Hi, I have just put together a
Asrock b450m pro4
Asus rog strix radeon rtx 570
Ryzen 5 3600
Viper patriot ddr4 3200 16gb (2x8gb)
Corsair 450w bronze 80plus cv450 psu
Hardware installation went fine, however upon boot an issue popped up during boot pmu memory training dimm 0
Ram installed into a2 and b2 slots.
Only 8gb recognised by bios and windows, cpuz sees 16gb.
Only way I have found to fix it is use single channel a1 a2 to get 16gb recognised in windows/bios
I rechecked the cpu pins, all perfect, stock fan wasnt too tight.
Anyway I can check if this is cpu, mobo or ram?so I can send back the correct part to the distributor? Many thanks.
Ps
I have not touched the bios from stock however I did instal amd4 chipset driver package from amd website.
