Server-grade ECC RDIMM for Apollo 4200

This OWC module is a 64GB DDR4 3200 ECC Registered DIMM built specifically for the HP Apollo 4200 Gen10 Plus. It targets administrators who need to expand memory in that server platform without mixing memory types. The part replaces several HP part numbers including P43170-B21 and P06035-B21. It is not for standard desktop computers or systems that require unbuffered or load-reduced DIMMs.

Registered ECC with 2Rx4 organisation

The decisive specification is the registered ECC design with 2Rx4 rank configuration at CL22 latency. This memory will not work in platforms that accept only unbuffered or load-reduced modules. The 288-pin DDR4 form factor and 1.2V operation match the Apollo 4200 Gen10 Plus requirements exactly. Mixing this module with other memory types will prevent the system from booting.

Straightforward DIMM installation

Installation follows standard server DIMM procedure: power down, open the chassis, align the notch and press until the latches engage. The module has no heat spreader, so it fits tight DIMM slots without clearance issues. The common mistake is mixing this registered ECC stick with unbuffered or load-reduced memory, which causes boot failure. OWC tests every module in-house to reduce the chance of a defective stick.

Questions about this item

What does the 3200 MT/s rating mean once the module is installed in my Apollo 4200 Gen10 Plus?

The module is rated for DDR4 3200 (PC4-25600) operation; the server's memory controller will set the final speed based on the processor and how many DIMMs are populated per channel.

How does the 288-pin RDIMM interface affect what I can install alongside it?

This is a registered ECC DIMM; it cannot be mixed with unbuffered or load-reduced modules and will only work in platforms that support registered memory.

What physical clearance does the 64 GB stick need inside the HP Apollo 4200 Gen10 Plus?

It is a standard-height 288-pin DDR4 RDIMM with no heat spreader, so it fits the regular DIMM slots of the Apollo 4200 Gen10 Plus without extra clearance.
