Purpose-built server kit

This OWC kit delivers 256GB of DDR4 memory in two 128GB modules for the HP Apollo 4200 Gen10 Plus. It targets administrators who need to expand capacity in that specific server platform. The modules are not compatible with standard desktop computers or consumer motherboards.

Load-reduced ECC requirement

Each module is a 288-pin LRDIMM running at DDR4 3200 with CL22 latency and 1.2V operation. The 4Rx4 organisation and load-reduced buffering are mandatory for the Apollo 4200 Gen10 Plus memory subsystem. Mixing with unbuffered or registered ECC DIMMs is not supported.

Slot-ready upgrade path

The kit plugs directly into the server's DDR4 slots and operates at 3200, 2933, 2666, 2400 or 2133 MHz depending on the system configuration. No heat spreaders are fitted, so airflow follows the chassis design. The two-module layout leaves remaining slots free for further expansion.

Questions about this item

What does the 3200 MHz rating mean once the modules are installed in an HP Apollo 4200 Gen10 Plus?

The kit runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.2 V, and will downclock automatically to 2933, 2666, 2400 or 2133 MHz if the platform requires it.

How does the load-reduced ECC interface affect usable capacity and speed in this server?

Load-reduced DIMMs buffer the data lines so the memory controller sees only one electrical load per rank, allowing 4Rx4 128 GB modules to operate at the rated 3200 MHz without signal degradation.

What physical slot and clearance requirements must the HP Apollo 4200 Gen10 Plus meet for these 288-pin LRDIMMs?

Each module uses a standard 288-pin DDR4 DIMM slot; the kit contains two 128 GB sticks with no heat spreader, so they fit in the server's regular memory bays without extra height clearance.
