well all failed frown.gif

and what is the stock vcore for this cpu ? 1.2v ?

Sorry to hear about that.

If you set the vcore to Auto or Normal isn't there a line that says what it is?

Loading CPU-Z and putting some load on the CPU at stock settings should give you a fairly good idea what it is.

It can vary, here is the value range: http://ark.intel.com/products/35428/Intel-Core2-Quad-Processor-Q9650-12M-Cache-3_00-GHz-1333-MHz-FSB


One question: did you try overclocking by just raising the FSB and keeping the voltage at stock? How far did you manage to get it?

well i got that around 3.4ghz on auto but i heard that i should not put it on auto idk

and default should be 1.246-1.256 then on full load and 1.12v on min and 1.280v max 3ghz

don't forget to play with the other voltages. GTL reference voltages and northbridge voltages etc, it's been a while so I can't quite remember all the settings that I used to get my old Q9550 to 4ghz at 1.36v but GTL refs made all the difference in stability. I had an Asus P5Q Deluxe which was one of the better P45 boards though, so I'm not even sure if you can change those settings on your board.

this post is similar to my settings for 4ghz on my Q9550, http://www.overclock.net/t/410403/p5q-deluxe-q9550-4ghz/0_100#post_4947831 it applies to your's as well but won't need to push things as far, just gives you an indication of what voltages need to be changed. don;t do this unless you are aware of the risks, and accept the fact that your mobo and PSU may not be able to handle it, 3.6ghz should be possible though. (just a note Q9650 and 9550 have diff multi, so yours is .5 higher multi I think, so don't go applying 471FSB for giggles tongue.gif unless you want smoke and fire)

your FSB voltage, PLL voltage and NB voltage can probably be kept lower than this, and your CPU cooling may not be up to 1.36v+ (I was on custom water cooling, max temps in high 50"s *c) with your other voltages dialled in though you should be able to drop you vcore to 1.3ish i think. Also I had massive problems getting an overclock stable with 4 sticks of ram in. 2 sticks of ram is rock solid, 4 sticks is unpredicatable, sometimes fine, sometimes won;t even boot. try it with just 2 sticks of ram, and play with all your GTL refs and NB voltages etc

I dont have that option frown.gif PLL voltage

But thank you i will try that out

well i tried anything around 1.12 to 1.36v for 3.4 and 3.6 with different straps thou ( i have not tried lower voltages with 400 strap )
i am wondering what if i change other voltages like VTT NB etc ?
all of those voltages are on lowest possible i just increased the NB voltage from 1.10 to 1.15 thats all

try NB voltage at 1.25v. I think my NB was at 1.35v for 4ghz. Don't worry about PLL not being available. the main thing is to get those GTL refs right, you will have to try various settings on all of the GTL refs to test stability. What is your FSB Termination voltage at? is that VTT on your motherboard?

You won;t be able to lower your Vcore until you reach stability through the other voltages, so just set Vcore at 1.36v and tune the other voltages until it is stable, first set your NB at 1.25-1.35v, then figure out your VTT, perhaps 1.25-1.35v for that too, then try various GTL ref voltages, after you find stability try to lower your Vcore down at 0.01v at a time.

what is GTL refs ? well my max NB voltage is 1.25 (1.10 1.15 1.20 1.25) and for VTT 1.20v and 1.30v thats all

well i need to get some rest biggrin.gif

i will update you guys tomorrow

Thank you all for your helps <3

I think you guys are overestimating his motherboard. This might help:

Try the VTT n NB voltages. Without GTL refs you will be very limited. You wanna buy my P5Q Deluxe? Haha
