Hi all,
My PC won't post after I tried setting +0.5Vdimm to my DDR2. I had to clear CMOS for my PC to work again.
My setup at that time was:
FSB: 395Mhz
CPu multiplier: 8x (QX6700)
Vdimm: +0.5
Vcore: 1.375V
Ram Multiplier: 2.5
BIOS: F10
FSB and mch: both +0.1V
After that, it seems that I can't run my FSB at 395Mhz. When i tried to set 395Mhz, it will only detect as 394Mhz. Did i screw up anything?
What causes my PC not being able to POST when i changed my settings? Is it the RAM speed too high? Or my Corsair RAM confirm not able to accept +0.5V? Or Gigabyte motherboard is restricting my RAM Vdimm to be less than +0.5V?
I'm having problem getting my FSB past 400Mhz...but probably that's because i'm setting *8 multiplier and my processor cannot handle too high speed...
Will try to lower my CPU multiplier to *7 and then try increasing my FSB.
Appreciate inputs here: eg. RAM ratio always 1:1 and 2.5 ratio is not recommended. Or never put Vdimm at +0.5?
Thanks!
