Server memory upgrade kit

This 256GB kit contains two 128GB DDR4 2933 CL21 ECC LRDIMM modules built for the HP ProLiant XL270d Gen10. It targets administrators who need maximum registered capacity in that specific platform.

256GB load-reduced capacity

The dual-rank 8Rx4 design delivers 256GB across two 288-pin slots at 1.2V. Backward compatibility covers 2133, 2400 and 2666MHz speeds, but the modules will not work in standard desktops or alongside unbuffered or registered ECC memory.

Thermals and power in use

Operating at 1.2V without heat spreaders, the LRDIMMs rely on server chassis airflow for cooling. Load-reduced buffering reduces electrical load on the memory controller, keeping power draw steady during sustained workloads.

Soalan tentang produk ini

Will the 288-pin DDR4 2933 LRDIMM modules run alongside my existing 2666 MHz ECC memory in the HP ProLiant XL270d Gen10?

The kit is backward compatible with 2133, 2400 and 2666 MHz speeds, but LRDIMM modules cannot be mixed with unbuffered or standard registered ECC DIMMs.

How do I confirm the 2 x 128 GB kit is detected at 2933 MT/s with CL21 timing after installation?

Check the system BIOS or iLO interface; it should report 256 GB total, DDR4 2933 (PC4-23400) CL21 1.2 V ECC Load Reduced operation.

Does the OWC 256 GB upgrade kit include only the two 128 GB LRDIMM modules, or are any tools or cables also supplied?

The package contains the two 128 GB DDR4 2933 CL21 8Rx4 288-pin 1.2 V ECC Load Reduced DIMMs; no tools, cables or additional hardware are included.
