Win 10 64bit System info and BIOS both showing only 8gb ram after upgrading with 2x8gb. Msi pc mate z97 mobo. I have tried utilizing slots 1+3 as well as 2+4 to keep the dual channel. Any suggestions on what else i could try? Yes the sticks are seated completely in and they are new sticks so I wouldn't think that a stick could have already gone bad.
