Server-grade ECC RDIMM

This OWC module is a 64GB DDR4 2933 PC4-23400 CL21 2Rx4 288-pin 1.2V ECC Registered RDIMM. It is built for workstations and servers that require registered error-correcting memory. The single stick adds substantial capacity to compatible HP ProLiant Gen10 platforms.

Replaces HP part numbers

The upgrade replaces HP part numbers P19045-K21, P19045-B21, P00930-H21, P14636-001, P00930-K21, P06192-001, P03053-CA1, P00930-B21, P03053-1A1, P03053-0A1, P14492-B21 and P19045-H21. It also runs at 2133, 2400 and 2666 MHz when the system bus requires a lower speed. The jump is worth it when expanding virtualization density or database buffers on supported Gen10 hardware.

Suits ProLiant Gen10 owners

This memory suits administrators extending BL460c, DL325, DL360, DL380 or DL385 Gen10 servers with validated ECC registered modules. It will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced DIMMs. Buyers needing unbuffered ECC or consumer DDR4 should look at something else.

Questions about this item

Does the 288-pin DDR4 ECC RDIMM fit the DIMM slots on an HP ProLiant DL380 Gen10?

Yes, the module is a 288-pin DDR4 ECC Registered DIMM designed for the listed ProLiant servers including the DL380 Gen10.

What is the correct way to seat this 64GB 2Rx4 module so the ECC registered buffer initialises properly?

Align the notch with the slot key, press firmly until both retention clips click, then verify the server POST reports 2933 MHz CL21 at 1.2 V.

When should this 1.2 V ECC registered DIMM be replaced if correctable error counts start rising in the iLO logs?

Replace the module once the platform firmware logs show a sustained increase in correctable ECC errors, indicating cell wear on the 2Rx4 DRAM.
