I'm on a X48 board. (Rampage Extreme)

I have a feeling the Diablo's aren't great, 900 7-6-5 should be possible with 1.9V with good GTR.

I'm puzzled by the Crucials, i'd really expected them to be GTS or GTR but they were nothing like GTS/GTR more like how Samsung HCF0 behaves. (don't like tight timings <cas 8)
