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.

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.

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 ?

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...

Haha..the air cooler from you wor.. if cannot make it ..then have to find you already ..
