  • 2Rx4 dual-rank organisation increases density per slot
  • Backward compatible with 2133, 2400 and 2666 MHz systems

Server-grade ECC RDIMM

This 64GB DDR4 module runs at 2933MHz with CL21 latency and 1.2V operation. It is built for Supermicro motherboards X11SPA-TF, X11SPD-F, X11SPG-TF, X11SPH-nCTF and X11SPH-nCTPF. The registered design with ECC suits workstation and server workloads that demand data integrity.

Straightforward slot installation

Align the 288-pin notch and press firmly until the retention clips engage. No heat spreader is fitted, so clearance is rarely an issue. The module will not work in standard desktop boards and must not be mixed with unbuffered DIMMs. Systems running at 2133MHz, 2400MHz or 2666MHz will downclock automatically.

Registered ECC requirement

The single deciding specification is the registered ECC RDIMM form factor. Only platforms that explicitly support registered error-correcting memory can use this kit. Buyers needing standard unbuffered desktop RAM or non-ECC modules must choose a different product.

Preguntas sobre este artículo

How can I confirm the 64GB DDR4 2933MHz CL21 ECC RDIMM is running at the correct speed after installation?

Enter the system BIOS or UEFI and verify the memory frequency reads 2933MHz (PC4-23400) with CL21 timings and 1.2V voltage.

What is included in the box and do I need to purchase any additional components for installation?

The box contains the single 64GB 288-pin ECC Registered RDIMM module; no extra cables, brackets or cooling parts are required.

Which capacity or version should I choose for a Supermicro X11SPA-TF motherboard?

This 64GB 2Rx4 module replaces Supermicro part numbers MEMDR464LCL01ER29, MEMDR464LHL02ER29, MEMDR464LSL01ER29 and MEM-DR464MC-ER29.
