OWC 512GB (8x64GB) DDR4 2933 ECC Registered RDIMM Memory Upgrade Kit

SKU CH-5MVT-AHSW0

Eight 64 GB DDR4 2933 ECC registered RDIMMs totalling 512 GB for HP ProLiant XL270d Gen10 servers

  • Capacity512GB (8 x 64GB)
  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.2V
  • ECCYes

Capacity 512GB (8 x 64GB)

  • ECC registered design protects data integrity in critical workloads
  • 512 GB total capacity across eight 64 GB modules
  • DDR4 2933 CL21 timing matches server platform requirements
  • 2 V operation reduces power draw per DIMM
  • Backward compatible with 2133, 2400 and 2666 MHz systems

Capacity & purpose

This kit delivers 512GB of DDR4 ECC registered memory in eight 64GB modules for the HP ProLiant XL270d Gen10. It targets server and workstation workloads that demand error correction and registered buffering.

Compatibility check

Verify that your system uses 288-pin DDR4 RDIMM slots and supports registered ECC memory at 1.2V. The kit replaces HP part numbers including P19045-K21, P00930-H21 and P14636-001. It will not work with unbuffered or load-reduced DIMMs.

Thermals & power

Modules run at 1.2V without heat spreaders, relying on chassis airflow for cooling. Rated speeds include 2933MHz with backward compatibility to 2133MHz, 2400MHz and 2666MHz. Noise and power draw follow standard DDR4 RDIMM behaviour in typical server environments.

Highlights

  • ECC registered design protects data integrity in critical workloads
  • 512 GB total capacity across eight 64 GB modules
  • DDR4 2933 CL21 timing matches server platform requirements
  • 2 V operation reduces power draw per DIMM

Questions about this item

Does the 512GB kit include eight 64GB modules or must I buy them separately?

The kit contains eight 64GB DDR4 2933 ECC Registered RDIMM modules, giving 512GB total with nothing extra to purchase.

Why choose the 512GB (8x64GB) CL21 2Rx4 kit over a smaller capacity for the HP ProLiant XL270d Gen10?

It fills eight slots with 64GB 2Rx4 registered DIMMs at the server's supported 2933MHz speed, maximising capacity while matching the required ECC registered specification.

Will the 2933MHz rating run at that speed or drop to 2666MHz in my XL270d Gen10?

The modules are rated for 2933MHz and are backward compatible with 2133MHz, 2400MHz and 2666MHz; the server's memory controller will select the highest supported speed.
