Server Memory Kit

This OWC kit provides 1TB of DDR4 memory across eight 128GB ECC Load Reduced DIMMs. The modules run at 2933MHz with CL21 latency and 1.2V power draw. They are built specifically for HP Apollo 4200 Gen10 and 6500 Gen10 servers.

Workstation and Server Upgrades

The kit suits administrators expanding capacity in compatible Apollo Gen10 platforms for virtualization or large datasets. It will not work in standard desktop PCs, consumer workstations, or any system that requires unbuffered or standard registered ECC memory. Mixing with other memory types is not supported.

Compatibility Check

Verify that your server is an HP Apollo 4200 Gen10 or 6500 Gen10 before ordering. Confirm the motherboard has eight available 288-pin DDR4 slots and supports Load Reduced ECC modules at 1.2V. The memory is backward compatible with 2133MHz, 2400MHz, and 2666MHz bus speeds.

Highlights

Questions about this item

Will this 288-pin DDR4 ECC LRDIMM kit work in my HP Apollo 4200 Gen10 server?

Yes, the kit is specifically validated for HP Apollo 4200 Gen10 and 6500 Gen10 systems, replacing HP part numbers such as P19047-H21 and P11040-B21.

Can I mix these 2933MHz CL21 LRDIMMs with existing 2666MHz registered ECC DIMMs in the same server?

No, load-reduced ECC memory cannot be mixed with unbuffered or registered ECC modules; all slots must use identical LRDIMM technology.

How do I confirm the kit is running at the correct 2933MHz speed after installation?

Check the BIOS or UEFI memory information screen; it should report DDR4 2933 (PC4-23400) with CL21 timings and 1.2V operation.
