So I got my stuff and got all put together a couple of days ago but encountered a strange "issue"
Bit of background, my RAM is made up of 4x8GB sticks of Corsair Vengeance 3000MHz, I originally had a 2x8 set and later added another 16GB so 2 sticks are SK Hynix and the latter set are Samsung. Anyway, when the SK kit is in the A2+B2 slots and Samsung filling the other the XMP settings crash the system instantly and can only run at the default 2133MHz but I've switched the Samsung to A2+B2 with the SK in the other slots and it seems perfectly stable using the XMP and I can stress test it happily with no problems so far. Is this a case of RAM going bad or just a strange motherboard/RAM temperamentality?
