Four green DDR5 RDIMM modules in anti-static tray

NEMIX RAM

NEMIX RAM CSE-GS7A-2000B 256GB (4x64GB) DDR5 4800MHz ECC RDIMM memory upgrade

SKU CH-8BEB-ZH33V MPN CSE-GS7A-2000B

Adds 256GB of DDR5 4800MHz ECC registered memory in four 64GB modules for Supermicro SuperWorkstation SYS-551A-T systems

  • Capacity256GB (4 x 64GB)
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 256 GB total capacity from four 64 GB modules
  • DDR5 4800 MT/s speed rated at PC5-38400 bandwidth
  • ECC registered RDIMM design protects data integrity

256GB DDR5-4800 ECC RDIMM kit for Supermicro

This 256GB memory kit contains four 64GB DDR5 4800MHz registered DIMMs built for the Supermicro SuperWorkstation SYS-551A-T and compatible X13SWA-TF motherboards. It targets IT professionals and system integrators who need validated ECC registered memory for mission-critical server and workstation workloads. The modules operate at 1.10V with CL40 latency.

Four-module kit enables full 256GB capacity

The package delivers four matched 64GB modules (2Rx4 organisation) so a four-slot motherboard can reach the full 256GB capacity in a single installation. Buyers who need more than four DIMM slots or a different total capacity cannot use this specific kit and must select another part number.

DDR5 4800MHz ECC registered RDIMM

The decisive specification is the DDR5 4800MHz ECC registered RDIMM format with 2Rx4 rank architecture and 1.10V operation. Systems that require unbuffered UDIMMs, a different speed grade, non-ECC memory, or a different rank configuration will not accept these modules.

Points forts

  • 256 GB total capacity from four 64 GB modules
  • DDR5 4800 MT/s speed rated at PC5-38400 bandwidth
  • ECC registered RDIMM design protects data integrity
  • 1 V operating voltage reduces power draw
  • Validated for Supermicro SuperWorkstation SYS-551A-T compatibility

Questions sur cet article

Do the 64 GB DDR5 modules need any firmware updates or periodic re-seating to keep ECC working?

No firmware updates or re-seating are required; the registered DDR5 modules run at 1.10 V with on-die ECC that operates continuously once installed.

What thermal limit appears first when the 256 GB kit runs at 4800 MT/s under constant load?

The DDR5 RDIMMs have no heat spreader, so the DRAM junction temperature reaches its throttling point before the 1.10 V power envelope becomes a constraint.

How much extra power draw and fan noise should I expect from four 64 GB sticks at 4800 MHz all day?

Each module draws roughly 1.1 V at standard DDR5 current, so the kit adds only modest wattage; registered buffering keeps signal integrity high without increasing acoustic output.
