*Official Retail G0 Q6600 Overclocking Thread*

Very nice B3 you have there! Can we see some prime95 love?

Rbs.

You need whatever vcore and other tweaks it takes too get your CPU stable at 3.6(if it can do 3.6) Just cos other are achieving 3.6 it on lower than 1.4v doesnt mean your CPU will do it. I need 1.425v with PLL 1.6,FSB=1.4,NB-1.4 on a P5K premium. for prime stable and thats with good ballistix 8500 memory . I would start with upping the vcore and loosening the memory to 5,5,5,15 - if you get it stable then try tightening the memory. Better cooling than a Zalamsn 9500 would also be a good idea -e.g. 120 extreme or ultima-90(nice small profile) will give better performance.Try MX-2 paste - doesnt need to cure and good as AS5.

Thanks for all the replies.

I'll get a new CPU cooler and some MX-2 paste before I start tweaking.
I was going to buy a ZALMAN VF1000 cooler for the 8800GT but with the REV 2 BIOS upgrade it seems to be fine.

whats VID i keep seeing guys talk about this?

[BLHealthy4life]

whats VID i keep seeing guys talk about this?

I believe VID is the default voltage that the BIOS reads the CPU uses without any Vcore adjustments.

I could be wrong....

Yes, my understanding is that VID is the standard Vcore for a particular chip as well.

Move over G0, there is a new B3 in town!

Here is my overclocks on the B3.

just wondering what temps you are hitting on full load? and on what cooling solution? air, water or something else?

[JonnyG]

From my experience VID has been important. I've had 4 chips and typically had 4 chips with High VIDS. 2 x 1.325v 1 x 1.3125v and 1 x 1.2875v. In terms of overclocking the lower the VID the better the overclock has been hence why i have kept the 1.2875v chip. I run it 24/7 at 3.6Ghz with 1.4 (about 1.392 loaded) for games but its not prime stable. To get that i need about 1.42v loaded i would imagine. But managed to do superpi 1m at 4.158Ghz with 1.544v on air (as long as its cold enough) so it aint too bad. I would love one of these real low VID chips but after 4 attempts i've given up trying, lucks never been my fortia (however its spelt).

Was wondering if anyone has any suggestions for getting my Q6600 G0 to 3Ghz - can't get it stable above 2.8Ghz atm. Have tried 9 x 333 and 8 x 375 to get past the FSB hole these 650i SLI boards seem to have but no dice.

Voltage Control
DDR2 = +0.40v (2.2v)
NB / HT Link = +0.1
FSB = ?
Southbridge = +0.1
VCC12_DL = +0.1
CPU voltage control = 1.375v

FSB - Memory Clock mode
Linked

FSB Memory ratio (Sync)

CPU host frequency (333Mhz)
Actual memory clock (667Mhz)

If anyone has some other tips, I would greatly appreciate it. I've been tearing my hair out over this - been getting a lot of hard power-off shutdowns too - after inputting settings into the BIOS, the rig will just switch off completely.

[kup]

Hehe, hey Jon!

[megahurtz-oc]

check this out all on air 3d mark stable all voltages set to auto. was playing ut3 and crysis with same settings all nite never hiccupped. just put new rig together last week. very happy.

Well I am not familiar with Gigabyte Boards, but you have a nice processor there, as some else with that Batch# say it has a VID of 1.2000v, so you should get to 3.0GHz with no problems.

It appears you have more than enough Voltage there at 1.375v (you can drop to 1.25v, even stock voltage of 1.20v is possible to reach 3.0GHz), what about increasing the NB Voltage (mine is at 1.60 and I have reach 3.8GHz P95 stable), did you check memory voltage (mine is at 2.1v for 3.6GHz see signature).

FSB should be 334 (to reach 3.0GHz) which means at 1/1 your Memory should be capable of running at 668MHz. (ie Min requirement DDR2 667/PC2 5300). So can your board do FSB 333 (I would think most Boards would be able to do that).

If you think you are constrained by your board, what upgrading the Bios to a different version? Maybe Gigabyte has a fix, if it is a board problem.

What is your Power Supply like?

Deffo your motherboard, the 650 don't clock quads very well.

Get a P35 motherboard like the P5K-E and you will hit 3.6Ghz with ease.

PSU is an Antec True Power II 550W - I have thought that was an issue - especially seeing as it likes to just shut itself off suddenly while ocing, which I've never encountered before - crashes, BSODs, error msgs - yes. A hard switch-off? Never.

I'll give your suggestions a go and see what happens - only thing is I'm not sure what the default voltages for the NB / SB / VCC / FSB are - as the Gigabyte BIOS only shows +0.05v changes from the default (without actually telling you what that is)

BIOS is latest F2 version but I have a feeling the 650i boards don't oc quad-cores that well (as Devious) has mentioned. Reading up Shamino's review of the same board a while back, he was only able to hit 330Mhz stable with a quad-core before he had to volt mod the board. Dang. Shoulda done my homework better.

Devious> only problem with getting a P35 board is I've got 8800GT SLI and running it on a 1080p 47", I'll be needing that SLI...

[[XC] 4X4N]

Have had this chip for a little while, actually got it from another member here. I wasn't able to get even 3.6 stable whith my DS3-R, massive vdrop/vdroop. My wife got me an early present, a P5K premium. Loving this board.

734B 10/11/2007 Pack Date

9x413 prime stable 1.5125 in bios


Used setfsb for highest 1m at the same voltage. Times are nothing special. Just have some value ram at 5-5-5-18.


Going for 4ghz, damn almost. One bump up in voltage would surely do it, but I didn't try.


3.6 @ 1.425 in bios will be my 24/7 WCG chrunching setting. Temps stay right around 50c with a Thermalright Ultra 120 Extreme and 2 yate loon medium fans in push pull.

Just as a guide my defaults on my board are NB 1.25v, SB 1.50v and FSB=266, but this may not be applicable to you as manufacturers have different designs and components for boards they make.

I think you should do the volt mod as that may be your problem with this board, appears 330 FSB is your limit without the mod.

Whatever you do keep your processor for your next upgrade, it is a good one, but you can check CoreTemp to confirm that the VID is indeed 1.200v

[PCTools]

At full load temps will increase to low 60's. 1.625V on Vcore for Orthos stable. For just running Windows and playing FEAR, (Not benchmarking), I keep it at 1.4875V.

As for the water setup, it is an open loop. Water from the sink goes into the loop and then exits to the tub. So, the water temp is at 50 - 55 degrees!

Man, people are getting some nice overclocks with this Q6600!

just wondering what temps you are hitting on full load? and on what cooling solution? air, water or something else?

[jammin]

new watercooling in the case and the quad gives fire

[PCTools]

Congrats, Very Nice Scores for Air.

check this out all on air 3d mark stable all voltages set to auto. was playing ut3 and crysis with same settings all nite never hiccupped. just put new rig together last week. very happy.

[tatts]

I really need a new mobo i think. This DS4 & Q6600 does 3.6GHZ with 1.35V (10hours of P95 stable) but it just wont do 3.8GHZ, even had the Vcore upto 1.6V, mch & fsb to 0.2 and it still reboots.
Mobo may be faulty though has i got a noise like a cricket coming from the cpu which gets louder the higher the clock/Vcore goes

So, whats the best O/C board for these quads? money doesnt matter aslong as i can run my DDR2 in it

[megahurtz-oc]

i had booted it at 460 X 9 last nite with 1.50vcore but didnt run any test. that told me i could play at 425 X9 ill test more later.

What were your FSB / NB / SB / VCC voltage settings? I'm guessing you have a similar BIOS to my DS4L

[4Qman]

anyone know if a L733B433 SCLAR Q6600 is any good?

thanks

[Hyde`fK]

Would like to ask what other 680i SLI board is available with the GTL ref voltage fixed besides Asus Striker Extreme new revision and eVGA 680i SLI A1 Rev. for quad core overclocking? Thanks.

[varblane]

I can get 3ghz on def voltage. But when i go for 3.2ghz and do around 1.4V i cannot get it stable. When i do the auto volt, then it sets to 1.37(5) and its stable. The mobo is GigaByte p35-ds3r. Do i need to add some other voltages other than CPU?

[Akane]

What FPO/Batch number is your chip? Mine's week 37 B batch and it's pretty crap, now @ 3.4Ghz @ 1.45v, not Orthos stable tho.
