Here are the settings that my Q9400 is stable @3.6Ghz. Like to have your ideas if they are good for 24/7 use ?

I have been using it @3.4Ghz for a long time by now since I thought my settings for 3.4Ghz were safer but now thinking to get it to 3.6Ghz. Your ideas are important to help me decide.

Temps are hitting low 70C's max when IBT is runnin with these settings. When idle in windows temps are low 30C's even high 20C's. With Prime95 high 50C's rarely 60C's.

Actually mostly the nb voltage and fsb term voltages with these settings below seems high to me and they are keeping me away from running it @3.6Ghz....

What do you guys think ?

Any ideas and suggestions on these settings are welcome...

Cpu Ratio : 8.0
Fsb Frequency : 450
Fsb Strap to North Bridge : 266
Dram Frequency : Ddr3 - 1353 9-9-9-25
PCI-E Frequency : 100
Cpu Voltage : 1.375v ( 1.34v idle in windows and 1.31v underload )
Cpu PLL : 1.54v
Fsb Termination : 1.36v ( yellow in bios )
NB Voltage : 1.49 ( yellow in bios )
Dram Voltage : 1.60
SB Voltage : Auto
Clock-Over Charging Voltage : Auto
Cpu Gtl Ref : x0.63
Nb Gtl Ref : x0.67
Load Line Callibration : Disabled

Looks good. I think you can use it 24/7. I don't usually touch the CPU PPL Voltage.

really depends on temps over the long haul

I heard that you shouldn't go over 1.45v on nb and 1.40v on fsb term volts with 45nm Quads. Do you think nb volt is too high and fsb term volt is too close to the edge ? In windows idle temps are around 29 - 30 - 31- 35 and when I run some benchmark or any app I've never seen them go over 50C's...But when it comes to stress tests temps are like I've mentioned in my first post.

Have you reached your lowest vcore possible yet?

what happens when you run lower nb?
fsb term?

basically....have you tried getting to your lowest voltages on your settings?

it seems you still have them kinda high like your just trying to get it stable

When I try to lower values on nb and fsb term I can't even get into windows and system frezees at loading screen..

Well, when I touch any of these settings it looses stability @3.6Ghz.

However, I've managed to get it very stable @3.57Ghz with settings below which actually seems fine to me...What do you guys think for 7/24 use with these settings.

I have set the cpu gtl and nb gtl reference settings to Auto.

Cpu Ratio : 8.0
Fsb Frequency : 444
Fsb Strap to North Bridge : 266
Dram Frequency : Ddr3 - 1335
Cpu Voltage : 1.350v ( in windows 1.32v idle 1.28-1.29 underload )
Cpu PLL : 1.52v
Fsb Termination : 1.34v ( yellow in bios )
NB Voltage : 1.41v
Dram Voltage : 1.60v
Cpu Gtl Ref : Auto
Nb Gtl Ref : Auto
Load Line Callibration : Disabled

Btw, your settings are good for 24/7 use.

Ok, I have just set the fsb frequency to 445 and lowered the fsb term voltage to 1.32v from 1.34v ( anything lower can't finish 3D Mark 06 ) and nb voltage to 1.39 from 1.42v and ran IBT. Results and final settings are below.

Any comments are more than welcome.

Temps that never exceed 58C in Prime95 with very same settings reached max of 66C when IBT is running. But we all know IBT is crazy about temps. Idle temps are 26 - 28 -29 -34.

I love this chip wish had x9 multi choice too...

Cpu Ratio : 8.0

Even 20 succesful runs of IBT 6h of Prime95 and 2h OCCT mix stable with settings in my message above I had some issues like freezes, crashes with few games. Upping the nb volt to 1.41 from 1.39 and fsb term volt to 1.34 from 1.32 solved these problems but why such thing happen ?

It passed those stress tests with 1.39v nb and 1.32v fsb term voltages but problems in games and can't help but ask why ?

These tests are not trustworthy ? Further than that when I powered on my pc this morning it was idle on desktop and doing nothing but when I got back I saw these horizontal colored lines all around the screen and system was freezed. So I restarted it and reverted everything back to 3.42Ghz settings but really curious about how come it passes all stress tests with these settings and then such problems occur ?

Any help and ideas would be much appreciated.
