Only half of my 16GB of RAM is showing up on BIOS

[Gursel]

Hello, I built a PC today using ASUS B350F Strix, Ryzen 5 1600 and Corsair Vengeance LED (2x8) CMU16GX4M2C3000C15.

I opened my BIOS menu and saw that PC recognizes just 8GB of RAM but it shows the two eight gigabyte sticks at the memory slots. Then I installed Windows 10 and saw that Windows recognizes the 16GB of RAM but only half of it is usable.

Please help.

Try reseating it.

try each stick alone in the machine and make sure they work

Ram slot faulty ?

Try cleaning the shiny contact point

I tried them and they both work.

install cpu-z, go to memory tab and check what it says

I tried guys but the BIOS just recognizes 8 GB while it recognizes both of the 8 GB dimms are placed.

now put them both back in their respective slots based on where the manual says to put a 2 stick configuration.

if that doesn't work , then purposely put them in the wrong slots and see if it will at least give you an error or if the ram will show up.

Check the mainboard manual for correct configuration of 2 memory sticks.

I checked I'm going to try a different configuration for two slots that I wasn't able to try because of my Wraith Spire blocking the dimm slots.

did you install 32bit Windows 10? (at which point only 4GB would be usable but idek)

I tried but a different 2 stick configuration for dual channel but still half of 16gb is usable.

I installed, it says dual channel 16 GB Ram

in task manager does it show your ram at the bottom as being something like 16000 total?

well you weren't kidding thats one strange problem , task manager says 16gb at the top , then shows 8 as being use able. hmm

if both sticks work separately , and you are 100% sure they are in the correct slots , and you have tried every possible slot combination including the exact opposite slots , then there might be some sort of issue with the board or the bios.

[Shiv78]

That's weird, Task Manager says 8.1GB is 'hardware reserved'... dafuq?

I don't think so maybe because I got unsupported Ryzen memory? 

Also I found other people who had this issue on Reddit.

Can you decrease the hardware reserved memory?

Maybe try updating the bios. Seems like an issue with mobo firmware.

Okay I will flash the BIOS now but I never saw anything about memory at the descriptions though.

But that's resource monitor not task manager of which quoted guy was talking about.

in windows 7 its mb. i assumed windows 10 would be the same. I much like the majority of earth don't use windows 10
