Kit composition and target systems

This kit supplies 512GB of DDR4 ECC LRDIMM memory as four 128GB modules. It is built for the HP Apollo 4200 Gen10 and 6500 Gen10 server platforms that require load-reduced registered DIMMs.

Interface limits and mixing rules

The modules run at 2933MHz with a CAS latency of 21 and operate at 1.2V. Load-reduced ECC memory cannot be mixed with unbuffered or standard registered ECC DIMMs in the same system.

Pre-order checks

Verify that the server model is an Apollo 4200 Gen10 or 6500 Gen10 and that all memory slots are populated with matching load-reduced modules. Confirm the existing firmware supports 128GB LRDIMM capacity per slot before installation.

Questions about this item

Should I buy the 512GB kit or look for a smaller capacity for my Apollo 4200 Gen10?

The kit contains four 128GB modules totalling 512GB; choose it when your workload needs that much ECC LRDIMM capacity in a four-slot configuration.

What does the 2933MHz rating actually deliver inside an Apollo 6500 Gen10?

The modules run at DDR4 2933 with CL21 latency and will downclock to 2666, 2400 or 2133 if the system requires a lower speed.

Is the 288-pin LRDIMM interface compatible with standard registered DIMM slots?

No — this is ECC Load-Reduced memory and cannot be mixed with unbuffered or registered DIMMs; it only works in platforms that support LRDIMM.
