Hi,

i know there are a few threads on this CPU and MOBO but i can't seem to get the same results.

at the moment ive got my Q6600 at 3ghz and i was to push it to 3.4-3.6

ive tried following some of the instuctions in other threads but my PC doesnt boot and i have to hard shutdown the PC.

(MY SETTINGS ATM)

External Clock - 334
Multiplier - 9x
DRAM Speed - 1:1:20 (DDR2-1333)
PCI-E - 100

CPU - auto
DDR2 - auto
CPU VTT - auto
MCH - auto
ICH - auto
ICHIO - auto
DDR2 REF - 0%
CPU GTL 0+2 - 67%
CPU GTL 1+3 - 67%

Limit CPUID MaxVal - Disabled
C1E - Auto
Execute Disable Bit - disabled
Virtualisation - enabled
EIST - disabled

RAM - manual 5-5-5-15 2t

Q6600 @ 3Ghz G0 stepping revision VID 1.1375
35ip Pro
4GB (2x2gb)ram XMS2 8500c5


i tried to input this:

External Clock - 400
Multiplier - 9x
DRAM Speed - 1:1:25 (DDR2-1000)
PCI-E - 100

CPU - 1.52v (1.42 or so under load)
DDR2 - 2.0v
CPU VTT - 1.23v
MCH - 1.29v
ICH - 1.05v
ICHIO - 1.5v
DDR2 REF - 0%
CPU GTL 0+2 - 67%
CPU GTL 1+3 - 67%

Limit CPUID MaxVal - Disabled
C1E - Auto
Execute Disable Bit - Enabled
Virtualisation - Disabled
EIST - Auto

RAM - By SPD

any help would be fanstastic.
 
Most DDR2 i've used prefers slightly higher vdimm than your current setting,i'm currently using 2x2gb of kingston 1066mhz which requires vdimm of 2.2v.
 
thx for the help Vader, i put the ram and Vcore to what you said

im at 378*9 =3.4Ghz

temps have maxed at 75C while using prime95 for 50 minutes is that a little high?
 
yeah vdimm = ddr2 voltage

75 degrees is fine.

I usually turn off c1e and eist when overclocking on my ip35 pro.

To get the most out of a quad chip you will have to play around with the gtl %ages which can be quite time consuming.
 
try 1.40v cpu vcore
9x 390

1.45 shouldn't be needed for 3.4-3.5ghz

put the north bridge voltage up 2 notches from auto

CPU - auto > 1.40
DDR2 - auto
CPU VTT - auto
MCH - auto > up two notches
ICH - auto
ICHIO - auto
DDR2 REF - 0%
CPU GTL 0+2 - 67%
CPU GTL 1+3 - 67%

set memory to 5-5-5-18
 
temps have maxed at 75C while using prime95 for 50 minutes is that a little high?

sorry to jump in guys.
to OP, what cpu cooler are you using? i know jak731 said that 75.C is ok.
but isn't that a little high for a G0 Q6600 at 3.4GHz?
 
I've posted my settings now quite a few times, in fact so much so they should be stickied :D :p

Here are my settings for 3.6ghz (system in my sig, my chip is a 1.3 VID)...

External Clock - 400
Multiplier - 9x
DRAM Speed - 1:1:25 (DDR2-1000)
PCI-E - 100

CPU - 1.52v (1.42 or so under load)
DDR2 - 2.0v
CPU VTT - 1.23v
MCH - 1.29v
ICH - 1.05v
ICHIO - 1.5v
DDR2 REF - 0%
CPU GTL 0+2 - 67%
CPU GTL 1+3 - 67%

Limit CPUID MaxVal - Disabled
C1E - Auto
Execute Disable Bit - Enabled
Virtualisation - Disabled
EIST - Auto

RAM - By SPD

...you will need to watch the PWM temps. My board is bolt modded and I have a 60mm fan hovering above the PWM area keeping them cool. You may well need the bolt mod if it's not already done.

I also have 2x 40mm fans on the Northbridge, as it can get pretty toasty too.

Bear in mind that the above setting was when I was running 4gb RAM. I am still at 3.6 with 8gb, but have to run the memory on a different divider so that it runs at 800mhz. Any more was too much for the board to cope with. You will likely also need to do this as your RAM is only rated for 800mhz.

Oh and for what it's worth I found that anything above 1.3 for the MCH would cause instabilities. For some reason my board prefered the MCH to be kept fairly low.

I suspect heat may be your enemy tbh. What cooling are you using? What are the PWM temps like under load? Use HWMonitor or Open Hardware Monitor to check the PWM temps.

EDIT - also what PSU are you using? Full system details would help too.

all the cooling is air

i have a noctua nh-u12p cpu cooler with a 120mm fan on it and i have 6 120mm case fans

PSU = Coolmaster Realpower 850W Modular

Gfx = 570GTX

F3 spinpoint 1TB
F1 Spinpoint 500GB

X-Fi Fatality

looking at you sig its almost got the same gear :)

i have CPUID HW monitor but dont see a PWM temp only a percentage (40%).

i dont know what it means
 
Strange that you can't see it. It's clearly shown on mine, under the 'Temperatures' heading there is CPU, System, then PWM.

If your board hasn't had the bolt mod, then it's quite possible that's what is holding you back.

EDIT - funny I just checked and Open Hardware Monitor doesn't show the PWM temps. Strange. Everest will show them as well though if you have it.

EDIT2 - I am using version 1.16 of HWMonitor, and have just checked version 1.17 and it doesn't list the PWM temps. Looks like you need 1.16. Strange that they've taken it out of the newer version?

Older versions are here... http://www.cpuid.com/softwares/hwmonitor/versions-history.html
