I have a H170-PRO asus mother board.
Original specs
I5-6402P
32gigs ddr4
4x8gigs

New specs
I7-7700k
32gigs of ddr4
4x8gigs
Windows 10 Home edition 64bit

When I upgraded the CPU i had to update the bios. now with new cpu installed and everything working.. The computer is only recognizing 16gigs of ram. I enter the bios, all 4 sticks show. However only 16gigs of total memory. In windows same thing, in speccy, i can see all 4 sticks and 32gigs of ram. However under phycial memory it shows 16. and in the computer info, it only shows 16gigs as well.

I have XPM enabled. and have tried reseating the sticks multiple times.. However, when i seat 2x8 side by side it only reads 8gigs. I have to seat 1 in the first slot and another in the 3rd slot for it to read 16gigs. So im assuming for some reason its in dual channel mode.

Did this. All sticks work in any configuration... 2x or 1x. just not 4x
