This is a quote from the article about the Threadripper family of CPUs today. Why would someone populate a motherboard with more RAM than is usable by the system?

"Threadripper features independent dual-channel memory controllers, one per die, that combine to provide quad-channel support with varying data transfer rates (outlined below) based upon memory configurations. The platform supports ECC memory and a functional limit of 256GB of RAM, though it can support up to 2TB of capacity as memory density increases."

Thanks!

I am not sure I understand your question. What do you think is the max amount of ram ram usable by the system? It can theoretically support 128gb per dim slot, so if there comes a time where we can fit 128gb on a single ram stick it will support 1tb of ram across 8 sticks.

EDIT: Actually it would be theoretically 256gb per ram slot, not 128. My mistake.

Currently, the limit is 256GB. As time goes on, and firmware changes, and RAM sticks increase in size...2TB.
Those numbers are relevant to exactly 0 people reading this.
