  • Total capacity128 GB (4 × 32 GB)
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • 128 GB total capacity from four 32 GB modules
  • DDR5 4800 speed with CL40 latency for server workloads
  • ECC registered RDIMM protects data integrity under load
  • 1 V operation reduces power draw in dense systems
  • Validated for Supermicro SYS-211E and X13SEM platforms

Server ECC RDIMM Kit

This 128GB kit contains four 32GB DDR5 4800 CL40 registered ECC modules built for Supermicro servers. It targets IT teams upgrading X13SEM-F or X13SEM-TF platforms that require registered memory with error correction.

Registered ECC Requirement

The motherboard must accept 288-pin DDR5 RDIMM modules with on-die ECC and a registered buffer; unbuffered or non-ECC DIMMs will not function in these Supermicro systems.

128GB Four-Channel Capacity

Four single-rank 32GB modules populate four channels for maximum bandwidth at 1.10V. Workloads exceeding 128GB or needing higher frequencies than 4800MT/s will require a different memory configuration.

Questions about this item

Will the DDR5 4800 speed run at full rate on my Supermicro X13SEM-F server?

The modules are rated for DDR5 4800 and the Supermicro X13SEM-F platform supports that data rate natively, so the kit will operate at its advertised speed without manual tuning.

Does the 288-pin RDIMM form factor and registered buffer match the X13SEM-TF memory slots?

Yes, the 288-pin DDR5 RDIMM design with registered buffering is exactly what the X13SEM-TF and related SuperServer boards require for ECC server memory.

How much clearance do the four 32 GB sticks need above the motherboard?

The modules have no heat spreader, keeping them at the standard low-profile DDR5 RDIMM height so they fit under typical server CPU coolers and chassis lids.
