Can anyone help me as to why my BIOS is only detecting 8GB of RAM and why I am only using 8GB of RAM according to the task manager?

This sounds like a seating issue probably. Shut down and make sure the RAM is inserted all the way first. It's possible one is just slightly loose.

Are the RAM modules from the exact same pack or were they bought seperately?
Is this a new build that's started with this problem or has the 16GB worked previously?

Agreed with above seating could be the simplest solution.

Already that seating them again multiple times. This is a kit, it came in a pair of 2. Kit is supported by my MOBO and CPU. I tried clearing CMOS, reinstalling my CPU, you name it. This is a brand new memory kit and I actually bought another brand new memory kit to see if the memory was faulty. Both kits had the same problem. Other kit I bought and still have here next to me is the
G.Skill Trident Z RGB F4-3200C16D-16GTZR

Does each RAM module work by itself in each slot?

There were some issues with the TrindentZ pair, I'll explain later. Going to try the HyperX seperately right now.

So both of the HyperX sticks worked and booted up just fine when in the A2 slot, then I tried both of the sticks in B2, PC booted up but no screen was given.

What about the other 2 slots? Or is it just one slot?

Sometimes excess pressure from the CPU cooler can make RAM slots fault - quite commonly the 2 slots furthest away from the CPU. Just relieving a bit of CPU cooler pressure often resolves this problem.

 

[Thomaszz]

With my memory kit it is not recommended to use the A1 and B1 slots. By relieving pressure do you mean loosening the screws of the CPU cooler a little bit?

Is this the motherboard manual?
If so don't worry, it's just to get it to run dual channel in the right slots to begin with - you're just testing if each slot works. yes when running dual channel you should,always run in the slots as per the MB manual, but just for testing it makes no difference, and won't damage anything.

And yes, but again, I would be more likely to do this if the other slot is also not working, if it's just 1 random slot not working, it's a little less likely.

What cooler are you using?

Cooler that came with my Ryzen 5 2600X CPU so I believe that is an AMD wraith cooler. Will try slot A1 and B1 now.

So both sticks worked in the A1 slot but neither of the sticks worked in the B1 slot (PC booted up but no screen was given).
