I'm thinking to buy new RAM (for Lenovo 320 15AST, motherboard is LNVNB161216).
I had 4GB, I need 8GB.
My current RAM is m471a5143sb1 2400Mhz, CAS (CL) 17, PC19200.
I was looking at two with such specs:
Crucial [CT8G4SFD8213] 2133 Mhz, PC17000, 15-15-15-36
Patriot Signature [PSD48G240081S] 2400 Mhz, PC19200, 17.
First is a bit cheaper, has frequency that no more that baseboard provides, lower latency, but lower PC (also I'm not sure which PC my baseboard provides).
