  • Validated for HP Apollo 4500 Gen10 and 4510 Gen10

Server-grade capacity

This OWC kit delivers 512GB of DDR4 ECC registered memory across eight 64GB modules. It is built for HP Apollo 4500 Gen10 and 4510 Gen10 servers that require registered DIMMs. Standard desktop systems cannot use this memory. Mixing with unbuffered or load-reduced ECC modules is not supported.

288-pin registered DIMM form factor

Each module uses the 288-pin RDIMM interface and operates at 1.2V without a heat spreader. The registered design adds a buffer that reduces electrical load on the server memory controller. Backward compatibility with 2133MHz, 2400MHz and 2666MHz platforms allows deployment in older slots while running at the lower speed.

JEDEC-standard thermals and power

The modules comply with JEDEC DDR4 specifications and run at the standard 1.2V voltage. No additional cooling hardware is required beyond normal server airflow. Power draw scales with the eight-module population and the configured memory speed.

Questions about this item

Does the DDR4 2933 PC4-23400 interface run at its rated speed or drop to 2666 MT/s on the Apollo 4500 Gen10?

The modules are rated DDR4 2933 PC4-23400 CL21 and are backward compatible with 2666, 2400 and 2133 MT/s; actual speed depends on the server CPU and DIMM population rules.

What physical slot and clearance does the 288-pin 2Rx4 RDIMM need inside the HP Apollo 4510 Gen10?

Each module is a standard 288-pin DDR4 ECC Registered DIMM with no heat spreader, so it fits the regular DIMM slots on the Apollo 4500/4510 Gen10 motherboards.

What is the correct installation order for the eight 64 GB modules to avoid a boot failure?

Populate all eight slots following the HP Apollo 4500/4510 Gen10 memory population guide — typically one DIMM per channel in sequence — and do not mix these Registered DIMMs with Unbuffered or Load-Reduced modules.
