I got an old pc that was built using a kit of (2 x CORSAIR XMS2 PC2-6400 1GB) working at 1.8volts .
Since I recently upgraded my Windows 7 32bits to Windows 7 64bits I tought I needed an extra pair of ram sticks.
Bought another new, out of package, kit of ram sticks same model and capacity except didnt noticed that they work at 1.9volts.
Tried:
1)Before taking notice at the voltage and using all (4 x CORSAIR XMS2 PC2-6400 1GB) pc would not POST, and no video signal nor beeping
2)Used only the new kit of (2 x CORSAIR XMS2 PC2-6400 1GB) 1.9volts and got same result as above.
3)Reseated the old kit (2 x CORSAIR XMS2 PC2-6400 1GB) 1.8 volts and the PC booted normally.
Questions:
The thing that got me bothered was that BIOS is in Auto DDR2 Voltage Control so when I tried the new kit it should had adjusted to the new voltage alone. Is that how it works perhaps?
If I scale up in BIOS the DDR2 voltage control from 1.8v to 1.9v maybe can I get the PC to boot properly with both kits for a total of 4GB ?
My motherboard (ASUS M2A-VM HDMI) supports up to 2.10volts on the DDR2 dimms
I havent tried anything else.
Thanks in advance for the help.
