What am I looking for in RAM

[Alex Adamson]

I need new RAM and I'm wondering what I'm looking for. What's important specs when buying them and what compatibility issues do I need to worry about?

EDIT: can a DDR4 motherboard use DDR3 RAM?

What are your system specs?

The new Ryzen systems benefit from faster RAM speeds 3000mhz+, not to sure about intel CPU's they may only have a slight increase of performance...

As for DDR3 in a DDR4 Board, the answer is no sorry

Yeah it is Intel, i5 4460
