Hey, I have 16GB ram in my PC, but it says only 7.98 GB usable.
How can I solve this issue?

According to the specs -- https://www.asus.com/Motherboards/M5A78LMUSB3/specifications/ That motherboard supports a max of 32GB RAM using 4 slots. That is 8GB per slot. You have a 16GB DIMM in a slot and the motherboard can only access 1/2 of it.

What does this mean? I have 4gb of ram in each slot

Sorry, I misinterpreted the CPU-Z display. I thought it was on SPD tab and showing a single DIMM.

I also was confused since CPU-Z shows single channel mode. That is VERY odd with 4 DIMMs. That also led me to think you had a single 16GB DIMM.

Can you post screenshots from CPU-Z spd section for each module?

Does all the RAM match (same make/model)?

Every RAM is the exact same model

I would have read the same way, BTW. Something seems odd here.

Bent CPU Pins.

Common problem with the FX processors we see it here all the time. Remove your CPU and check all the pins along the outside, if some are bent that manifests itself as this issue.
