Q9400@3.6Ghz

[Riverside]

Hi all,

I have Q9400@3.6Ghz. It has been half an hour i am at windows and no lock downs or BSOD's yet. I will try to run OCCT and see what happens.

Here are my settings. Any advice or comments from experienced overclockers woud be welcome.

AI Overclock Tuner - Manual
CPU Ratio Setting - 08.0
FSB Frequency - 450
FSB Strap To North Bridge - Auto
PCIE Frequency - 100
DRAM Frequency - DDR3-1199Mhz
DRAM Command Rate - 2N

CPU Voltage - 1.36250
CPU PLL Voltage - 1.56
FSB Termination Voltage - 1.46

Load Line Callibration - Enabled
CPU Spread Spectrum - Disabled
PCIE Spread Spectrum - Disabled

These are the settings i have changed and their values. Also Speedstep and C1E support disabled. Rated fsb is at 1800Mhz (my mobo supports 1600 max)

Any help or comments would be much appreciated...

Thanks,

Can you lower the voltage? 1.36 is little bit high for an OC on a 45 nm chip... 1.35 is the max you wanna go for a long OC i wouldn't even go into 1.3 volts... but thats just me

Hi thogrom,

What is your other settings in bios ? I have tried 1.30, 1.32, 1.35, and none of them managed to boot into windows...(but passed bios post)

Finally with 1.36 and 1.56 cpu pll and 1.46 fsb termination it did. Running OCCT right now. It has been 20 min. it started.

Heats like 62 58 60 59 . But i saw that it reached 68C's at the beginning. Very high i guess ??

40 minutes of OCCT run and OCCT gives Code 4 Error

please help me to get this thing stable at 3.6ghz

 

[Riverside]

Does anyone know how to get that cpu core voltage down and still succeed ? Is there any settings related to it that will help lowering cpu core voltage and still create a chance to try 3.6Ghz ?

Thogrom how can you manage not to even go into 1.3 volts ? or any other overclockers need your help with this...

Thanks

you have to have a chip with a good VID to use lower voltages to achieve the same results.

VID is random so you won't know what your chip's is until you actually boot it up and look in CPU-Z.

another suggestion.......is the pencil mod

when you OC, to pass tests such as Prime95 and OCCT. you gotta stress out your chip (obviously ), when the cpu is under load, the resistance in the transistors go up resulting in Vdroop. so i guess i'm talking about Vdroop. If your mobo is not up to par with phase regulations, your Vdroop could be really high and that would affect your overall OC and how far you can take your chip.

so the pencil mod will lower your Vdroop which you could then lower the voltage a bit and still have the cpu running stable at hopefully lower voltages.

***research and read up on pencil mod if you're going to do it though as a word of caution.

Hi,

Thanks for the reply. CoreTemp shows my VID as 1.2125v at standart speeds.

But I can't see Cpu-z showing VID anywhere. It shows Core Voltage which changes btw 1.080 and 1.104 at standart speeds ( not overclocked). Are these values are good?

I will look for that pencil mod. Thank you very much for the info.

I dont know if my mobo is up to par with phase regulations but it is Asus P5E3. Just a standart mobo i guess??

At 3.4Ghz it was stable like a rock. Had no issues for 1 week and did everything. Ran those tests, playing games, benchmarking etc...At 3.4 Ghz i did not change any voltage settings they were all at auto and cpu-z were reading 1.28 idle and 1.25-1.26 load. But now with 3.6Ghz it just dont go i dont understand why

Thank you very much...

yeah thats what i was gonna say lol... cpu-z showing vid? wtf!

p5e is a X38, which is... old but new >.> i think its a great mobo anyway, and there should be a pencil mod guide for it somewhere...

 

[Riverside]

i will not consider pencil mod as a solution since i heard that its to the way very risky..

Guess for now i'll just forget about 3.6ghz and stick with 3.4ghz but I also need to optimize settings for 3.4ghz. I will try to set voltages manually for 3.4ghz and thinking to start with 1.25v and see what happens.

Any advice at this point is extremely welcome...

 

[aznguy0028]

oh sorry, typo on my part. i meant CoreTemp

 

[V3NOM]

well imo pencil mods arent really risky... my worry is the graphite just wears off after while

 

[Riverside]

Well, it looks like rock stable at 3.4Ghz with core voltage 1.23v (vdroop 1.20v) settings below but I have no idea about cpu pll, fsb termination, llc and spread spectrum settings. I just set these to the values below but would you advice something else ?

Also since my dimms are 1333mhz can I push them to work at 1361 mhz ? Do I need to set voltage settings for dram too ? Thanks... heats are like load 50C max when idle 34 max

Hi, iv got the asus P5E3 and the q9400 like you. myn is the premium p5e3, and it has the x48 chip set. i can get into windows fine with 3.6, and ran 3dmark06 once, got 18500 but it wasnt stable, almost. so i knocked up the vcore and pill a notch and testing now. my only concern is the temps. got 2 crank my fans up full, noisy, to keep them below 65 c. how hot is to hot? and what is this pill voltage, never herd of it til this forum.

vcore inn windows, runing prime = 1.32
vcore in bios, i think it was 1.34 but not sure
this cpu pill voltage 1.54
NB = 1.55 i think

 

[cadder]

I'm running my Q9400 at 3.4.
CPUZ says core voltage 1.232V
Coretemp says VID 1.175v

I tested it for a little while at 3.76GHz with no problems.

hi riverside, i think i hav worked out our problem, the asus p5e3 fsb is rated to 1600mhz, having the q9400 at 3.6 equates the fsb = 1800mhz. iv messed about with the voltage on the cpu and now believe that the issue with 3.6 is due to the mobo. i am going 2 play with the nb voltage 2moro after noon and all post my results.
hav you gone any further?

TIM, you do know you are asking a question on a 5 month old thread, don't you.

 

[Guest]

haha, no.

 

[sk8hockey]

i overclocked my q9400 to 4Ghz stable running at 50C max load
mobo v1.55
cpu v1.6
can anything go wrong even with the low temp?

 

[optiprimox]

what are your temps? I'm guessing your using w/c'n?

 

[sk8hockey]

50 degrees celcius and using fan cooling Noctua NH-C12P with Ultra Kaze 3000RPM Fan

 

[optiprimox]

wow thats crazt low for air - at 1.6v? nice...

 

[Guest]

Hello all.

My overclock is the same as sk8hockey .

My Q9400 needs 1.6v to be stable.

Temps around 35-45C idle, 70C max.
