Right voltage for ram

[mehcrim]

Hi guys,

Im running 2x2 gigs of Trancend aXe DDR2 1066 ram.
Now my problem is that it is underclocked as my Mobo ( MSI P7N sli platinum )
only supports up to DDR2 800. So its running at that i guess.

I need to know what voltage i should use as it was on 1.90 volts but i kept experiencing lock ups so i dont know if its high enough seeing as the ram is underclocked.

1.9v could be too high at only 800mhz, particularly if you are running on SPD timings.

What timings are you running? If you can drop them, it might become stable at 1.9v

Download CPU-Z (if you haven't got it already) and go to the SPD tab. Take a look at the timings table. Look for a profile which runs at 533 MHz (1066MHz effective). There you'll find the timings and voltage which are proved to be good by the manufacturer to run at 1066MHz. Apply these in the bios.
If there isn't a 1066MHz profile, go to the manufacturer's site and look up your RAM. The timings and voltage should be mentioned in a spec sheet or something like that.
