  • ECC load-reduced design protects data integrity in servers
  • 2933 MHz DDR4 speed supports high-throughput workloads
  • 256 GB kit (2 × 128 GB) maximises memory capacity
  • JEDEC and RoHS compliant for warranty-safe upgrades
  • Backward compatible with 2133, 2400 and 2666 MHz systems

Server-grade memory kit

This 256GB kit delivers two 128GB DDR4 2933 CL21 ECC Load Reduced LRDIMM modules designed for the Supermicro X11SPA-TF motherboard. It targets administrators expanding capacity in compatible servers, workstations or NAS systems that require registered load-reduced memory.

Verify platform compatibility

The kit uses 288-pin LRDIMM form factor with 4Rx4 organisation and 1.2V operation, so the host must support DDR4 ECC load-reduced memory at PC4-23400 speed. It cannot be mixed with unbuffered or standard registered DIMMs, and desktop platforms will not accept these modules.

JEDEC-compliant build quality

Modules ship without heat spreaders and meet JEDEC and RoHS standards for warranty-safe upgrades. Backward compatibility with 2133, 2400 and 2666MHz buses allows deployment in mixed-speed environments while the 288-pin connector ensures secure seating in qualified server slots.

Vragen over dit artikel

Does the kit include anything besides the two 128GB LRDIMM modules, or do I need to buy heatsinks or cables separately?

The upgrade kit contains only the two 128GB DDR4 2933 CL21 4Rx4 ECC Load Reduced 288-pin DIMMs. No heat spreaders, cables or additional hardware are included or required.

My Supermicro X11SPA-TF has eight DIMM slots — should I choose this 256GB 2x128GB kit or a different capacity to fill the board?

This 256GB kit provides two 128GB LRDIMMs. You can populate the remaining six slots with identical 128GB modules later to reach the board's maximum supported capacity.

The module is rated PC4-23400 2933MHz CL21 — what speed will it actually run at in my X11SPA-TF?

The memory will operate at up to 2933MHz CL21. The board also supports backward compatibility at 2666MHz, 2400MHz and 2133MHz if the CPU or BIOS limits the frequency.
