Server-grade ECC RDIMM for HP ProLiant

This is a single 64GB DDR4 2933 MHz CL21 registered ECC RDIMM built for the HP ProLiant XL270d Gen10. It runs at 1.2 V and uses a 2Rx4 rank configuration without a heat spreader. The module is designed for server and workstation platforms that require registered memory with error correction.

Registered ECC prevents desktop use

The defining specification is the registered ECC design, which makes this module incompatible with standard desktop motherboards and prevents mixing with unbuffered or load-reduced ECC DIMMs. Systems must support 288-pin DDR4 registered memory at 2933 MHz to accept this upgrade.

Suits HP ProLiant XL270d Gen10 owners

Buyers maintaining or expanding an HP ProLiant XL270d Gen10 will find this a direct replacement for the listed HP part numbers. It is not for desktop PC builders, laptop upgraders, or any system that requires unbuffered non-ECC memory.

Questions about this item

Will a single 64 GB DDR4 2933 CL21 RDIMM run at its rated speed in my HP ProLiant XL270d Gen10?

Yes, the module is validated for the XL270d Gen10 and will operate at DDR4 2933 CL21 when the platform supports that speed.

What does the PC4-23400 rating mean for real-world bandwidth on this registered ECC module?

PC4-23400 is the JEDEC designation for DDR4 2933; the memory controller and channel configuration determine the usable throughput.

Does the 288-pin registered form factor fit directly into the XL270d Gen10 DIMM slots without an adapter?

Yes, the 288-pin RDIMM matches the server's registered DIMM slots and requires no adapter.
