  • DDR5 4800 speed rated at PC5-38400 for server workloads
  • ECC registered RDIMM design protects data integrity
  • 10 V operation reduces power draw per module
  • Validated for SuperMicro X13SEI-F and X13SEI-TF motherboards

Purpose-built server memory kit

This 64GB kit contains four 16GB DDR5 modules tuned to 4800MHz with CL40 latency. ECC and registered operation target administrators upgrading SuperMicro X13SEI-F or X13SEI-TF platforms. The 1.1V modules suit workloads that demand data integrity over raw bandwidth.

Registered design for dense configurations

Each 288-pin RDIMM uses a 1Rx8 layout with major OEM chips from Samsung Micron or Hynix. Registration buffers the command bus so the motherboard can populate all slots without signal degradation. No heat spreader is fitted so clearance inside 1U chassis remains uncomplicated.

Validated kit removes guesswork

The four modules ship pre-matched under part number MR38400-618K4 so installers avoid mixed-rank or mixed-die issues. Stress testing under load is performed before dispatch to reduce first-boot failures in mission-critical deployments.

Questions about this item

What DDR5 standard and speed does this 4800 CL40 kit conform to?

The kit conforms to the DDR5 4800 (PC5-38400) standard with a CAS latency of CL40.

What physical slot and module type are required for these 288-pin RDIMMs?

The modules are 288-pin DDR5 RDIMMs and require server motherboard slots that accept registered ECC memory.

What is the correct installation sequence for this 4-module kit on the target board?

Install one module per channel following the motherboard manual's population order; a common error is filling slots sequentially instead of across channels.
