i have an AMD Ryzen 5 2600 CPU (ref: YD2600BBAFBOX) and it works great with 16GB DDRAM (2666Mhz) in 2x8Gb kit or 1x16Gb, but when i upgrade it to 32Gb whatever the motherboard is or the memory, every time it freeze.


Before i had a ASUS TUF B450M motherboard with 4x8GB HyperX 2666Mhz and now i changed the MB for an ASRock B450 Pro 4 with 2x16GB Hyper 2666Mhz (kit ref: HX426C16FB3K2/32) and it freeze in the bios, or under Ubuntu 19.10, or under WIndows 10 x64.


Firstly i thought the memory and MB were the root of my issue but since i changed them i do not understand.

Please can you tell me if the CPU REALLY supports 4 slots (to max 64GB as documentation tells) and if there are some issue with 32GB DDRAM4 in 2666Mhz ?

I mounted thousands of computers during 15 years as PC assembler and i've never had such issue. It's weird.
