Retail Q9650 Overclocking Thread

[Jor3lBR]

Another myth down, 4500Mhz stable barrier broken

EP45-Extreme attack once again but this time I used the 5k Pot Mod to reduce Vdroop (wow what a difference on stability).

I did this last week and know I'm working on 4750Mhz stable towards my final goal -4.9Ghz-5.0Ghz-with minimal volts for normal 24/7 use.

This CPU just keeps on going with less voltage then I ever expected. I tested both 2Gb Teamgroup@1300Mhz PL8 rated stock 2.45vdimm and 4Gb G.Skills@1250Mhz PL8 rated stock 2.1vdimm.

I try to send as many SS's of the entire testing process (beginning/middle/ end) so I'm sorry if you have 56k fax/modem.

Beginning (quick Prime95 Blend on G.Skills and Team Xtreem):





Now for some real hammering/stress (25 Linx-Dual Instances passes with Prime95 in background to use 100% memory, IBT's successful runs, HCI Memtest 200%+ Pass, 3DMark, Super_Pi and Memory bandwidth)

Once again very very hard to achieve with tight timings using TURBO mem profile!


Hope you guys enjoy it

Great Work Jor mate

Yours may need a little more vcore but it should give you an idea on what you can probably use on mch and vtt.

I need 1.36 CPUZ load for 11 hs blend at 486x9 with mems on 1166 tight timmings i saw you loosen mems a lot...maybe that helps...will try later

and thanks again for the template mate

Hello there.
Im trying to OC my Q9650, but it's a little bit complicated. I hope you can help me.
First Im using those settings:
Vcore: 1.42500 (BIOS) - 1.392(cpuz idle)/ 1.376/1.344 (cpuz load)
VTT: +0.25 = 1.35
MCH: +350
Vdim: 0.25 = 2.05V
GTL REF 0/1:-3%
GTL REF 2/3:-3%

FSB: 445
Multiplier: 9
Ram: 890mhz (2.0D x 445)
timmings: 5-5-5-15

With those settings it was stable at 11hs on prime 95 then I stop it, also it was stable at 3dmark 06. But I cant luch at least 4 of 5 times super pi without errors.
The motherboard Im using is GIGABYTE GA-X48-DS4.

I hope you can help me with settings or something like that.

Cheers

Actually the timings are tighter then there supposed to be, stock timing for this ram is 5-6-6-18. It refuses to run tRCD at 5 even at lower mhz so I have to leave it at 6, other than that everything else is either stock or tighter.

[OC Nub]

In the bios when I load default settings and reboot, It reads the CPU at 333x8.5 2.83ghz. Have to manually set it to a 9 multi which tells me its reading it as a q9550. Tried the CPU on both boards and does the same thing. Flashed bios and still reads it as 333x8.5 but in bios load screen it does say q9650. Anyone else have this to happen?

Did you see any improvements on the bios you are using ?

I havent really played with the F9b yet, just loaded it to see if it would fix the S3 problem but it didnt.

[Jor3lBR]

For Prime95 it was 20oC room and 6-12oC water.

For IBt/Linx 18oC room and 3-12oC water.

[flesheatinvirus]

That is one nice chip, nice work.

[SNiiPE_DoGG]

You've got some beast ram Elano, I wish they would fix my board's compatability with D9GTS ddr3

[BababooeyHTJ]

Jor-Now that is impressive. Very impressive.

[radaja]

amazing clocks there jor3lBR!you never cease to amaze us with your skills.do you think with my temps(inside my case is about 9c) would i be ok using 1.5 to 1.6 vMCH?to do my 525fsb run i set 1.5 and still kind of worried about being too high.what do you think with my temps how high would be too high?

[Mysterfix]

I'm still working on getting my voltage down a bit but it's stable @ 4.4ghz 1.36v.

That is actual voltage measured with a DMM btw. Did anybody else notice how high the pll votage spikes under load? My multimeter is showing 1.63v-1.66v under load with pll voltage set to 1.5v in bios. Dropping it down to 1.45v keeps it under 1.55v under load.

[radaja]

mysterfix nice clock with low voltages.damn i got to get me a low vid chip.

[5010]

I don't really think that is a problem look at his load temps, vid 1,25 are cool, my vid 1,1875 can't even prime smallfft at 1,36vcore as i have 26 - 28C ambient and im on water lol, but clocks awesome

Cheers
Sergio

Same VID(1.1875) same batch L828A446 as yours.

Owned mine a couple of months running it at 4.125GHz on 1.248Vcore. The one I've got here only requires 1.15VTT up through 1900FSB (475x9)

How's yours on the VTT?

Mine is also HOT, I'm on air but all the same, I'd go faster if I could dump the heat.

Hey mate

Mine's was tested by Jor3lBR in Arizona I got 11 hours blend + IBT + OCCT on

486x9 (4374) with mems on 1166 tight timmins at 1,36vcore cpuz / 1,3vtt / 1,5pll

alsto at 4400 and 4500Mhz till 1,3932vcore cpuz / 1,34vtt

Im now testing lower volts on all to find a sweet spot on speed and temps in my country.

Cheers
Sergio

[radaja]

anyone here have an extra 9650 with low vid that they want to sell?preferably 1.21 or lower

[Zucker2k]

I have a request: this is actually OC decorum, call it what you will; please post your stability screenshots with coretemp, preferably, something showing motherboard/system temp as well so that folks know which milestones are easily duplicable based on ambients. Temps make all the difference with overclocks, and with these chips and the speeds we're seeing, these infos can save members a lot of hassle. Even if you can't show screenshots of temps, try as much as possible to indicate temps in writing; eg. ambient = 20c. Thanks.

Low vid Q9650 mania? What for, just need a fancy SS?

Good idea, i was thinking exactly same thing for a while man...

[radaja]

what do you mean by fancy SS?i want a low vid chip so i can run it at 9x500+ without having to pump it with too much vcore(1.40 to 1.45 is what my 1.25vid chip needsto run above 4400)

Thank you all for the compliments

@Radaja - 9oC blowing inside the case is great and you should be fine at 1.6vmch, I find that after 4500Mhz I need that to stabilize everything.

In my stability findings the Q9650 won't like anything beyond 65oC for long stress tests and the NB likes to stay below 50oC.

Above those temps anything can cause a Prime or IBT fail easily, despite stable settings and volts.

The Standard vs Turbo profile will play a huge role too, first stabilize everything is Standard/Auto then go the huge quest to Turbo/Manual PL8, sometimes this last one can drive you nuts on 10k, 1024k, 768k FTT's.

[radaja]

thanks for the advice jor3lbr,very much appreciated.

I am no expert at any of this by any means. Having issues with learning to oc a quad. In the past though I haven't had any better luck with low vid chips, It seems to be more the percentage of voltage increase from stock vid than the actual number (1.40-1.45 or whatever) that is needed to be stable that is important. Take a 1.15v chip and try running it at 1.4v-1.45 and watch the temps go through the roof, then take a 1.25v chip and run it at the same 1.40-1.45 and it will normally run much cooler.
