SKU CH-ZQYE-EY64N

A 128GB DDR4 2933 ECC load-reduced DIMM for Supermicro X11SPA-TF servers

  • Capacity128GB
  • Type288-Pin DDR4 ECC LRDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.2V
  • ECCYes

Capacity 128GB

Doorgestreepte varianten bestaan wel, maar zijn hier niet op voorraad.

  • 128 GB single module expands server memory capacity
  • ECC load-reduced design protects data integrity in critical workloads
  • DDR4 2933 MHz CL21 delivers high-speed registered performance
  • 2 V operation reduces power draw for dense configurations
  • Validated for Supermicro X11SPA-TF with backward speed compatibility

Server-grade memory upgrade

This 128GB DDR4 2933 module is built for the Supermicro X11SPA-TF motherboard. It targets administrators who need to expand capacity in a server, workstation or NAS system that requires load-reduced ECC memory.

Load-reduced ECC design

The module uses a 288-pin LRDIMM form factor with 4Rx4 organisation and operates at 1.2V. It cannot be mixed with unbuffered or registered ECC DIMMs, so the platform must support load-reduced memory exclusively.

128GB single-module capacity

One stick delivers the full 128GB at DDR4 2933 CL21, with backward compatibility at 2133, 2400 and 2666 speeds. Buyers who need smaller increments or non-ECC memory should look elsewhere.

Vragen over dit artikel

What speed does the DDR4 2933 PC4-23400 interface actually run at on the Supermicro X11SPA-TF?

The module is rated for 2933 MT/s and will operate at that speed if the platform supports it; otherwise it will down-clock to 2666, 2400 or 2133 MT/s automatically.

Does the 288-pin LRDIMM fit the X11SPA-TF DIMM slots without a heat spreader?

Yes, the 288-pin form factor matches the board's DDR4 slots and the module has no heat spreader, so it clears standard server heatsinks and chassis lids.

How is the single 128 GB 4Rx4 LRDIMM installed, and what mixing rule catches people out?

Insert the module into an empty DDR4 slot until the ejector tabs click; do not mix this load-reduced ECC DIMM with unbuffered or registered ECC memory.
