Phenom 9950 overclocking

[Chicken Patty]

I have a really good feeling about this PII 940.... i think its going to spank the I7 once ya get the clock up on them.

And Cp is the intel chip that simple to o/c?
mabey ya wouldn't mind sharing whats up on the clock.... just want an idea mate.

Well, the chip runs at at FSB which on the x58 it is called Base Clock (BCLK) of 133 MHz. The multiplier is not unlocked and the default is 20x

So 133x20 equals 2.66 GHz. I was able to do up to 3.3 GHz with everything in the BIOS set on auto, voltages everything. Meaning 3.3 GHz @ 1.18v. It was as simple as upping the FSB and not worrying about anything else. Now to get to 4.2 Ghz I obvioulsy had to tweak voltages a bit like NB, SB, the memory controller (QPI), etc.

But its not like the phenom that everything has to be perfectly right or it wont clock. This thing its just easy bro hehe, i dont know how to explain it.

But, I guess thats what gives you the pride and joy of overclocking a Phenom, its not easy!!!

Thanks CP.... dam (scratches head) mabey its time for an I7

hahah, dont worry. You'll be fine.


By the way, maybe you missed my post, but I RMA'ed my board today, they said it should be back first couple of weeks of January Just in time to get a Phenom II

yeah i seen that bro... sorry i didnt post to that but i'm just playing around with the clocks.... since 3.01ghz isnt 100% stable (same settings as the M3A32-MVP mobo) on this 79-T board i decided to try the same clock but trying a different cpu multi... so i went with this... 14x 215fsb and nb ht link x11 = 2365Mhz... nb at x10 = 2150Mhz
and leaving the volts the same as using the 13.5 multi.... so far so good... i just gota find the 3ghz that this mobo likes to run, than after that i can go up from there...

thats a good starting point

I noticed the 9950 95w OC'd good. I am getting a 9750 95w, think it will OC pretty good?

 

[Assassin48]

95w i think they are 140w an 125w since the stop making the 140

They make a 125w and 95w 9750. Maybe it was 125w 9950, either way I think my question is still relevant. Think my 95w 9750 would OC better than the older 125w versions?

 

[Assassin48]

i completely missed your post (just woke up) sorry about that

Anyone here a dual boot pc with vista/mac os the new one and would you recommend it?

 

[Chicken Patty]

the 125w 9950's overclock very very well with minimal voltage. the 9750 should clock very good as far as voltage, but i dont know if they go as far though

I might be a bit too late, but ill shoot anyway...

790FX/SB600 + 140W 9950BE.... (signature rig)

I have problems going over 2.9-3.0Ghz, has anyone succeded on runing 9950 on SB600 board over 3.0Ghz? Tried voltage up to 1.45V, and the boot freezes when i come close to 3.0GHz... Tried multi 15x, runs fine, 15.5x freezes while booting, tried 220x13.5x runs fine, 220x14x freezes during boot-up... 215x14x freezes too, then 210x14x froze too, and i was like WTF?!

I tried lowering HT link speed to 1.8ghz, and still no improvement, tried lowering DDR2 speed from 1066mhz to 800mhz and that didnt help, tried upping HT voltage a notch (one step, i think it was from 1.27V to 1.32V) and nothing, tried combination of the three above, and still not getting boot over 3.0ghz... It's starting to freak me out

At 3.0ghz, im getting 37oC load @full fan speed...
I read the post (http://forums.techpowerup.com/showpost.php?p=1112050&postcount=1178) on page #48, but i tought you guys might have some tips for me before i proceed further... I'm interested since most of you have SB750 boards while mine is SB600, and frankly i'm getting worried about OC potential of Phenom II on my board...
Anyone hear if Phenom II will be able to OC good on a SB600 board?

P.S.
Everest is reporting (example) 15oC per core (23oC total CPU temp), and Core Temp is reporting 15oC. Which one should i look at, and consider it real working temperatures???

Sorry if answers to my questions are somewhere between post #20 and #1200 , but i kinda figured you guys are willing to help (as always), but if youre not up to it i might just have to read through all the 1235 posts...

Tnx a lot, Milos

Bootcamp is still the number one so I've heard man.

Hi there and thanks for sharing with us here.

First off the SB600 is very unfriendly with some of the 9950's. To start off can you give me a screenshot of CPUz of your current stable clock? Get me one of the main tab, the memory tab, and the SPD tab. Thanks once I can check that out, we go from there, sounds good?

Do you have CPU tweak on?

 

[CBOT]

CPU Tweak is ON
VDDQ 2,8V
ACC +2%
CPU NB 1,4625V

Edit :Little Update

Edit :Little Update

Please do yourself a favor and disable CPU Tweak. It drops temps by like 10ºc, thus giving you room to clock further

 

[p_o_s_pc]

does CPU tweak or ACC apply to Anthlon chips(not the ones based on the Phenoms)

I think it only applies to the Phenoms.

a quick update on my progress

well the fittings arrived yesterday and i put the computer together and was all excited and i filled up the computer with coolant and......


IT STARTED LEAKING AHHH it was 2 of angled fittings i got i dont know why but the started leaking so i removed them and tried putting them in again but they dont go in all the way just emailed koolance for a rma and i ordered some more since it will take a while with koolance to processes the rma i paid for 2-3day shipping on the new fittings so they should be here by the end of this week



Anyone want to water cool with 3/8" tubing i have a lot of fittings i am not using including angled ones if interested pm me

 

[Meizuman]

I've been thinking. Is the CPU Tweak same as AMD Boost? They both raise temps about the same amount... I have a feeling that I saw that green button with red circle in AOD back when I got 790FX board. So the AMD Boost was always on when CPU Tweak was enabled in BIOS... I am not 100% sure but I think it was that way. The red circle was there when I opened AOD and back then I didn't have any clue what it does.

Can someone who has CPU Tweak option in BIOS try this with AOD?

damn dude that sucks, nothing got wet right? Hopefully you';ll have your new ones quickly

AMD Boost enables CPU tweak thats why you notice that. AMD boost just closes a lot of things you dont need that run in the background and in the registry and stuff I guess. It improved my 3dmark score by like 500 points, not bad for free points

 

[Meizuman]

Lot of things that run in background?.... Can you verify that? Or have you been checking that it actually does more than fiddle with the cpu?

EDIT: I find that hard to believe because AMD boost can be set on - off without any loading time or change seen in task manager.

WTH is AMD boost?
