I also tried very lose timing like 9-9-9-25-2t but no change.
The CPU voltage didnīt change anything ( also I know my CPU from my Maximus Extreme - it runs til 4GHz with 1,2V ( effective Volts inclusive V-droop ).
The problem is that it is no biggie to clock with only one dimm.... easy as stealing a babies lollipop

- but as soon as I put my second dimm back on its place, my rigg brings BSOD just like hell.
And the kicker is :
Memtest runs without any errors !
