Coolermaster 460W is more than enough on that processor, even with 3HDD - and the instability is without load at all, so we can't blame the PSU.
If Vcore is up and you adjusted bridges and RAM, then you've probably reached the threshold. Not all processors are created equal.
Besides, are you even sure its stable at 235x12? And you're going from 235 fsb to 250 fsb in one jump?
I recommend you stress test for a few hours as 235x12, and if looks okay, stress test some more, maybe half a day while you're at work/school/out with gf/watching a movie/going clubbing/riding your bike/worki...nm....if you're cool, then adjust the fsb by 5Mhz and try it again.
If your system isn't even stable at 235 after stress testing, then there's no point trying to go up - which is probably why at 250 you can't get far.
If you can't do it in small increments, then stop there. You should be happy with the free performance gain.
And please monitor core temps.
thanks for the guidance. I had tried to up the vcore voltage in the bios to 1.3125v, but when boot into the windows, the cpu-z still showing 1.26-1.288v. as for the fsb i had stressed test (fsb 235 x 12.0) for few hours now and it is working fine in the test as well as playing games. but it can't pass 236 fsb with the voltage set to auto, but if i set it manually the voltage isn't show any changes at all. it will boot pass POST but when come to windows boot screen, it will run a while then restart the window.
do you think i should lower the multiplier to 10.0 to try higher fsb or it will not working as well?
thanks
Added on September 4, 2008, 12:39 pmHi all, one more question regarding the vcore vs vid. i had read some article on this but it is still very confusing to me, i set the cpu voltage in bios at 1.35v but in cpu-z it only show 1.288-1.312v. the intel spec say the vid is between 1.18 - 1.312, so is seeting 1.35v or more in bios okay for the processor?
