Introducing Micron's Incredible 256GB DDR5-8800 Sticks

These new DDR5-based MCRDIMMs are specifically designed to work with Intel’s Xeon Scalable ‘Granite Rapids’ CPUs

The total ranks of these modules allow for DDR5-8800 effect data speeds

Micron not only announced a sample of these modules but also showcased them

Micron seems to offer two variations of their 256 GB DDR5-8800 MCRDIMMs

Roughly 20W of power is used by the taller variant, which is expected given that a 128 GB DDR5-8000 RDIMM uses roughly 10W while in DDR5-4800 mode

Dual-rank memory modules called Multiplexer Combined Ranks (MCR) DIMMs include a unique buffer that enables both ranks to function concurrently

This buffer essentially doubles the performance of a single module by enabling the concurrent retrieval of 128 bytes of data from both ranks per clock cycle
