Overclocking my Q9400 quad 2.66 problem

post #1 of 20
Thread Starter 
Hi all recently I have tried to boost my system cpu but with no success, I`ve tried 3 times changing different things like fsb,ram settings,voltage but the only thing i got was my pc didnt want to start after saving the settings,I have recovered it every time with the removal of the motherboard battery i think it was called cmos or something.Now cpu-z shows my cpu is 1998 ghz not 2.66 like it used to be is this a problem? My pc has Intel Q9400 cpu and the motherboard is ECS p43t-a2. My goal is to make the cpu from 2.66 to 3.2-3.4 Ghz Thank you in advance,I hope you can help me. Here are the images of my bios menu:

What hardware do you use exactly.

Memory? PSU? etc.

For adding your system specs into your sig rig CLICK HERE..

Now for your worrying about your CPU running @ 2GHz there's nothing wrong..

Your CPU is sipley downclocking when it's not in use but under load it will run at 2.6GHz..

If you disable C1E and SpeedStep (or EIST in your BIOS) in BIOS and set your CPU multiplier to 8 then your CPU would be running @ 2.6GHz all the time..

EDIT: Now for your motherboard it has very limited OC optionds in BIOS (Vcore and RAM voltage but no NB voltage or FSB voltage)..

Set your RAM frequency to 667MHz ,that's becouse your ram is 800MHz and by upping FSB it would run over it's rated speed,but this way it would not be a limiting factor//

Then start upping FSB (CPU Overclock. freq) by 10MHz..

Also upp Core voltage when it fails to boot..

If Vcore doesn't help then your motherboard is limiting you..

CHEERS..

I did everything you said, I managed to go to 383fsb here are the results: 83544142.jpg

whenever i try to go beyond that 403fsb my pv freezes i tried to +vcore with the first two options 057 and 097 but,no success here is the image 12032011060.th.jpg

That's great man..wave2.gif

Test your OC with Intel Burn Test for 20 runs with max RAM dedicated for the test and if you pass then you're good to go..

NOTICE: Your CPU will get pretty hot in IBT test so make sure that core temperatures are under 75C all the time..

CHEERS..

do you think we can push my cpu overclocking more for 3.2 or 3.4-5 maybe? By the way +rep and thanks for the help so far man biggrin.gif

3.6GHz (450MHz FSB) would be easily achieveble but on a P45 motherboard..

Some P45 mobos like Gigabyte EP45-UD3P or a Asus P5Q Deluxe could even take it to 4GHz (500MHz FSB)

On your motherboard that's what you'll get..redface.gif

Most P43 motherboards cannot do more than 400MHz FSB with a Quad Core CPU(420MHz if you have a really good one like Gigabyte,or Asus but still not 100% guarantied)

Try to set PCIE frequency to 103MHz - 105MHz and see if that helps you to push a bit more..

As on some P43 motherboards that really helps..

CHEERS..

KingT, the King has spoken biggrin.gif

Anyway, agree with what he says here... 3.2GHz should be possible. Anything after 400FSB on that cheap motherboard is not guaranteed.

I have a crappy P5QL-CM (G43) which hit a wall with my Q9400 at 361FSB. Anything past that, and it refused to boot. I was pretty fast ripping that system apart and rebuiding my old GA-P35 DS3R full ATX system back again. Which will do Q9400@3.6GHz (450FSB x9).

Also, do not go to far on the V-core. From the pictures of this review it looks to have a crappy 3-Phase CPU power regulation. I doubt you will get to the point you would need very high V-core anyway. Due to your motherboard will FSB limit you long before that.

My Q9400 only needs about 1.25 V-core at full load for 3.6GHz.

Nah tried it,no success I guess 383 is the maximum..
