Just put a system together and it only recognizes half of the installed ram. 32gb installed, only16gb is showing in windows and bios. Tried m each stick individually and In each slot Anyone have know what could be causing this. Specs attached.

You have two sticks of compatible RAM and two sticks of incompatible.

Remove the two sticks of 2133MHz RAM.

Put one stick of the 1600MHz RAM in slot A2 and the other in B2, the blue slots.

Reassemble, restart and enter the BIOS.

Restore the MBs default factory settings in the BIOS, they are sometimes listed as one of the following " factory defaults" “most stable” or on newer boards “optimized” please note that if you have both the “most stable” and the “optimized” options in the BIOS you should choose the most stable" option as in this instance the “optimized” settings are a form of overclocking that can cause instability.

Save the new settings, exit the BIOS, restart the computer and access the BIOS, check the amount of RAM then post back with an update for us once you have done this.

Mismatching RAM never works and being that the OP revisited the forum but chose not to reply this thread will be marked and closed.
