Z97 Mobo > cannot get more than 8GB ram to work!?

I havent done a lot of touching at all to this pc since I built it in 2015. Trying to upgrade from 8gb ram (2x4gb) to 16gb ram (4x4gb) got them cheap. 

 

Currently my two ram sticks and MY TWO of 4 NEW ones only work in the two RED slots. No matter the ram, the two black slots do not work. 

 

The pc will turn on too any ram configuration I put in that involves 4 sticks or even 3 but NO display after clearing the CMOS several times. 

So only each 4gb stick (no matter the brand) work in ONLY the two red slots. 

 

WHYYYYYYYYYYYYY 

I have no beeper in her so I cannot hear what it is but its pretty obvious to some extent. The two black slots dont even work on there own? Do I need to do something in the BIOS? 

Its the asrock z97x killer mobo

Sounds like your memory is fine, it's possible the RAM slots are dead.

I dont understand how that can happen, DDR3_A1 & DDR3_B1 work 

DDR3_A2 & DDR3_B2 do not work

Defects in the motherboard, it's very rare but it does happen.

Is there nothing in the bios than can help me troubleshoot? Like how can I actually prove they are dead slots without assuming if something doesnt work in it then its dead, this is not enough for me lol

I am not aware of any setting in any BIOS that would disable RAM slots like that. My only other suggest is to swap out for a differ Z97 series CPU, as it's minutely possible your CPU cant accept the second channel of ram due to a defect in the CPU.
