Hi all,
I just installed my G.SKILL 2x16GB DDR4 RAM sticks on my ASRock B450M-HDV R4.0 and both sticks show up on A1 and B1 on the BIOS but it's only running in Single Channel memory mode and thus only 16GB is usable.

Any ideas on what I'm doing incorrectly here? Any help is appreciated.

so the motherboard only have 2 ram slot
using only 1 stick. test each slot to see if might be 1 is not working
Both slots work. Previously they were being used for 2x4 and they posted as 8GB and all of it was usable.
Now, both sticks post in BIOS but only one gets used while other is "Hardware Reserved" under Task Manager
