Retail Q9650 Overclocking Thread

**MrDucky** · 07-08-2010, 01:29 AM

that cpu can go much higher, mark my words :P

**Q6600** · 07-08-2010, 01:42 AM

I am worried about load temp it gets to 65degrees ! summer heat is holding me back! I can reach this OC thanks to my corsair h50 cooler! but with a vcore of 1.256volts at 3825mhz is simply impressive!!!!!!!!!

Just a heads up for all you 775 Quad o/cers out there (and dualies) - all 3 of my P45 boards are up for sale - all in great condition and fully functional:

http://www.xtremesystems.org/forums/...d.php?t=255084

I'm open to offers btw..

Q6600 - looks like you need a better board, you could probably go even further with lower volts on the USB3P, and you'd get to keep you DDR3!

Good luck with the sale bro!

hey fellas,

not been OC'ing for a few months - hungry for more!!!

any pointer??

Q9650 @ 4.95Ghz 1.275v

vFSB - 1.26v
9*455
DDR2 @ 1093 5-5-5-15 2.14v
gtl 1 - 0.675v
gtl 2 - 0.675v
pll - 1.56v
vNB - 1.26v
vSB - 1.1v
LLC - enabled
All spectrum controls - off

asus P5Q deluxe on 2301 bios

it took ages for me to get this OC stable - when i try an boot at 460 i get problems - i'm fully liquid cooled - so i'm not too bothered about high vCores -

i'm thinking - 470@1.3v vFSB : 1.28 and move my ram down to strap below as its only 1066

any tips??

**grishenko45** · 08-03-2010, 12:35 AM

update ... i'm now stable @ 4.212Ghz

vCore @ 1.325v vFSB @ 1.3v pll @ 1.56v vNB @ 1.28v thats 468*9

boosted my 3d mark 06 cpu score up from 4.095Ghz by about 450 points!!

cheers!!! hey - i see in your sig you've got a q9650 @ 4.8Ghz - what board and what PLLvoltage u got?? do you think my 1.56v PLL is too high?? thats the only voltage i'm concerned about - i'm fully liquid cooled but i dont want to fry the circuits !!

any tips - whats your PPL voltage? and what gtl refs u use?? i'm on x0.675v for both - seems to work better and give higher Gflops output that when i had them on 0.667..

**CryptiK** · 08-03-2010, 05:09 AM

With 45nm ~1.60 vPLL is the soft limit, so keep it under that, preferably under 1.57v

Pretty sure NoGuru used a UD3P for those clocks, its widely understood to be the best board for overclocking quads.

Raw CPU stability (Prime95 small FFT's, LinX) is pretty easy to do on most boards up to a point, its Prim95 large FFT's and long blend runs that really expose instability. You may find it tough to pass especially with 4GB+ ram installed. You would want to run a few hours large FFT's or blend run to be sure you're stable.

**grishenko45** · 08-03-2010, 05:53 AM

thanks cryptik - gonna say - for a 533mhz fsb on nogurus quad - its got to be a gigabyte!

i use 20 loops of linx - then game really heavily for a weekend - i recon 20 loops linx is enough games is where i've found all my instabilites with all my other cpus - when p95 was 8 hours stable games BSOD - so since then i just do
20 loops linx and hardcore game for a few days!!! good enough for me!!

**CryptiK** · 08-03-2010, 06:06 AM

Sure whatever works for you man, stability is subjective anyway. Just passing on what a few of the Q9650 boys in here (and myself) prefer to do but it's all just personal choice of course. Most guys run vPLL between 1.50v -- 1.60v but lower the better, only raise a voltage if you need to!

Yep, EP45. I don't have time to check the settings right now but I think I use 1.57 PLL and .785 cpu and .800 MCH refs.

I use prime just for the temps being lower then the rest of the tests out there.

**grishenko45** · 08-04-2010, 03:24 AM

.785 vREFs - i'm currently using .675 for my OC seems to like it and i've only got a vCORE of 1.325v

**Hoss331** · 08-04-2010, 03:55 AM

The ud3 reads refs differently from the p5q so you cant compare the numbers directly, the 0.785 on the ud3 is about the same as the .655 on the p5q and the 0.800 is about .665-.670 on the p5q.

Guys what is the best batch# of Q9650?

**CryptiK** · 08-06-2010, 12:44 AM

There are a few good ones, and there seems to be some variation between the chips within a batch. Have a look through this thread, there's lots of good examples.

systemviper has a good one for sale
but i dont think that mfII gonna cut it

**OLDcomer** · 08-06-2010, 12:57 AM

systemviper is selling x3380. Even mfII would be enough for 9.5X.

it`s easy to reach 500x9 clock with MIIF

I just need a good chip

Easy with a duel. I think it will be difficult to hit that with a quad, but it is possible.

**CryptiK** · 08-06-2010, 06:13 AM

500 FSB stable on the m2f is very unlikely tbh. 470 FSB large FFT and blend stable is all I could do. My chip is a good one too but the board wouldnt do any better. In fact my X48 REX did better.

oh no dont revive the MFII again waterflex

nightmare for quads

Agreed It's Too Bad For Quad Not Stable Over 500Mhz FSB

But UD3

Awesome Board

**Commander_HK47** · 08-07-2010, 01:26 AM

Yeah i am trying to find a UD3P to replace my maximus formula x38 that is down right now. I would like to see what i can do with my q9650 now that i know there was a board made for them.

**grishenko45** · 08-11-2010, 03:24 AM

yet another update

..... 470*9 now at 4.230Ghz - Gflops gone up too - temps ok and 20 linx stable, 8 hours p95 stable too

i recon this chip will easily do 490*9 but i'm not so sure for 24/7 usage - its 4.23Ghz @ 1.325v 24/7 - i might go to 480mhz with 1.35v - i'll see!!
