Micron, Meta test LPDDR5X SOCAMM2 modules that use ~1/3 the power of DDR5

Micron and Meta trialled SOCAMM2, a modular LPDDR5X server memory module, using Meta’s DCPerf benchmark. Tests found it uses about one-third the power of DDR5 and accounts for under 7% of total system power. LPDDR5X’s lower voltage and advanced signalling deliver better bandwidth-per-watt. Wider adoption may be constrained by existing memory supply issues and potential diversion of DDR5 production.

• SOCAMM2 LPDDR5X used ~1/3 the power of DDR5 in DCPerf tests
• Module represented under 7% of total system power in the white paper
• Lower operating voltage and signalling improve bandwidth-per-watt
• Supply constraints could limit adoption and affect DDR5 availability
