I assembled a new Asus pn50 4700u yesterday. The memory is Kingston HyperX Impact 32GB (2x16GB) 2666MHz DDR4 SODIMM RAM HX426S15IB2K2/32.
My Manjaro system only sees 16GB. I have reinstalled the ram with the same result. The BIOS, as far as I can tell, doesn’t have any setting for RAM. While some HyperX sticks are on the Asus compatiblity list, this one isn’t. I have read that Ryzen is fussy with ram.
I don’t know if this is a BIOS problem, a RAM problem or a linux problem. Can anyone point me in the right direction?
Hi
could you post the output of:
sudo dmidecode -t memory
and
free -h
?

Hello,
It seems that your bank 0 has a kingston 16mb ddr4 module, But when you look at the other slot, it clearly states that the other module is unknown and under memory devices it says there is no module. It doesn’t even show who the maker of the simm is.
Make sure they are firmly in the slot and that they are a matched set from the same manufacturer Kingston. If the second one is bad. call the manufacturer and have them send you a new one

Strange… the UEFI says here that no module is installed on Channel B???
Also fully agree with @yawanathan
Take the second module and put it in the first slot and see if it recognizes it. Also, what does it say in the bios?
Just FYI, Kingston has one of the best warranties in the US at least. It’s super easy to get a new module sent to you, as they have a lifetime warranty on their memory.
I swapped the positions of the ram sticks and Hey presto!
