Something strange sometime happens with my motherboard when I change NB volts.
I'm using Easy Tune to tweak my settings in windows, and i can change all the voltages fine, except the MCH voltage. If I move up too much, or when really pushing the other voltages, the PC freezes and a shutdown is the only way out. Sometimes it wont even boot after that, and just starts turning itself on and off until I shut it down. I then have to take out my RAMs, pun in another stick of RAM (Another brand/spec) and then it will boot up. Then I can shut down the computer, install my regular rams again, and start all over.
For example, I wanted to really push things so I went from 1.34v til 1.4V MHC and diddnt change anything else. No lock up. I then changed all the other ram settings ( PLL, VTT, Vcore and DRAM). Still no lock up. Then I changed the MHC voltage to 1.58 and it locked up as soon as I hit the "Set" button in ET. And I'm still running at stock frequency btw, only changing volts here.
After a reboot I tried going directly from 1.34V to 1.50V and that gave me a lock up also.
The same thing happens if I change the settings in BIOS. Then there is just no post instead of the lock up. And the computer starts rebooting endlessly.
My setup:
Ep45-UD3P
QX9650
2x1Gb Ballistix DDR2 (D9 chips)
GTX460
Corsair TX750
Tried with W7 64 bit, Win Xp 32 bit and Vista 32it.
Any ideas?
