DFI DK X48-T2RSB-Plus + D9 GMH + DICE

[CryptiK]

I was using 3v on AIR (ambient was about 6°C) for about 3h without killing... That was on Crucial value (D9 GMH) and with Cellshock (D9 GKX), so you have space to raise vdimm

3.1-3.2v on a good air cooling and 3.3v on DICE ( maximum available voltage ) .

I didn't have any problem until now with these voltages ( of course not stable but you could get validation ) .

Btw , if your modules got problem put them in the freezer for a few hours , it'll be ok again ! ( I tested more than 10 times and it worked ! )

try to put DICE directly in front of chips on the Heat Spreader .

And also some chips don't like high vdimm, so test it and you'll know it

OK thanks for the info. Good to know I should have more headroom. Most I've used on air was 2.78v while doing some SPI32M runs, and the sticks were still fine after hours of use. I've never killed any ram so I haven't needed to freeze it, but I hope it works for me if it comes to that.

I do also definitely have to make better pots so the DICE sits in front of the IC's, it was only touching the top edge. That should help get some more MHz out of them.
