Server-grade ECC RDIMM kit

This 128GB kit contains two 64GB DDR4 3200 CL22 ECC Registered RDIMMs built for the HP Apollo 4200 Gen10 Plus. It targets administrators who need registered, error-correcting memory to keep a production server stable under sustained workloads.

Simple DIMM installation

Each 288-pin module seats in the standard DDR4 slots of the Apollo 4200 Gen10 Plus without tools or firmware changes. The registered design will not work in desktop boards, and mixing these sticks with unbuffered or load-reduced DIMMs prevents the system from posting.

128GB registered capacity

The kit delivers 128GB of ECC Registered DDR4 at 3200 MT/s, the single specification that determines whether this upgrade matches the Apollo 4200 Gen10 Plus memory subsystem. Buyers needing unbuffered ECC or consumer DDR4 must select a different part.

Questions about this item

How can I verify the 128GB kit is running at 3200 MT/s and CL22 after installation?

Enter the system BIOS or use a hardware-info utility such as CPU-Z on Windows or dmidecode on Linux; both modules should report DDR4-3200, PC4-25600, CAS 22, 1.2 V and registered ECC operation.

What ships in the box and is anything else required to install the 2Rx4 RDIMMs in an HP Apollo 4200 Gen10 Plus?

The package contains two 64 GB 288-pin DDR4 ECC registered DIMMs (part number 3R2D42R4128P); no additional cables, brackets or cooling parts are needed for the supported server.

Why choose this 128 GB (2×64 GB) CL22 kit over a lower-capacity or different-speed option?

This kit matches the Apollo 4200 Gen10 Plus qualified speed of 3200 MT/s, provides registered ECC with 2Rx4 organisation, and replaces HP part numbers P43170-B21, P06035-B21, P07650-B21 and P25205-B21 for full 128 GB capacity.
