Ghz with mem at DDR2 1066, 5-7-7-24, imma try to bring down the timings and see what i can do.

good job chicken patty.

here my super pi that i ran recently
http://www.hwbot.org/result.do?resultId=778801
22.734 is best so far , need better cooling before i push harder
3d06/ 17191
http://service.futuremark.com/compare?3dm06=8165439
my cpu score seems off a little, cant seem to get real high mhz and keep it stable in 3d06,3d03 works better

thats a great SUper Pi run, however the score in 3dmark does seem to be off, at 3150 MHz I did 48xx in 3dmark 06 as far as cpu goes.

Question...

... what do you guys consider a safe CPU NB voltage? Also for the NB core, Hyper transport and SB???? I'm not clear on these yet, so I try to keep them low so that I don't accidently go too high!!

[vcp-cur]

my s939 x2 4200+ @ stock with 1gig ddr on a dfi sli-d nforce 4 .. i had nothing to do, so lets compare

not bad considering its stock clocks.

What are you waiting for to overclock ??

[Chicken Patty]

i'm having a super hard time to get this thing stable at anything over 3.3 GHz. Any suggestions?

[FlanK3r]

U can try compare Cinebench and effect NB at one frequency CPU (CPU about 2.6GHz, NB from 1800, 2000, 2200, 2400MHz)

I've been thinking about that too. i want to start some testing to see the effects of northbridge speeds and acc settings with the cpu set at say 3200 mhz. what do say chicken patty,its your thread but we could probably all share some useful info. i do want to try spi 1m and wprime32 and maybe a bench called geekbench(good multithread bench that seems to push a phenom).

Sounds good to me, give me some ideas for the bechmark. I'll d/l it now and when I come from the gym later I'll go ahead and start doing some benches.

I dont know what type of cooling you have but 1.35v- 1.4v for CPUNB can help stabilize things when running Higher NB..

Also if your Mobo has a CPUNB to SB voltage setting (this is for the comunication from CPUNB to SBchipset/Memory)
You can run this around 1.3v-1.325v with stock NB/SBchipset cooler.This helps keep the Ram stable and allows Higher Ram freqency and Tighter timing as well..

little things count with Phenom for Stable clocks. NB @2400mhz is good all around freqency..2600mhz and higher require real good cooling especially above 3.3ghz..You can usually clock Higher CPU with Less overall NBfreqency above stock paramiters..

Ive found,,
Stock CPUnbvolts = 1.3v up to 3.2ghz and say 2400mhz.

3.2/2000-2500 with 1.35vCPUnb
3.3/2000-2500 with 1.36vCPUnb
3.4/2000-2600 with 1.36v-1.4vCPUnb
3.5/2650-2700 with 1.55vCPUnb(max volts) My max stable.

By looking above ,, 2450mhz at any given CPU freqency with minamal xtra volts is ideal..

Of coarse this was with SB600 The Volts will be about the Same with 9950/SB750 for CPUNB..The CPU is main factor for NBvolts..Now a 750chipset( CPUnb to SBchipset) will be a little lower because the SB750 does a better job.

Hope that made sense..
Your Cooling will determin the overall Oc.
I just Try to find Max CPU clock @2200nb before raising the CPUNBvolts.. More CPUnbvolts will allow the CPU to Clock higher...Raise the CPUnb and Scale the Volts in Slow increments to find its max. Then Turn the NB back down to say 2200mhz with the Higher Volt setting.

Next try rasing the CPU clock Higher while keeping the CPUnb @2200mhz. You probally will be able to hit 3.4ghz no prob. For me to achieve 3.5ghz i have to run CPUNBvid @1.45v+ and above 2200mhz NB or 3.5ghz wont work. Each chip is differant. Ive found the Higher the Phenom goes the Nb seems best when raised a little above stock ,,Goes in hand with the extra CPU clocks//CPU performance.
