help overclock q6600

Hayder_Master · Feb 4, 2009

hello guys i am very mad cuz i can't overclock my q6600 /G0 like many guys here , only i reach 3.2/8x/1600 so i need more like 4.0ghz how dumm before i kill my cpu with high voltage , im sure the only problem is i am not deal well with my p45 there is too many new options this is my bios just tell me what i set to get extreme overclock
forget the cooler right now o just want too see some overclock deserve good cooler

Now I reach 3.45 /8x/432/1728 but the voltage still on auto mode I can't set it even 1.45v , and the cpu voltage show in cpu-z 1.488v , I know the problem is the vdrop but here is my bios and I need help guys
just tell me what should i try or change in my bios to get high stable overclock
Thanx alot

Have you got a 2008 quad? If so you might have topped out. Only 2007 q6600 can usually hit 4ghz. Why do you "need" 4ghz? I'm sitting quite happy at 3.2Ghz at stock voltage!

r9 · Feb 4, 2009

Use x9 multi so you want be FSB limited. Lower mem ratio and raise timings when you achive desired OC start tuning mem timings and ratios. Set CPU voltage manually in bios there is not optimal voltage just watch not to go past 65C when testing with Orthos. Raise the SB and NB votage to 1.35 -1.4.

DISABLE AUTO PLL / VTT ON GIGABYTE BOARDS. From that bios layout, I assume you're running some type of gigabyte p45 variant. Auto sets the PLL to 1.85 and VTT to 1.7 or something insane like that. Put your PLL to 1.5 and VTT to 1.24-1.3

Also vdrop is not a problem if you have LLC enabled (which it looks like you do), but I personally wouldn't recommend it even though many say it is safe on 65nm chips.

Bump your MCH core to 1.3, vtt to 1.28 and vcore to 1.5 LLC disabled and see how far you can get on that

i know my mobo can move with high fsb that's why i go and take it and i see some guys hit 500fsb with same mobo, and why raise SB :confused:

now im get stable state on 3.45/8x/432 on this
cpu vcore 1.5 (cpu-z shows 1.472)
cpu pll 1.610
cpu terminiation 1.3
Mch core 1.4
looks normal overclock for me cuz i want get a watr cool system so i want my cpu deserve it
thanx guys for help i need update please

Homeless · Feb 5, 2009

I still recommend a 1.5 pll setting. 1.57 at most

Hayder_Master · Feb 8, 2009

this is what i get and set
3.45Ghz /8x/432/1728
cpu vcore 1.5000 , 1.472 show in cpu-z
cpu termination : 1.400
cpu pll : 1.610
so like i see it is too much voltage and normal overclock , so what about more 3.6 and over

JC316 · Feb 8, 2009

What stepping is the chip? B3, or G0? I needed 1.6V under water to reach 3.8GHZ with my Q6600. I think that I needed 1.5V to get 3.6GHZ.

raise the multi and lower the FSB.

400x9 is going to give you 3.6Ghz and need less voltages than 4xx * 8

I only need 1.40v (shown in CPU-Z) for 3.6GHz on all my chips. Just make sure you raise the FSB strap (if your board has one) to 400, and increase NB voltage if needed.

Dont forget that sometimes higher NB/mobo voltages can lower your need for higher CPU volts.

G0 , 1.6 wow that's too much can we say this is max voltage and how long cpu life time with 1.6V cuz im think with watr cool , thanx and i will replay

ok i am try this but fail in boot with auto set , so im go try it with 1.4(1.45 in bios maybe) voltage , thanx and i will replay

Mussels · Feb 8, 2009

i use 1.425/1.4375v in bios to achieve the 1.40v real.

Wile E · Feb 8, 2009

Both of my G0 Q6600's needed 1.5V for 3.6GHz. I was able to leave cpu termination and cpu pll voltage on auto, and I set the chip to 400*9.

Was that 1.5v real, 1.5v CPU-Z or 1.5v bios set?

1.5V real

ok i am gonna try it and reply for results , and what about 4Ghz , thanx a lot

ok i will try it , but about auto set to pll and termination i don't know how much rise up , sometimes my mobo give high voltage like i set auto with Vcore at 3.45 the Vcore show 1.488 in cpu-z when auto set now i set it at 1.5 but 1.472 on cpu-z so what about pll and termination maybe rise up high and maybe crash my cpu , thanx

agreed how much Vcore show in cpu-z

Fitseries3 · Feb 8, 2009

use the 9x multi.

.63x cpugtl
.67x nbgtl

1.5v may be needed for 3.8 and up.

Hayder_Master · Feb 9, 2009

try 3.6 with 9x boot ok but fail boot windows , and with hell voltage
cpu vcore 1.550
NB try 1.4 and1.55
SB 1.3 and 1.4
cpu pll 1.610 and try auto
cpu terminiation 1.4 try auto too
dummm, any solution for this overclock it can't be no way
and i see my cpu version in real temp is 1.3250 so my friend q6600 version is 1.280 , what is the different some guys say old one reach high overclock and other say the new one reach high over clock but with need high voltage more than old one , any idea

Mussels · Feb 9, 2009

you most likely need to adjust other settings. Northbridge voltages, GTL settings, FSB strap, memory clocks.

before throwing more voltage at it, try easy. get the system working at say, 400x7 and work your way up one multiplier at a time.

Hayder_Master · Feb 10, 2009

hit 3.6 but with extra voltage
this is 3.6/400x9 and 3.6 /445x8
vcore set 1.58125 and NB also 1.6 and SB 1.4

after that i am try 3.8Ghz with 1.6V dos boot ok but blue screen windows boot
also try 4.0Ghz with 1.6V too but no boot at all
and i want ask too about cpu life time with high voltage , like how much expect cpu lifetime when cpu Vcore 1.5 real

i cant even make mine stable due to the heat at 1.45v real, if your chip was the same as mine (early G0) i'd say those voltages are a bad, bad idea.

That said, i've heard that the latest G0's need more voltage to OC - and that they dont die as easily.

Hayder_Master · Feb 10, 2009

yes my friend it is G0 , and that what i was hear too about new g0 about more voltage but i don't know about don't die as easily that's good news so can we say 1.7V is a dead voltage for my q6600 , my new q6600 make me very confused with 1.3250 VID , and what is your cpu VID

Hayder_Master · Feb 23, 2009

now the good news is my board have 0 vdrop , there is no drop voltage at all , just only some decrease in voltage show in cpu-z less than bios set , but under full load the voltage still stable and without any drop , so now my only problem is cpu and last try im go with 1.6400 in bios which is mean 1.600 or 1.610 in cpu and failed to hit 3.8
dumm just who can i hit 4GHZ i know is not impossible many guys do it and i want to do it too

the 4GHz people are always on water cooling, or better.

Tatty_Two · Feb 23, 2009

I dont know if you have answered this question already and I just missed it.....whats the chips ViD? look in realtemps/coretemps it will tell you.

Apart from the obvious that has already been stated, that recent Q6600's dont overclock well (your Vid will also indicate this I guess), for a P45 your Northbridge volts are too high, in my own experience with the P45 chipset along with many other forums, you should avoid going above 1.4v without active NB cooling if possible, it may simply be NB heat issues causing the instability (notwithstanding crap Vid/stepping), I can hit FSB's exceeding 500mhz with a quad on just 1.4v NB.

Fit's recommendation for GTL references are good (they work well for me) but not sure if those will work for a 65nm chip, if not, keep them on "auto"...... just for the purpose of testing, put your NB strap on auto and all your DRam timings on auto, you can change them back later ...... give that a try, in my experience (although I cant speak specifically for Gigabyte) the P45 loves auto settings.

now i get an gigabyte G-power2 pro cooler and performance look good , i just want see my cpu hit 4G and after that im goona think about best cooling

you right man i post it before my VID is too high 1.3250 , so i want to know is this cpu can't hit 4G or need crazy voltage to do it , ok im go set everything on auto except cpu Vcore , please help me before i kill my cpu im already have suddenly lost all my HDD's
