Server Memory Upgrade

This 64GB DDR5 ECC RDIMM module is built for Supermicro GPU A+ Server AS-8126GS-NB3RT platforms. Registered buffering and error-correcting code protect data integrity in multi-socket workloads. The single-stick design leaves remaining slots open for future expansion.

Sustained Load Behaviour

Operating at 1.1V with CL52 latency, the module maintains its 6400MHz transfer rate during extended compute tasks. The 2Rx4 organisation spreads accesses across two ranks to keep bandwidth stable under continuous memory pressure. Samsung, Micron or Hynix die selections are validated for server-grade endurance.

Compatibility Decider

The part number MR51200-924K1 confirms qualified operation only with the listed Supermicro GPU A+ Server AS-8126GS-NB3RT system. Builders targeting other motherboards or workstation platforms must verify qualification separately before purchase.

Questions about this item

How much power does the 1.1 V 6400 MHz DDR5 module draw when the server runs continuously?

The module operates at 1.1 V, which is the standard DDR5 voltage, and its 2Rx4 organisation spreads the load across ranks to keep per-pin current moderate during sustained workloads.

What motherboard features are required for this 288-pin ECC RDIMM to function?

The board must provide a DDR5 RDIMM slot, support registered ECC memory, and be validated for 6400 MHz PC5-51200 operation with 2Rx4 modules.

Can this DDR5 stick share a channel with DDR5 RDIMMs of different capacity or rank that I keep from an earlier upgrade?

Mixing capacities or ranks in the same channel is not recommended; the memory controller will train all modules to the lowest common speed and timing, reducing the 6400 MHz benefit.
