Retail Q9650 Overclocking Thread

[deachus]

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.

Hmm, I thought for sure with the vcore in CPUZ shot that you had LLC enabled. Have you tried reading vcore with a DMM? If I am ever unsure of what is reporting correctly I take a reading with my trusty DMM during LinX or P95 full load testing. Seems to me it's your MB, you should not need that much vcore for 4Ghz stability. Have you tried tweaking GTLS and Skews? I was able to lower my vcore from 1.35v to 1.33v p95 stable @ 4230Mhz just by tweaking my GTL's and CPU/NB skews.

"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.

I saw that and have read people say that it applies mainly to C1E/EIST fluctuations. Not sure but I run LLC w/o issues

[xguntherc]

wow.. 1.36 in BIOS at 1.44 in CPU-Z. I'm completely the opposite to that.

I'm currently running 4.0 Ghz with 1.35v in BIOS, and 1.320v in CPU-Z, and then 1.312v Load.

thats way off. How weird.

[Grnfinger]

how high are u talking?

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

1.44 volts is kinda harsh for 4.0GHz, I'm running 4.2GHz with 1.325vcore.
With LLC enabled, bios set is 1.325 and Everest reads vCore at 1.32

[xguntherc]

Mine is a L822B363 with a VID of 1.2500 and like I said above, 4.0 Ghz with 1.312v but thats on my 750i. so another board it could probably do better.

[529th]

Runnin mine at 1.45vcore just to see if its stable at 475fsb on my miif board

[Trigger5521]

Looks like I had some room for improvement. Didn't want to overload my tiny rad so I only ran 3 passes.

That's Bios 1.325 LLC enabled. Idle for screen shot.

[mreld3r]

It's only been priming for 30 minutes, I need a new cooler.
I can boot into memtest (usb) @4.8 ghz. Test #5 will pass twice, then the computer re-boots @multiplyer6. That means it exceeded 100C
That is with VCore @ 1.5 volts. But; the chip is still going strong. I'll wait for better cooling to try it again. Big Typhoon was good a couple of years ago; but today it just dont cut it.



My Vcore has to be 1.35 to pass IntelBurnTest @4.0ghz But; it will pass Prime95 blend much lower.

[andressergio]

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?

i always used asus and i have to turn on that option not to have such a big drop on vcore...on the MF2 works excellent, so far Gigabyte captured my heart ocing quads...i will see how it manages the drop.

Cheers
Sergio

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

I have a L845B527 got it last week I did have a quick play and it ran 4.05Ghz (450 x 9) prime small fft stable for about 30 mins at 1.26V, although I tried it on a M2F which I don't like might get a UD3P to test it out next week when I'm back home... VID of the chip I have is 1.1875...

EDIT: forgot to mention it did have a few stuck temp sensors which don't like temps below 40 degrees but at higher temps they were all within 2 degrees of each other...

[Tergon]

Go for the TRUE and lap it, you will love it, mine is running 4230GHz and runs awsome.

[Mysterfix]

I just got this one yesterday from Newegg.

Batch#: L836B361
VID: 1.2125v

I think it has a lot more left in it but my board can't go any higher. It only needs 1.26v to run stable at 4ghz but anything over 450mhz fsb and I have to poor on the voltage to VTT and Vcore for stability.

Actual voltage under load is only 1.31v for 4.1ghz.

[xguntherc]

L845 and it's VID is 1.18.. wow.. thats a great chip.

I heard that the L845's have stuck sensors in most of them, and that the newer chips didn't have sensor problems, but the recent 44's and 45's do.

A guy on ebay has Q9650's for $289.99 free shipping. but they are all L842, or L844's. and I'm trying to decide if I want to snag a second one.. but Il ike my L826 that I have.

Can you guys post what batch #'s you have, what the VID's are and your clocks? I'm trying to decide what to do. maybe we need to start a official Batch # / VID thread for the Q9650's.

[Martin.v.r]

?
have sold my Q9650 and barter over with a QX9770 a good one, but when I throw Q9650 into his motherboard, it can run 4GHZ prim at only 1.1285v whit a ASUS Rampage Extreme
so now I have even ordered a ASUS Rampage Extreme, instead of my ASUS P5Q Deluxe.
Think that there is so much different on a motherboard.

I am not unhappy with my trading,Butt ??
I had had such a motherboard from strart, it was probably not have been sold, thinking of how far I could be reached with this motherboard

I dunno about your trade mate and how Asus run on these Quads but I guess they all do better on UD3P's and Ep45-Extreme.


Those are a hell of a lot volts for that FSB for only cpu-z runs (no stress IBT or Prime95).
Probably a bad chip or bad mobo or both so I couldn't say much you should talk to Sergio and Radaja, both traded Asus for Gigabyte and they are very pleased.

[humeyboy]

Bios 1902 ?

Link plz

I've been reading this thread over the last few days after picking up a new Q9650. L843B805. I'm running it on a EVGA 780i A1 which comes to my surprise it isn't one of the better boards. Well it's what I have to work with so I will throw out a few things to see if I can get a few tips.

I've done my best over on their forums but they seem to be a bit less active than this thread. And you guys seem to have a handle on this better than most.

Right now my rig is running at 4000.5 445X9 and my Vcore is set to 1.40 bios which reads 1.376 in CPU-Z.

I've been hesitant to go above that vcore setting without really understanding the temps and what I should be looking for. So far this thread has vcore settings anywhere from 1.27 all the way up to 1.5 and so on.

She boots fine and I have yet to have it crash on anything other that Prime95 with the Small FTT test.

Under idle it runs low 30C and under Blend it will run mid 40-50Cs Under Small it will go up to around 60C.

I'm also running an older Zalman 9700 LED which I've read isn't cutting it at these speeds anymore.

So question is it worth getting it Small FTT stable and if so am I okay to keep going up in vcore? What Temps should I watch out for...

Any advice would be appreciated.

Under 65c load would be fine imo, some say 70c is ok.
Your temps are decent for air cooling and if your happy with your rig at 4.0GHz then why bother to play with it. If your able to use it 24/7 and have zero issues then I would say do not fix whats not broken, if your looking to squeeze a few drops more out of the chip then post your bios setup and we can make some suggestions and help get you where you want to be.

[mreld3r]

Could this mean that my IHS is not flat? Would lapping help me any here?

[The Water Dog]

Yeah, lapping could help you=)
I get hooked on lapping when i see what the result was on my first one.

[TheGanG]

Could this mean that my IHS is not flat? Would lapping help me any here?

What cooling do u have? If water, have u a back plate? Too tight? Lapping may not help in all situations...

Edit: Well, i see u have a Big Typhoon

[unclewebb]

The thermal sensors in the 45nm Core 2 Dual and Quad processors are very poor at reporting accurate core temperatures. You can lap your CPU until it's as smooth as a baby's bottom and as shiny as a mirror but you'll probably still see the same pattern when it comes to your reported temperatures. Reported differences of 10C between two cores sitting side by side is not uncommon at all but that doesn't mean that the core temperature is actually different by 10C. In the majority of cases, it's mostly just sensor error.

You can also try RealTemp. It gives you a few more options to see how your sensors respond at different loads by doing a CPU Cool Down Test.

Man I'm seriously thinking about getting a UD3P, this X38-T2R hates going over 450 with a Quad. I can get it to 456 with a little arm twisting but now my ram keeps freezing the PC during videos. I know it's not the CPU because it passes Intel burn test and 12hrs. of Prime95. I know this Quad has more left in the tank, I'm at 4.1ghz with 1.3v vcore, 1.34v VTT. I can't go higher no matter what voltage I pump through the board, it just locks up just before or shortly after booting into Windows.

Welcome to DFI + Quads combination my friend. It is not a good board to use with these chips. I had same processor in my DFI X48 (check my build log in the sig) and maxed out with CRAZY voltages at 472 x 9 (1.6vtt 1.8pll etc)!

Now I'm happy at 4680Mhz (520x9 IBT/Prime stable) with 1.30vtt/1.5pll/1.389vcore.

Well I finally had my first crash under normal gaming... So I'm looking really for stability at this point. I think I have very conservative numbers so far but I just don't know the bounderies.

Here are my current settings

Q9650@ 4000.5 Ghz 445X9
vcore in Bios is set to 1.4 CPU-Z is 1.38
CPU FSB 1.3
Mem 1.9 (Stock)
SPP 1.45
MCP 1.55
HT- SPP-MCP 1.25

All Spread Spectrum Disabled

Temps are low 30C at idle and under normal game load low 50C. Under Small FTT they reach low 60C. CPU Cooler Zalman 9700 LED


Goal is stability and of course I would like to go higher if possible...
