NEMIX RAM

NEMIX RAM 256GB (2x128GB) DDR5 4800 CL40 4Rx4 ECC RDIMM memory upgrade

SKU CH-Y429-BVZ75

A 256 GB registered DDR5 server kit with ECC, CL40 timing and 1.1 V operation for Supermicro X13SEW platforms

  • Capacity256GB (2 x 128GB)
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • Massive 256GB capacity handles heavy workloads
  • DDR5 4800 speed delivers high bandwidth throughput
  • ECC registered design protects data integrity
  • 4Rx4 architecture maximises density per module
  • 1V operation reduces server power draw

Purpose-Built Server Memory

This 256 GB kit supplies two 128 GB DDR5 4800 CL40 4Rx4 ECC RDIMM modules designed for SuperMicro X13SEW-TF and X13SEW-F motherboards. Registered buffering and on-die ECC protect data integrity in multi-socket workloads. The 1.10 V operating voltage matches the platform specification.

Ideal for Capacity-Critical Servers

Suits administrators expanding memory in the named SuperMicro platforms where maximum registered DIMM density is required. Builders needing unbuffered UDIMMs, lower capacities, or consumer desktop compatibility should look at other product lines.

Decisive Specification: 4Rx4 Registered ECC

The quad-rank 4Rx4 organisation with registered control and ECC is the single attribute that determines whether this kit will post and run stably in the target SuperMicro server boards.

Points forts

  • Massive 256GB capacity handles heavy workloads
  • DDR5 4800 speed delivers high bandwidth throughput
  • ECC registered design protects data integrity
  • 4Rx4 architecture maximises density per module
  • 1V operation reduces server power draw

Questions sur cet article

How does the 4800 MT/s speed translate to real-world throughput in a Supermicro X13SEW server?

The DDR5 4800 rating delivers up to 38400 MB/s of peak bandwidth per module, so the dual-channel pair can move large datasets at near that ceiling when the platform runs at the rated frequency.

What does the PC5-38400 designation limit in practice?

PC5-38400 caps the module at 4800 MT/s with CL40 latency at 1.1 V; the registered buffer adds one cycle but keeps signal integrity across all 288 pins in multi-DIMM configurations.

Will these 288-pin RDIMMs fit the X13SEW-TF memory slots without clearance issues?

Yes, the 288-pin DDR5 RDIMM form factor matches the X13SEW-TF and X13SEW-F slots exactly, and the modules have no heat spreader to interfere with adjacent DIMMs or CPU coolers.
