Ram not detected

[mat1233214]

Hey guys,
So here is my problem, I have a Asus Maximus VIII Hero and a 4X4GB G.Skill Ripjaws F4-3000C15Q-16GVRB and when I use 4 stick on my board it only detect 2 and i have only 8GB on the ''B'' channel and nothing on the ''A'' channel so I tried with the others and it's still not working (not a ram problem i guess). I updated the BIOS and still not working I don't know if it's my motherboard or a BIOS setting  Your help would be appreciated

do you have another board to try the ram on?

[HrutkayMods]

well if it's not the ram, the memory controller for channel A might be bad and the board needs to be RMA'd. check that it is all seated perfectly, I have 2 Intel boards that are really testy on how the ram is inserted

but it sounds like a ram controller might be messed up

sometime mount your cpu to tight or to loose may cause this problem.
