System-specific DDR5 RDIMM for Supermicro

This 64GB registered ECC module runs at 6400MHz with a CL52 latency and operates at 1.10V. It is built as a single 2Rx4 rank on a 288-pin form factor without a heat spreader. The part is validated for the Supermicro MP SuperServer SYS-242B-NR platform.

Verify DDR5 RDIMM slot availability and ECC support

Confirm the server has free 288-pin DDR5 RDIMM slots and that the motherboard firmware accepts registered ECC memory at this speed and voltage. Check the maximum supported capacity per channel and the total system limit before adding this 64GB module. Ensure the existing configuration can accommodate a 2Rx4 rank organisation.

Replaces lower-capacity

The upgrade is worthwhile when the workload demands more than the currently installed memory can provide or when modules rated below 6400MHz are limiting throughput. It suits environments that require registered ECC reliability at the specified voltage and latency. Systems already populated with identical 6400MHz CL52 RDIMMs will not gain from this change.

Questions about this item

Does the module arrive as a single 64 GB stick or do I need to order multiple pieces to reach that capacity?

The package contains one 64 GB DDR5 6400 MHz 288-pin ECC RDIMM; no additional modules are required to reach the stated capacity.

Why is this part listed as 2Rx4 CL52 instead of a lower-latency option?

The 2Rx4 organisation and CL52 timing are the validated configuration for the Supermicro SYS-242B-NR platform, providing registered ECC operation at 1.10 V.

Will the advertised 6400 MT/s speed run at that rate once installed in the SYS-242B-NR?

Yes, the module is qualified for 6400 MHz PC5-51200 operation on the Supermicro SYS-242B-NR, delivering the rated throughput with registered ECC stability.
