512GB DDR4 ECC RDIMM kit

This OWC kit supplies 512 GB across eight 64 GB DDR4 2933 CL21 registered ECC modules. It is built for HP Apollo 4200 Gen10 and 6500 Gen10 servers that require 288-pin 1.2 V RDIMMs. The 2Rx4 organisation and PC4-23400 rating match the platform specifications exactly.

Suited to Apollo 4200 and 6500 Gen10 upgrades

IT teams refreshing those specific HP Apollo servers can install this kit directly. It will not work in standard desktops, workstations that take unbuffered ECC, or systems needing load-reduced DIMMs. Buyers with other server platforms should verify their qualified-vendor lists before purchasing.

Eight modules fill all channels on supported

The 512 GB total provides substantial headroom for virtualisation, large databases and high-thread-count workloads on the compatible Gen10 systems. Capacity runs out when workloads exceed the physical memory ceiling of the platform or when the application set demands more than the installed 512 GB.

Questions about this item

What server models must I already own for this 512GB DDR4 2933 CL21 ECC Registered RDIMM kit to work?

This kit is validated for HP Apollo 4200 Gen10 and HP Apollo 6500 Gen10 servers; it replaces HP part numbers including 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.

How will these 2Rx4 288-pin 1.2V modules behave if I keep older DDR4 DIMMs running at 2133, 2400 or 2666 MT/s in the same server?

The modules are backward compatible with 2133, 2400 and 2666 MT/s speeds; the system will run all installed DIMMs at the lowest common speed, and registered ECC DIMMs must not be mixed with unbuffered or load-reduced memory.

How can I confirm the 8 x 64GB CL21 kit is operating correctly after installation?

Check the server BIOS or management console to verify all 512GB are detected at DDR4 2933 (PC4-23400) with ECC Registered status active and no memory errors reported during POST.
