BIOS wont recognize one of two rams, but can be seen on task manager and speccy

Hey guys, new here. And as the title says, one of my ram sticks is not being detected by the motherboard. In the bios, it only shows 8gb total memory. But the weird thing is whenever I check the task manager, it shows a total of 16GB of memory and the 8gb is reserved. I already tried all possible (afaik) ways to remove the hardware reserved memory.

 

Specs:

Ryzen 5 2600

16 GB HyperX RGB

RTX 2070S

Mortar Titanium B450M (updated to latest bios version)

 

Any ideas how to fix this? is my ram faulty? or is it my motherboard? BTW, this is the 3rd time this happened to me, I'm thinking my mobo is causing the problem.

task manager shows slots used 2 of 4?  
if OS tools detect all of your RAM your BIOS may just have an error reporting, in which case you can either ignore it, or update the BIOS. 

We can't Benchmark like we used to, but we have our ways. One trick is to shove more GPUs in your computer. Like the time I needed to NV-Link, because I needed a higher HeavenBench score, so I did an SLI, which is what they called NV-Link back in the day. So, I decided to put two GPUs in my computer, which was the style at the time. Now, to add another GPU to your computer, costs a new PSU. Now in those days PSUs said OCZ on them, "Gimme 750W OCZs for an SLI" you'd say. Now where were we? Oh yeah, the important thing was that I had two GPUs in my rig, which was the style at the time! They didn't have RGB PSUs at the time, because of the war. The only thing you could get was those big green ones.

Yes, on Speccy, it recognizes 2 sticks. My problem is I can't use the other stick. Only 8 gb is usable atm.

-snip-

under SLOT#1 and SLOT#2 what does it show? 

you can swap the sticks to the other two slots and see if that fixes the issue. you may have a dead slot. 

you can swap the sticks and see if the problem stick is an issue in the other slot. you may have a dead stick. 

you can update the BIOS, you may have a BIOS issue. (this is rather unlikely.)

I'll try swapping the sticks and see if it really is the stick that is causing the problem. It's just weird that if its is dead, then w10 should not recognize that I have a 16gb total of memory right?

correct. it shouldn't detect the stick at all if it's dead. 

i'd see if a slot change helps. be sure to stagger the slots, as that's how most of the dual channels are set up. 
if this doesn't help i'd get the latest BIOS version 7B89vAD. are you sure that's the version you're running?

Have you tried clearing CMOS with battery unplug?
