Supermicro H11DSi-NT EPYC memory upgrade

This 64GB DDR4 3200 registered ECC RDIMM is built for the Supermicro H11DSi-NT motherboard with AMD EPYC processors. It targets administrators who need validated, single-module capacity expansion for mission-critical server workloads.

Single-module 64GB kit simplifies population rules

The package delivers one 64GB stick at CL22 and 1.20V, removing the guesswork of matching multiple DIMMs and leaving remaining slots free for future growth. No heat spreader is included, so airflow clearance follows the board's native layout.

64GB per slot handles large databases

At 3200 MT/s the module feeds multi-socket EPYC platforms with ample bandwidth for in-memory analytics and dense VM hosting. Systems that require more than one module per channel or non-registered memory will not accept this DIMM.

Questions about this item

Will the ECC RDIMM modules need any firmware updates or scheduled replacement?

The modules are built with major-brand DRAM and rigorously stress-tested, so no firmware updates or scheduled replacements are required.

What limits sustained throughput on this 3200 CL22 2Rx4 kit?

The CL22 latency at 3200 MT/s and the 1.2 V DDR4 JEDEC ceiling cap continuous bandwidth before any thermal throttle appears.

How much heat and power does a single 64 GB stick draw under 24/7 load?

At 1.20 V the stick stays within standard DDR4 RDIMM power limits and runs without a heat spreader, so airflow from the server chassis keeps it cool.
