That just means the kits came as a 16GB or 32GB kit. While it's technically not on the supported list, they don't list 2 kit combinations, which yours would be. They're likely the same sticks, just sold as a set of 2 while the supported ones are sold as a set of 4.
I'm having the same issue, I think. HyperX and UD5(Thunderbolt version though) as well, but my 32GB Cl15 2666 kit is supported. I haven't gone so far as testing the channel individually with 2 sticks, still running memtest, but it does the same things as yours when I try to boot with 4 sticks.
. Same issue. Just stopped the test to check..Edited by TheContact - 10/17/15 at 5:43pm
