Meta has found a way to reuse older DDR4 memory in its newest DDR5 servers instead of throwing it away.

The company built a custom chip called Vistara that allows older DDR4 memory to work with modern DDR5 servers.

The slower DDR4 memory stores data that isn’t needed as often, while the faster DDR5 memory handles tasks that need the best performance.

Meta says this lowers costs, reduces electronic waste, and makes better use of existing hardware during the global memory shortage.

The technology is only for data centers and AI servers. It is not designed for gaming PCs or consumer computers.
