Hi all,

Been playing about with this mobo ive now got hold of, along with a Q6600 GO processor (batch L748A673)

Standard CPU-Z below:

For the life of me I CANNOT get this stable at 3.6ghz. I dont really want anything less. I want to get 3.6ghz or I may as well not bother :(

I have 2 x 2gb DDR2 1066 sticks with 5-5-5-15 2T timings. Timings have been set manually.

The most luck ive had so far is the following:

Usual x9 multi, with 1:1:0 setting RAM to 800mhz

CPU: 1.52v
DDR2: 2v
CPU VTT 1.23v
MCH: 1.29
ICH: 1.05
ICH10: 1.5

With this I can boot into Windows, and start Prime for about 30 seconds. Then Its a BSOD. Sometimes one of the cores will just stop in Prime, with the other three carrying on, then a BSOD.

Any ideas?
 
Try adding abit more on the MCH (north bridge) to see if that helps, as im sure you are going over stock on the mobo. Its worth a shot atleast.
 
Doubt the motherboard is struggling with 400 FSB. I have the same board, and it's not an issue with only very slight NB & SB voltage bumps. To eliminate that, try IBT/Prime at 400x6 and see where you get.

If you can get stable at 400x6, then it's pretty much likely to be a case of just needing more vcore to get to 3.6GHz. You're already putting a lot through that chip, though. Is it just a highish VID CPU that won't do 3.6?

And what are your temps like with that high a vcore? PWM temps in particular with an IP35 board? (It was PWM temps that stopped me putting more than 1.4225 through my old Q6600)
 
My settings for 3.6 (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.

I also have 2x 40mm fans on the Northbridge, as it can get pretty toasty too.
 
Hey Diggsy, was it you did the innovative DVD-case+60mm fan PWM solution for the IP35? That was nicely done, and I'd be interested to know how you attached your 2 40mm fans to the NB heatsink. Just zip-ties?

And which fans? Are they noisy at all? Do they make any noticeable difference?
 
Sorry to hijack this thread, but it seems like my board/cpu doesn't like anything higher than 1.40v vcore. At 1.40v and 9x400 I can boot up and run prime but I get an error on one core, but if I try and bump the vcore up even one notch, my comp reboots as soon as I press start on prime. PWM temps are around 60 most times, and cpu isn't hot either, so I'm a little confused. More voltage to the board doesn't seem to make a difference either. And I can't boot at 8x450 for some reason either, no matter how high I up the voltages.

My specs

Abit IP35-E
Q6600
NH-U12P with 2 Apache Blacks
Silverstone FT02
2x2gb Corsair 6400 CAS 8

Any ideas guys?
 
Cheers for all comments so far.

Had another play around today, even knocked the MCH up to 1.37v...still no joy. Took the chip up to 1.57v....still no joy.

My temps arnt amazing at the moment, im using some cheap crappy paste whilst I await my AS5 to come through. However the chip is cooled by a H50 and isnt going above 65c, and im using an Antec Skeleton, so PWM temps are fine, never gone above 50c

I can get it running great at 3.4ghz.....just cant get nicely rounded number of 3.6ghz.

I am starting to think its the chip tbh....

Grrrrrr

Yeah that was me, thanks :)

The 40mms are Rasurbos, and are indeed attached with cable ties. As for noticable difference, no idea really as there is no way to monitor the NB temp, but it can't hurt to add a little bit of active cooling on there :)

As for noise, at full speed they can be a little whiny, but I run them on my Zalman fan controller at low speed, so never hear them.

If you like I can try to take close pics of my install method the next time the case is out for cleaning, but there are fairly decent pics on my build thread...
