Question MSI B350 Tomahawk 32GB RAM installed 16GB recognized

[beamkiller]

Hi,

I have updated my PC from 16GB to 32GB of RAM. But the BIOS shows only 16GB Physical Memory is available. The BIOS recognize all the slots and shows the adaquate data about them.
Aida 64, CPU-Z also shows the correct information about RAM.

I have tried everything in BIOS, change voltage to 1.35V, XMP profiles - PC wont even boot up.
Reseat all the memory modules. The default was 2nd and 4th slot, these are v4.32 the newest are v 5.30. There was a combination when PC even didn't get to the POST screen (just black screen).
All the RAMs are the same - Corsair LPX Vengeance DDR4 3000Mhz 8GB.
I have updated BIOS to the newest stable version.
Windows Memory Diagnostic didnt found any error.
MemTest 86 didnt find any error.

Has anyone any idea what should I try?

The RAMs are:

From your screenshots, I can tell you're on a Ryzen 5 1600 but you forgot to mention other details. We ask that users post their specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS: If Windows 10, which version

and the BIOS version that you're on. Given how you've mentioned having two kits, meaning two sticks are v4.32 and two sticks are v5.30, do each kit work as a pair? If so, see if flashing the BIOS with the latest, manually, changes the issue.

If not, then you're going to have to resort to getting the same kit again(either v5.3 or v4.32.

CPU-Z shows memory part number to be that of 2x8GB kits.

Memory is guaranteed in the form sold by Corsair. Use of multiple kits have no guarantee to be compatible together. You are free to do your own compatibility testing with no guarantees if you choose to make such combinations - multiple kits of memory.
