Retail Q9650 Overclocking Thread

[BababooeyHTJ]

Folks, don't bother with any core temp readings below 50°C - they are simply not accurate. Quote from this recently released Intel datasheet regarding the thermal sensor issue:



From my own tests, I found it better be corrected to "60°C" to be closer to reality. Anything below 60°C in my experience doesn't make much sense at all.

Also here's an article at Tom's HW that's worth reading. It talks about how to set the Tj Max value accurately for your CPU.

Im pretty sure posting a link to toms is against the forum rules or at least it should be.

My chip has 3 stuck sensors, my old wolfdale had one as well. Once it gets above that temp it is accurate.

[Grnfinger]

I have found that to be true.
After testing yesterday, the temps seem to even out above 50c or so, core1 is still 10c higher on load but it now dosent bother me so much.
Thanks for the info

Late to the game here
Just pick'd up a Q9650 FPO L828A446

4.2GHz was a walk in the park, but my concern is the temps.
3 cores are nice and cool 29c-31c but the 1 core is a staggering 40c, this is water cooled and yes I have checked the mount and reseated twice.
Anyone else have this issue or am I the lucky winner today?
I'm in no hurry to lap the the chip for I might sell it if I cant do 500x9

Hey Grn i have the same batch , my mate Jor3lBR get it for me and also the UD3P great combo !!! still on my way to my country, such a low vid it's hotter than my other 1,25vid, but in the end he told me that the domino was not doing good contact so will see how it goes on my D-TEK block, also some sensors where stuck at first start all stock but after some burn in days they start moving

Here are some tests he did...

The Chip


Firsts stabilty tests on XP64 SP2


IBT and OCCT tests on XP64 SP2


Some 10h Blend tests with some more VCore on Windows7


And the most awaited one needs more work but a very nice start

I wanna thank all members of this thread and others for all the great help always and specially to my friend Jor3lBR for his hard work and patience, thanks
for your pics, screens and all the time you spent on finding a good one and testing it day after day
You rock mate

Thank you mate I'm anxious waiting the combo

Yes you have a sweet chip there for sure, and you have motivated me , I just managed to reduce vcore for 4200, still tweaking but its looking good

Hey Sergio,

I'm glad you're happy I enjoyed buying your system and sending it to Uruguay keeping my promise of making the Q9650@4500Mhz run Prime95.

I told you there is no better combo then the UD3P+Q9650

Your system was great to tweak, took me those 3 days as you know we talked most of them during the OC's in MSN.

Hopefully it will arrive safe next week so you feel the power of 4500MhzQuad!

[andressergio]

That was my intention , so far i sold the MF2 it was holding me back like crazy this UD3P are awesome mobos

Cheers mate tell me what's your vid ?

Thanks my friend of course i'm happy if have no more fingers to cross my hands and feet are crossed to pass customs this next days

And i forgot to mention that all of this work you done on just 3 days and some couple of hours each...

Cheers

Core Temp reports VID as 1.15 so does Real Temp.

I'm tempted to try out a UD3P, 500FSB is bootable just not 3d stable yet.
Messing with clock skew now to settle this chip down.

Yes this UD3P's are much better for sure...you'll get some rock solid clocks there...

Cheers and good luck

Batch# L844B801 SLB8W Pack date 01/29/2009
VID 1.25 (no stuck sensors)

4.05mhz Linked and synced with 8GB's of DDR3. This was very difficult to achieve with my S2E, she's a real beeatch with 8GB's of RAM. Have posted and booted in Vista as high as 4.14mhz linked and synced but not prime95 blend stable. Working on lowest possible cpu volts with LLC disabled now. looks like she needs at least 1.42 underload to hold 4.05mhz.

Nice vid mattlyall06 its a good balance between heat and OC congrats

Why LLC disabled mate ?

[Trigger5521]

Why LLC disabled mate ?

On the S2E's it over volts to hell, it has also been linked to instability with BSOD's at idle and what not. I have not had any issues but I wanted to have stable settings both ways.

LLC enabled cpu v1.33 in BIOS
LLC disabled cpu v1.63 in BIOS

I think I have a crazy board.

Nice work there man... GReat chip and nice of Jor3 to help you out and mail it there.

I'm now wanting a better board after seing you people's results. but I've yet to try and OC my chip with my new Water loop. I'll be doing that tonight, or tomorrow.

Thanks xguntherc yes very nice gesture from my friend Jor

And yes this UD3P's are awesome boards.

There's some new batches for the Q9650: L845B527...
I can't find informations on it.
Hope that these new Q9650 will have some better OC than the last Q6600s...
L844xxxx seems to be nice BTW

L825B425

Clocks very good but needs high(est) voltage (around here)

[mattlyall06]

Why LLC disabled mate ?

out of curiosity, if you dont mind me asking, what is your opinion when it comes to load line calibration? why have it enabled rather than disabled? i have it enabled and dont seem to have any problems. why are alot of people so reluctant to enable it?

[Trigger5521]

how high are u talking?

Look at mine L844B801, 1.36 BIOS = 1.44 1.42 idle everest and cpu-z.

[deachus]

Wow, that's pretty high voltage for 4Ghz. Do you have LLC enabled on that shot? The reason I ask is because I am running 480FSB, 4230Mhz p95 stable with 1.33v set in bios and CPUZ reads very close to that with LLC set to Auto. I have yet to gain anything with LLC enabled on both my P5E3 Premium or P5Q3 Deluxe. Most of the time when I enable it my system won't post. Better stability with it set to Auto, that's just my experience.

Here's the specs on my Q9650:

SLB8W
L844B781
VID: 1.235v

On the Asus Striker II Extreme Anand article has this to say about LLC. LLC has caused some 790i people to BSOD/reboot at idle.

"Loadline Calibration - [Enabled, Disabled] Setting Enabled will effectively remove any negative feedback in the CPU supply voltage regulation circuit. This means that there will be little to no difference between the CPU supply voltage at idle and full-load. This does not mean however that there will be no offset seen between the idle voltage and the CPU Voltage VID as selected in BIOS. Disabled follows the Intel specification and allows the CPU supply voltage to droop under load as properly designed. We recommend you leave this Disabled and increase CPU Voltage as needed to satisfy the minimum operating voltage needed under load.

LLC is disabled in that shot. BIOS is set to 1.36. My board either overvolts like mad or the board is misreporting the voltage. I'm sorta leaning towards misreporting because when I look at the voltage monitor in the bios itself, it takes 3 or 4 setting changes to get it to move. What I do know is if I lower my vcore one notch I'll BSOD Intel Burn test and error our Prime95 blend.
