***The Official Q6600 Overclocking Thread ***

Is system memory multiplier settings the one which change your final RAM frekvency? You should be able run it at 1066 at 2.10V no problem.
 
Core 4 fails on mine almost immediately at 3.6ghz in prime 95 64 bit. Will have to try and stabilise later today.

Update: It appears that the droop is quite significant on this board. At idle 1.37v, and load 1.30-1.32v. so averaging 0.06v droop. I take it this is reasonably bad?

I also dropped the northbridge volts very slightly to improve temps, to seemingly no adverse affect at present (beyond the already failing prime 95).

But.. the test lasted longer, but not by much. Definately not stable at 1.3v on this board. Perhaps it's due to me using 4 ram modules?

UPDATE: Couldn't quickly get 3.6 stable so going to work up to it. Stable so far at 3.4Ghz on prime 95 and small's. Only been about 7 minutes though. Temps at 72/72/68/68 according to to CoreTemp, but 55C according to Asus PC Probe.

Did you set 400 x 9 or 450 x 8 cz i couldnt get 3.6 stable with 400x9 so try lover
multiplier. My settings for 3.6Ghz stable:
450x8
1.39 Vcore
GTL auto
CPU PPL - 1.52
FSB Termination - 1.32
Ram - 2.10
NB - 1.24
NB GTL - auto
SB - 1.10
PCIE SATA - 1.50

Btw temps are high over 70C :(
 
Thanks for the settings advice, Will try later :-)

Previous owner had it at 400 * 9 @ 1.3v so I didn't see the problem :-( Bit dissappointed, but that's the difference in motherboards I guess. Temps shouldn't be 70C + then, D'oh. Will have to try and reseat the cooler. Pain in the arse, whole motherboard out job lol.

EDIT: BTW.. temps were from 'Coretemp'. Whilst Asus PC Probe was only reading 55/56 Celcius. Not sure which to take tbh. Have also just switched to 5:6 ratio for the memory rather than 1:1. Takes me to 906Mhz on 800Mhz ram, but I was running roughly the same before so it should be OK :-)

i have also noticed different temps between coretemp, realtemp, hwmonitor and occt.
iirc its to do with the tjmax.
some set it at 100, but as far as i know it should be at 90
 
Can I overclock my q6600 on an Abit FP-IN9 fatality 650i?

Tried clocking from 2.4ghz to 2.8ghz on default voltage but computer does not even load bios.Have to reset with jumper back to defaults.

Any suggestions?
 
The poor quad overclocking was not so much down to the 650i chipset but more down to the weak cpu power design that was paired up with most of these entry level boards.

The Asus P5N-E, Abit IN9 and EVGA Ultra were the most popular 650i boards at the time.

The EVGA Ultra was the only 650i board with a 6-phase power design and as such could clock a Q6600 G0 a good 400mhz higher than the asus or abit board. Ive seen people hit 3.6Mhz with the evga, where as the asus, abit and msi boards crap out at 3ghz~ ish

Rycon11, your IN9 has a 4-phase power design, so vdroop is still going to be a big issue!
going from stock speed to 2.8ghz can see a power increase of as much as 20watts for all 4 cores on the cpu so your stock voltage will droop significantly and causing your instability. you simply need more vcore to get the system stable.

Its inevitable you'll end up fighting a loosing battle with that board due to its poor cpu power design, as technically its still not going to have the guts to overclock a q6600 in excess of 3ghz.

Here are my results for 51 passes of Intel Burn Test.

[email protected] (VID 1.2625v )
Gigabyte GA-EP45-UD3LR
4GB (2x2GB) DDR2 Kingston HyperX PC2 8500 1066MHz (running@1008MHz) dual channel config

Cooling solution: IFX-14 with 2x Akasa Viper fans and MX-4 thermal paste

Bios Vcore: 1.4250V
Idle Voltage: 1.376V
Load Voltage: 1.312-1.296V

Chose 'Free' ram available from Windows task manager. Actually sligtly less value of 2400MB for more accurate testing hence higher value of over 40GFlops.

There is always a difference of 7-8C between core0,1 and core2,3 no matter what thermal paste I apply. I use the horizonal line method as recommended for core 2 quads.

The temps never go above 70C although the core temps do depend heavily on the ambient temperature aswell. If the room is very hot, then intake fans will only be drawing in hot air and viceversa.

Also my mobo has only 4 phase voltage regulator hence the large collective vdrop/vdroop of 1.4250v-1.296v = 0.129v which is massive. If I was using a 8 phase board, I am sure I wouldn't need as much voltage in the bios and my vdrop/vdroop would have been lower aswell.
Thats why I believe Asus P5Q Deluxe is the best and most efficient board for overclocking Q6600 and afaik it has 8 or 16 phase voltage regulator and people with VIDs of higher than 1.3v have reported to run [email protected] stable.

However all Q6600 chips are different and one Q6600 result isn't reflective of all the Q6600s out there. Overclockign & stability testing also depends on Mobo chipset, the northbridge (MCH) cooling design and also the ram settings:).

But I would like to ask if my voltages are sustainable for long term usage of [email protected]?

So in a few words I should not bother with overclocking my cpu since I would have problems to even get it to run stable at 2.8ghz?
 
What settings would i need to input on my bios to be able to run a G0 at 3.2 ghz. new to overclocking, but i have read a lot about it i would just like a vague idea on what it input to learn from!

my cooling is a CM V8 and my mobo is a asus p5n-d

Thanks!

Sell the 650i motherboard and get a reasonably cheap 2nd hand P45 board :-) That will massively help you overclocking potential :-)

thanks, but possibly somethingthat doesnt involve me spending more money? i cant really afford to get a new board and i have no one to sell this board to.

the next time upgrade it will be to a sandy bridge so i just need to OC a bit on this board for the time being.

This.

I went from stock straight up to 3.2 just by changing the FSB and ram divider :cool:. Currently getting 17 deg idle and not more then 38ish under load (went up to 50ish under prime, but I've never seen it hit that in normal use).

edit - Sorry, didn't see your post saying you didn't want to spend anymore.
