max voltage for Q6600

[skier]

what would YOU push into it? G0 VID 1.325

past 350MHz bus it stops scaling well with vcore but i'm at 380 now (3.42)

temps are fine, what are common max voltages for Q6600's (I had the Q6600 one day before I blew a board mid-December, just got my UD3R today, so i don't have any experience with the chip (first board i clocked with was a 750i that wouldn't break 2.7GHz)) at 24/7 clocks

[Ccaution]

I used to have one of those G0 @ 1.55V (MM'd) for a year or so, and it rarely idled ;) So no drama @ 1.55 given that the temps are ok... it's a 65nm chip after all ;)

[skier]

thanks, I'm Blend loading at ~60C with 1.45v at 3.33GHz without using my fan controller (so my CPU fans are running on the auto settings)

[leo27]

Wow 1.45v with 3.33Ghz!! you should be able to lower that voltage a little BTW my G0 is also a 1.325 vid chip.

[RoadconeTuning]

im at 3.6@1.58 in bio... load is 1.51 IIRC... i think i did 3.2 on 1.28v or something....

think im heading down just about the same path, set to 1.5125 for 3.465 GHz

just wish i knew more about all of those voltages

Try 3.7-3.9ghz at the same volts, 3.4 to 3.6ghz is a bad spot on the nvidia chipset. My q6600 GO did 3.9ghz with 1.43v set in bios on a 680i board.

[skier]

3.4 to 3.6ghz is a bad spot on the nvidia chipset.

what about P45 :p

[CryptiK]

P45 is fine at that FSB. I'd be more concerned for the board PWM longevity rather than the CPU's at those voltages, make sure the board is well cooled.

110895

while the cpu is loading at 70C the PWM sinks aren't even warm to the touch

[dood001]

nice....what fan is that?

[CryptiK]

Nice, looks like you have board cooling covered then :up:

[Swanie]

I am running my G0 @ 3850 at 1.45v on a EVGA 790i Ultra. Max temps are 66 degrees while gaming

[skier]

nice....what fan is that?

The white fan is an NZXT case fan from a Hades, the intake is from....god knows what, and the exhaust is the exhaust case fan from my TT Armor A90

can't seem to get much more out of it stable, but there is certainly more

VCore depend on each CPU.........................

[fordf250]

Mine ran better with nvidia also. 1.5Vcore@4G on i780 was best but never ran over 3.9G with x38,x48 or p45. It was at it best running 475x8 @3.8G and 1.4Vcore on x38 at 60C full load, was like that more than a year. Still using this chip in wifes comp at 400x9 @3.6G and stock? vcore? have not looked at it in a year. No problems 100% stable or she would be complaining.

[skier]

it's strange that all of you are having much higher clocks on nvidia, but my 750i couldn't boot 2.7

imma try dropping down to 8x to see if I can get more since I know this board should carry me to 500FSB or better

edit: stressing 434x8 3.47G

the multi is 6x at idle and 8x at load(coretemp read wrong multi)

put your ram @ 1:1 ratio & you will get more fsb for sure. You will also be able to reach higher daily oc. ;)

[skier]

well I got 451x8 stable

[Ccaution]

( I think you are very easy on that cpu termination, bump it a bit, it may save you some vcore ;) )

i would have gave it more if i had any idea what it was for :p all i got was the board and a backplate no manual or anything

and define bump

[[XC] Hicks121]

Cpu term & cpu v is too high.

You can kick up the cpu term to 1.4 & drop your pll to 1.6 & v core to 1.45. Should be able to run the 9 multi like that. Drop your multi & see how much fsb she has in her. My ud3 does 550+. X3210, x3330, q9505, e8400

[zsamz_]

pll voltage is too high cpu will degrade

[skier]

what is the highest safe CPU term? I'm on 1.44 and it still gives me voltage-related blue screens

you're all sure the highest safe pll is 1.6? 1.5v is stock

edit: also what about MCH (NB)? how high can I go on that?

also I disabled LLC now, and am starting over from 300x9

i think 1.5 is safe

but pll keep it as low as possible
i degraded a 6850 with 1.7v pll
for nb 1.4 is fine just keep it cool

[skier]

back to tweaking this again, how does everyone feel for LLC? I still have it disabled

should I turn it back on? is it safer off?

[leo27]

For a 65nm processor it is safe unlike 45nm.
The advantage of using load-line calibration is that you get a lower idle voltage and thus lower temperatures and lower power consumption when the system is in an idle state since you can set a lower vCore in the BIOS. This is because no vDroop will occur I.e. the vCore will not drop under load or in my case it actually raises under load.

The disadvantage is that it does stress the motherboard PWM's and thus cause them to produce more heat.

I have it on for my Q6600 if that helps

[Skratch]

I have my NB maxed,pll maxed and run the vcore at 1.55 for 3.9ghz on my go 6600

[skier]

just stopping at 3.5, 1.5625vcore, 1.63v PLL, 1.38v term because the mosfets on the top of the board break 60C+ under small FFT load

thanks for the help everyone!

[zenix]

I must be lucky, since i ranwith 1,55 on my Q6600 8x450 3,6GHz on my P35C-DSR3 without any mosfet cooling or heatsink. And i used watercooling on the cpu, so it also didn't recieve airflow from cpu cooler.
Bord is still working fine today :)

I think 1,6 24/7 is possible too, if you plan on upgrading, because than the degradation is nothing you need to worry about anymore.

[skier]

Just an update with a little DICE

112336

was still running too hot to get any higher though, -30C
Tube doesn't have enough mass

i could have gotten a CPUz sub for 4.1+ but I didn't have internet and the cpuz file never works for me

[karl_eller]

My Q6600 G0 has been sitting on 3.6 Ghz with 1.55v in BIOS (About 1.5v loaded) for the past 2 or so years, part of that being loaded 100% 24/7 crunching, and it's still going fine. Admittedly it's been under water the whole time and hits about +10-15c above ambient loaded.

i've got a Maximus Extreme so X38 ?

i cant get mine passed 3.4Ghz

i guess Patriot Viper Extreme DDR3-1333 aint helping cause it could be crappy ram right ?

Also CPU and Northbridge under water
