384GB DDR5-6400 ECC RDIMM kit for Supermicro

This 384GB kit contains six 64GB DDR5-6400 Registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H13SVW-N memory controller expects. It is intended for administrators who need maximum supported capacity in that specific platform.

6400 MT/s with CL52 latency and 1.10V operation

The modules run at 6400 MT/s (PC5-51200) with CL52 timings at 1.10V. Registered architecture allows all six slots to be populated at full speed, while on-die ECC corrects single-bit errors before they reach the OS. Headroom ends at the motherboard's qualified voltage and population limits.

2Rx4 Registered ECC DDR5 RDIMM form factor

Each module is a 288-pin 2Rx4 Registered ECC DDR5 RDIMM. This form factor is mandatory for the H13SVW-N; UDIMM or SODIMM variants will not fit or function. Verify your board's population rules and maximum supported capacity before ordering.

Questions about this item

Will the 288-pin DDR5-6400 RDIMMs work alongside any existing DDR5 modules already installed in my Supermicro H13SVW-N?

Mixing DIMMs with different ranks, speeds or latencies can prevent the memory controller from training at 6400 MT/s. For guaranteed operation, populate all six slots with this matched 2Rx4 CL52 kit and remove any other modules.

How can I confirm the kit is running at the rated 6400 MT/s and CL52 after installation?

Enter the system BIOS or UEFI and verify the memory frequency shows 6400 MT/s (PC5-51200) with CAS latency 52. The registered ECC design also logs corrected errors in the system event log, confirming ECC is active.

Does the package include only the six 64 GB RDIMMs, or are any extra parts such as heat spreaders or cables supplied?

The box contains exactly the six 288-pin DDR5-6400 2Rx4 registered ECC RDIMMs that make up the 384 GB kit. No heat spreaders, cables or additional accessories are included.
