HP Compatible 64GB DDR4 RDIMM

This 64GB DDR4-3200 registered DIMM is built for HP server platforms that require ECC protection and registered signalling. It targets administrators expanding memory in compatible ProLiant or Apollo systems where data integrity and high density are priorities. The module delivers 64GB in a single slot using a 2Rx4 organisation.

Registered ECC limits on consumer boards

Registered signalling and ECC require a server-class memory controller; standard desktop chipsets cannot initialise this module. Mixing registered and unbuffered DIMMs is not supported, so the full capacity must be populated with matching registered parts. The PC4-25600 rating indicates a 3200 MT/s data rate at 1.20V.

Major-brand chips and lifetime warranty

Major-brand chipset components are used throughout, giving consistent electrical margins across the 2Rx4 array. The 288-pin RDIMM form factor fits standard DDR4 server slots and locks with the familiar ejection levers. A lifetime warranty from the supplier backs the HP-compatible build.

Questions about this item

Should I pick the 64GB 2Rx4 module or a different rank for my server?

The 64GB 2Rx4 configuration balances density and rank count, letting you populate more DIMM slots before hitting the platform’s rank-per-channel limit.

What does the 3200Mhz rating deliver once the module is installed in a live system?

At 3200 MT/s the module runs at the standard DDR4-3200 data rate, providing 25600 MB/s of peak bandwidth per stick when the memory controller is set to its maximum supported speed.

How does the PC4-25600 designation relate to the DDR4 interface and what does it cap in practice?

PC4-25600 is the JEDEC module name for DDR4-3200; it caps the theoretical peak transfer rate at 25600 MB/s, which the memory controller cannot exceed regardless of other settings.
