System-specific ECC RDIMM kit

This NEMIX RAM kit delivers 64 GB of DDR4 registered memory in four 16 GB modules. It is built for servers and workstations that require error-correcting code and registered signal integrity. The modules run at 3200 MT/s with a CAS latency of 22 at 1.2 V. They fit 288-pin DDR4 RDIMM slots in compatible ASRock Rack platforms.

Quad-module matched set

The package contains four identical 2Rx8 modules tested together for multi-channel stability. No heat spreaders are included, allowing dense DIMM spacing in 1U and 2U chassis. The kit eliminates the guesswork of mixing single sticks and ensures uniform timing across all populated channels. Each module uses major OEM DRAM from Samsung, Micron or Hynix.

EPYC motherboard validation

Compatibility is validated for the ASRock Rack ROMED8-2T motherboard with AMD EPYC processors. The registered ECC design meets the strict electrical requirements of that platform. Builders targeting other server boards or consumer desktop chipsets should verify qualified vendor lists before purchase.

Preguntas sobre este artículo

Will the 2Rx8 registered modules need any firmware updates or re-seating to maintain stability over time?

No firmware updates are required for the DDR4 3200 modules; the 2Rx8 registered design handles signal integrity at the hardware level. Reseating is only necessary if the system is moved or the chassis is opened for other service.

What limit appears first when the 64 GB kit runs continuously at CL22 1.20 V on an EPYC platform?

The memory controller's maximum supported frequency and rank-per-channel rules are reached before the modules themselves hit a thermal or voltage ceiling.

How much noise and heat do the four bare registered DIMMs produce during all-day operation?

Without heat spreaders the modules run passively; they add no fan noise and only marginally increase case temperature at the rated 1.20 V.
