hello everyone, i got a problem with my ram, i have an asus sabertooth x99 motherboard and when i install the ram 2 on the left and 2 on the right, it only says 16gb eventhough i have 32gb, but when i put them all on th right side, it reads 32gb but it crashes once in awhile, and it says memory_management error

thanks for your time, btw i got 4 dimms 8gb each made by patriot 2133mhz. right now i have them in a1,b1,c1,d1 in my MoBo, but it reads 16gb only, when i check the bios, a1 and b1 dimms slot says N/A, it only shows the one on the right which is c1 and d1, oh and i tried switching the sticks so im pretty sure they all working fine, but i cant figure out why it doesnt work on the left side,, it might be the dimms of the MoBo?
