Question Z97X Killer DDR3_A2 & DDR3_B2 - Boot but no display when ram in these slots

[AlexFegan111]

So currently I can get any ram to WORK in DDR3_A1 & DDR3_B1 in dual channel just fine.

But no matter what I do, whether its 1x stick, 2x stick, 3x sticks, 4x sticks.

If they are in DDR3_A2 and/or DDR3_B2

It does not work?

The two red slots work fine with any config but the minute I add anything in them black lanes, the PC will boot but I get no display, even on their own.
How is it possible that they are dead slots if never touched? I feel like this is a recognition issue with the motherboard only supporting dual channels.

I am trying to put my 4x4gb sticks in brand new but no luck with old or new sticks unless its them two red lanes?

pls help so I dont have to buy 2x8gb sticks lol

Even if the slots are not 100% dead, why risk using them.
I wouldn't touch those slots...later on when you save a little cash...you're going to need to buy a new mobo...
