NEMIX RAM 16GB DDR5 4800 ECC RDIMM

This 16GB DDR5 registered DIMM runs at 4800 MT/s with CL40 latency and 1.1V operation. It is built for the SuperMicro IOT SuperServer SYS-221HE series including FTNR, FTNRD and TNR models. The module uses major OEM chips from Samsung, Micron or Hynix and carries ECC with registered buffering for server stability.

Suits SYS-221HE servers needing ECC registered

Administrators upgrading SuperMicro IOT SuperServer SYS-221HE platforms will find the correct pinout, voltage and registration here. Builders requiring unbuffered UDIMMs, non-ECC modules, faster speeds than 4800 MT/s, lower latency than CL40, different capacities or consumer desktop memory should look elsewhere.

288-pin DDR5 RDIMM with 1Rx8 organisation

The single-rank x8 layout fits the 288-pin DDR5 RDIMM slots of the target SuperMicro systems. Verify that your motherboard accepts registered ECC DDR5 at 4800 MT/s with 1.1V before purchase.

Questions about this item

Does the SYS-221HE server need a DDR5-capable motherboard slot to accept this 288-pin RDIMM?

Yes, the module is a DDR5 288-pin registered DIMM and requires a motherboard with DDR5 RDIMM slots; the SuperMicro SYS-221HE-FTNR, SYS-221HE-FTNRD and SYS-221HE-TNR platforms provide those slots.

Can this CL40 1Rx8 ECC registered module share channels with other DDR5 RDIMMs of different rank or capacity?

Mixing ranks or capacities on the same channel is not recommended; for stable operation populate each channel with identical 1Rx8 DDR5 4800 CL40 1.10V registered modules.

How can I confirm the module is running at 4800 MT/s with ECC active after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify the speed shows 4800 MT/s, the part number reads MR38400-618K1 and ECC status reports enabled.
