Hi,

Having some problems getting 3.4GHZ prime stable.

Firstly ive got 3.2 stable using these settings:-

360x9
Ram 1:1 (720)
cpu v: 1.4v
ram by spd
ddr2 v: auto
mch: 1.37

Now this is stable and pretty cool, max core temp is 61. And the IP35's infamous PWM temps only hit 55. The core voltage under load is 1.34-1.36v.

Now my chip has a pretty high VID (1.325) but is the G0 stepping revision.

So I have been trying all evening to get 3.4 stable.

Using:-

380x9
ram 1:1 (760)

Now Ive been steadily bumping the vcore all the way from 1.4 to 1.51 and it still blue screens after 5 mins of prime.

The higher the volts go the longer prime will run, however my PWM temps seem to reach 60 just before it blue screens. Temps @ 1.51 v were under 70.

So, is it my PWM that is holding me back? My cooling? Settings?

Ideas would be appreciated! :D
 
what ram are you using, and is it getting the right voltage ?

have you tried any settings between 360 & 380 ?

if you drop the side off the case does the system run cooler, hopefully help keep the pwm temps down a bit.
 
what are your other voltages set at?

you could increase the mch voltage to help stability if its set low

Hi,

My ram is Kingston KHX8500D2K2/4G which runs at 5-5-5-15 2.2-2.3V

I have been running it at 2.2 as I heard this board can overvolt the ram. Currently its on Auto, ram is currently on SPD also.

I will try between 360-380 tonight to find where it gets unstable, and take my side pannel off. Although my case has pretty decent airflow with 6 yate loons.

Im thinking of doing the bolt mod on this board and maybe getting some 60mm fans for PWM and NB.

Yeah, it is at 1.37 for 3.2GHZ and I bumped it up to 1.41. Not sure how high to try taking it?
 
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. You may well need the bolt mod if it's not already done... http://www.xtremesystems.org/forums/...&postcount=751

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.

EDIT - 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.

Hi Diggsy

I was hoping you would see my thread :)

I remember the last time I made a thread RE Q6600 OC'ing you were a great help. I finaly got the PRO version of the board.

From searching I found your settings and tried them exactly but it Blue screens after a few mins on prime.

Im going bolt mod the heatsinks at the weekend or at least replace the TIM with MX-3 and remove the heatpipe.

Im currently running my ram @2.3v and ive entered the settings manualy, did you find that any more/less stable?
 
Hey there, always happy to help out :)

I found my memory likes to run at 2.0v and no more, anything above that just seemed to leave the system flaky.

You might want to try dropping the voltage to see what happens.

As for the actual timings, I just left it at SPD and it hasn't given me any hassle at all.

It's quite likely your PWM temps are rocketing on you when you tried 3.6, as it puts a lot of strain on them. You should definately get the bolt mod done and get a fan on there to help keep them cool.

Also, I meant to ask, but what BIOS revision are you running?
 
My ram is supposed to run @ 2.2-2.3, I thought if I gave it less v it would be unstable surely? I will give it a try though.

Like I said in my OP the PWM temps shot up to 60 then it blue screens when trying 3.6

Cpuz says the BIOS version is 6.00 PG

Cheers
 
CPU-Z does not show you the BIOS revision, merely the Award version. You need to check on boot up, look at the bottom of the POST screen for the last 2 digits.

I know your RAM can run at those voltages, but it might run better slightly lower, and will certainly run a fair bit cooler too. Don't forget this board overvolts the RAM slightly too.
 
IIRC 17 is the one I am running, and pretty much the best (and most recent thats not a beta) bios version.

Perhaps once you get the PWM cooling sorted you will have more luck with the OC
 
you got any pics of the pwm mod yourself?

currently looking at clocking a q6600 too in an abit ip35 pro :)

by the way how are you measuring pwm temps, uguru?

thanks for the link :) have got 3 q6600's, one of them that I'm clocking now has the same VID as yours currently at 1.32 @ 3GHZ. Bootable at 3.5 but can't run any prime small FFT.

Not sure what settings are best to do motherboard wise though.

Yeah, the high VID on my chip is a PITA. Im currently stable at 3.2GHZ with a Vcore of 1.4

Temps are good, load max temp is 61. I just cant seem to get 3.4 properly stable. I hope the PWM mod and the 2 new fans im going to put on my Scythe ninja will make a difference but the CPU may be whats limiting my OC.

3.2 stable is still plenty good :)

Also... 3 Q6600's? If you have one going spare send it my way! :p
 
You done the vdroop mod on the abit? I haven't measured with a multimeter, but just software based cpuz shows 1.26 under stress, its 1.32 in bios and shows as 1.3 in cpuz when idle.

Going to look for some readout points to see the truth!
 
No, Ive not soldered since high school! Ive read about that mod and it seems simple enough but I dont think ill risk it.

How high have you got your OC? Id be interested to know how other high VID chips OC.
