DDR5
Also: DDR5 RAM
The current kind of computer memory. Install it in matched pairs so it runs at full speed.
The fuller definition
DDR5 is the current generation of desktop memory. Its speed is quoted in megatransfers per second, and two matched sticks in the right slots run in dual-channel mode for more bandwidth.

System RAM is far slower than graphics memory; it is where overflow layers or MoE experts live.
