u know i really wish that i can adjust the gtl value like u guys with the DFI mobo, coz in my gigabyte x38 bios. there isn't much on GTL to play with

Shoved off some vcore.. stable with orthos 2 hours on all 4 cores.. but not IBT stable.. Oh well..

Q9450 C1, 3.75Ghz, 1.256v, IBT stable:


Screenshot shows voltage as 1.288v, but actual load voltage due to vdroop is 1.256v:


4Ghz testing soon when the platform is free =)

thats a wonderful vcore i might say...

need to share some tips r...

how about d temp??

What motherboard and ram?
Not bad at all,dube You really got lucky

Man that's a good vcore for 3.75ghz. Either it's a good chip or the mobo is doing the trick?

Board is Striker 2 Extreme, DDR3-2000 RAM. I think I really got lucky lor, takkan the 790i is -that- good =p

Thanks man. Not many tips, just upped Vcore/Vtt/GTL as usual. Temp is around 80C IBT (though it can go as high as 88C!), Prime 68-70C on a CCF.

Most likely chip kua..

Hmmm everyone is clocking 45nm quaddies so good,
I'll go the opposite direction just because I'm bored


2.2ghz @ 0.96v passed IBT 20 runs


With SpeedStep and C1E enabled + SuperPI 1m

0.96v
Nice

-pWs-

bro, how's the temperature like?

It used to be anywhere from 68 to 73c.
Now its....



EDIT : Just added a zalman 8cm fan to cool my rams, and it gave me a drop to 49c max at load.

Been tweaking here and there for this processor, made my reinstall my vista few times cos it somehow screw up my hard disk indexes while overclock. Gave up trying to break the 4ghz barrier, maybe will do it when I am free for a week


Well this is the screen shot, target at 3.6ghz and below 1.25vcore.



Did IBT 20 runs without problems and also have prime it for few hours without errors.

My max I tried to boost was 475 x 8 which result in 3.8ghz. Managed to let it run stable but anything higher just require damn alot of additional vcore and vNB + vFSb.



Did not spend much time tweaking on Gtl section yet, hopefully tuning Gtl can yield a lower vcore compare to now heh.

ur corsair can hit 530mhz...wow!

Sorry about that, just changed my ram to corsair dominator 8500 (first picture) ..my previous ram xms2 6400 only able to hit the max of 950 mhz , with loose timing of coz ( look at the second picture, that is using xms2 ).

@3.5ghz the temp idle is around 47c, prime load maximum goes to 69c , IBT @ 72c. In an non aircond room.

@3.8ghz the idle temp is around 50c, IBT load goes as high as 80c, prime at 77c. Non aircond room.

what cooler are u using for your Q9450 bro? Your Q9450 seems to be performing almost the same as my recently sold Q9450. mine did 3.5hz comfortably at approx 48c/65c idle/load with prime @ 1.225v.

woah, load at 80c with IBT, sheeeet... i dun even dare touch that temp region. nanti your chip kena fried instantly

Using Sunbeam CCF to cool my CPU currently. Been giving good temperatures so far, but I think it can go better if I can manage my CPU casing cables and airflow properly. Currently trying to lower the vCore , vNB, vTT to as low as possible while making sure to keep it stable @3.5ghz. Last night I managed to drop another 0.1vcore to it, hopefully can still be reduced.

Btw, metsatsu what is your highest clock speed for q9450 ? Is it really possible to break 4.0ghz for q9450 ?

the highest clock i ever managed to get was only 3.6ghz. but not bcoz the chip had reached its limit but i think it was due to my cooler and mobo. even at 3.6ghz was rather shaky. coz my idle temp was like 59c which was 10c more than my 3.5ghz idle temp. 1.325v was needed to bump it from 3.5ghz to 3.6ghz lol.

icemocha n acecombat did it in lyn.....

mine ex only can manage to reach 3.84.....

but only the ones that acecombat did was 1 hour occt stable...

Wonder if can get 4.0ghz IBt stable on 20runs. That would be perfect .. by the way, still trying the highest I can go right now. Heh...

4ghz on air ibt wud be

but wish u the best in trying
