Phenom 9950 overclocking

[fullinfusion]

Did you bump the SB a bit?

yeah i did... i set it to the old setting of 1.12v for the sb.... why you asking mate?

 

[merkk]

I think most the guys that are running 79-T are leaving the SB volts on auto . I not heard of them having to mess with the volts on the SB to get good over clock .

 

[Meizuman]

It was just a thought. I saw some better stability on my Gigabyte when I cranked it up. I don't know how that 79-T will do. I have no experience on that board.

i'll be posting in my new thread about the 79-T mobo... since CP is an Intel fan boy now... thx

Please specify mate! cpu volts or ACC multi?

I was talking about SB voltage. DS4H has only +0.1 +0.2 and +0.3V options for it. There is Auto also but then ALL the voltages are on Auto. I have tried all the SB voltages and southbridge is sitting at about the same temp (assuming its temperature shows in AOD). I also tried to feel if its getting any warmer but I didn't notice any difference so I thought it is safe to volt it. After all, in the bios, the numbers have no yellow or red colors. Just white for SB. All the others are changing color when going up. I'm now @ 1.3V and ACC +8%.

well blah blah ... thanks for the input but i find ACC +4 and fsb set to 232 x 14 = 3.2488GHz and a higher cpu multi with a higher fsp is so far giving me the best o/c.... going to run 3Dmark 06 to see the diff... thanks man!

Phenom at 3.2 vs a 6400,6000,5000 BE CPU should be Faster overall.

Hi meizuman

Just seen you've got the same Mb as me, could you do me a favour and pm me the main points of your Bios setup to get your over clock please?

Tried a few different ways to get past 3.0 but can't find anything that will be stable and not boost my cpu temp past 60 after 10 mins stress testing
I'm a bit worried that similar clock I had running yesterday are kicking off more heat now then they were yesterday when the room was warmer bit a bit.. I'm thinking that's not a good sign - am I right?

btw fullinfusion good luck with your new board

Brad, I was able to do 3.55 GHz at 1.456v in windows, I say with 1.5v in the BIOS for CPU voltage you can basically get up to at least 3.4-3.5 GHz. you are watercooled with great temps, dont be afraid dude.


Set your NB core at 1.28v and the Hyper transport voltage at 1.28v, leave SB on auto.

Suggestion, leave your FSB at 200 and use the multi, once you find the max on the CPU start to lower the multi and up the FSB. Its easier to tell whats causing instability.


Settings that worked for me:

200x17.5 = 3.5 GHz

CPU voltage @ 1.5v in the BIOS
CPU NB voltage @ 1.5v matched with the vcore

DRAM voltage by SPD as well as timings by SPD

NB multi at x10 *default
HT link at 1.8 GHz, always under 2.0 GHz for stability on high clocks.

NB core and Hyper transport voltage at 1.28, SB on auto

leave Auto express enabled, and CPU tweak must be off!!! it gives you a crazy increase in temperatures and has no performance increase other than in super pi.

Let me know how that works.

Once you find the overclock on the CPU, then you start to raise the FSB and lower the multi, then you can also play around with finding the max speed on your NB, as well as your HT.

Note: keeping the HT under 2000 MHz and the NB at around 2000 MHz is key to being stable at high clocks!

yeah it is but i cant stat 3dmark06 and W prime.... you have any ideas why?

sweet intel dude.... illl try it in a few and post as i run it ok.... thanks mate

Thanks dude, please keep me posted, I had lots of experience with this board, i'm sure I can be of help

Apps Dont support those CPUs, i recall those apps having been updated during the Core 2 Launch so it would run properly.

I ran them perfectly fine with my CPU

well W-prim starts when you right click the mouse button and start under admin.... works now....im off to bed... going for 3.5GHz in the morning when i've had a good sleep.... later guy's

duh, how can you forget that heheh.

Ok dude, keep us posted!!

yup thats wut mine is on

 

[fullinfusion]

man i hate new lol.... its the learning all over again that gets me... and to think i had a great stable o/c on my other mobo...

yup, voltages on the SB 750 differ slightly too! Its completely different in its own way

you wouldn't happen to want to sell your 9950 if it is still working would you? I think i killed my 5kBE and would like to put my 4850e in that rig as the replacement but need to get something to replace my 4850e anyways if you would be willing to sell it give me a price and MAYBE i can... just kinda got a low budget

i will sell you mine
i will also through in a free zalman 9700 only used for 3 days before the water cooling bug hit me

already talked to CP if his is still working i will get his... but PM me with a price just in case

 

[Assassin48]

look what i got today



And the Case with some better cable management

woot woot assasin, awesome. Any benchies yet?
