256GB DDR5-6400 ECC RDIMM kit for Supermicro

This 256GB kit contains eight 32GB DDR5 6400 RDIMMs built to the PC5-51200 standard with CL52 latency and 1.10V operation. Registered ECC architecture and 2Rx8 organisation provide the signal integrity and error correction required by the Supermicro H13DSG-OM motherboard. It is intended for server administrators who need maximum supported capacity in every DIMM slot.

Verify your motherboard manual before ordering

The H13DSG-OM has specific population rules for registered DIMMs; the manual lists approved capacities per channel and the required slot-filling sequence. Confirm that your BIOS revision supports 256GB total and 2Rx8 modules at 6400 MT/s. This kit uses 288-pin RDIMMs only and will not fit UDIMM or SODIMM sockets.

Thermals noise and power in normal server use

Registered ECC modules run at 1.1V without heat spreaders, relying on chassis airflow for cooling. In typical fully populated operation they add minimal power draw and produce no audible noise of their own. Ensure your server fans deliver sufficient airflow across all eight slots to maintain rated temperatures.

Questions about this item

What comes in the kit and is anything else needed to install it?

The kit includes eight 32 GB DDR5 6400 RDIMM modules for a total of 256 GB. No extra parts are required; the modules plug directly into the Supermicro H13DSG-OM motherboard.

Why choose the 8 × 32 GB kit instead of a different capacity?

The 8 × 32 GB configuration fills all eight DIMM slots on the H13DSG-OM with 2Rx8 registered ECC modules, delivering the maximum supported 256 GB at the rated DDR5 6400 speed.

What does the DDR5 6400 CL52 rating mean for real-world server performance?

DDR5 6400 (PC5 51200) transfers data at 6400 MT/s with a CAS latency of 52 cycles, providing high throughput and error correction for stable operation under full load.
