Possible RAM incompatibility

I just bought my new pc and built it and it shows some RAM problem, when starting the pc with ram installed on slot 2 and 4 (as suggested in the mobo manual) the computer does not boot, if I place the ram on slot 3 and 4, it boots but it fails to install windows 64bit, I can only install windows 32bit, but it limits my usable ram to 2,2gb (i have 16 gbs).
I am not sure if it is ram incompatibility or if the slots on the motherboard are actually damaged, can anyone help me on this? Thanks


Motherboard: MSI Z170A Gaming M5
Ram: Corsair Vengeance 16 gb ddr4 lpx (8*2)

You should hear a nice click when it's inserted properly. It is far and away the most common RAm problem, that's why everybody suggests checking it. If you were using an infective technique, it would keep giving you trouble.
That said, it could also be one bad stick. Try installing OS with just one stick in, or otherwise test each one.

Well I actually had a similar problem a couple months back when I upgraded from 8gb of ram to 16gb. It turned out that I simply had not pressed the ram in firmly enough. Just double check and make sure your ram is very firmly seated and locked in. You don't want to break your motherboard of course so don't take a hammer to it or anything, but don't be afraid to apply a bit of pressure, those things can put up a fight. Your ram is not incompatible by the way, ddr4 should work just fine with a z170 board, so I would highly suggest just making sure it's all in there correctly.

i've tried many times many possible combinations of putting ram in several slots so I doubt that it is not installed correctly, also, the pc does actually start working, the fans start spinning and the LED's start working so I assume the ram is correctly installed, can it not be anything else? My ram has 2133 mhz speed and my motherboard supports a minimum of 2133 mhz, supposely it should work, but can it be from that?

Thanks

The ram speed isn't the problem that's something that I'm certain about. If you're convinced that it's not a problem with how the ram is actually seated, then once you get it booted up again check your BIOS settings to see if anything seems out of the ordinary. If you've changed any of the settings in the past, try resetting the BIOS settings to default and restart it. If it still doesn't work, try reseating the ram one more time in the supposedly default position. If it doesn't work then, try googling to see if other people have the same problem, that's what I did to solve my problem at least.
