Hey fella.
Yeh, I checked that before buying the board and even though only 3G Corsair is supported (like DM has) I figured it would support 12G @ 1600Mhz.
I was wrong! lol
At a stretch i can live with it running @ 1333Mhz but it feels like I now have under-used RAM and an under-performing board. It may not be the case but it feels like it.
I'll dip my toe in the RMA water but it's with SCAN in the UK and they have a really convoluted process.
