32GB DDR4 2400 Registered DIMM

This HPE 805351-B21 module provides 32GB of DDR4 2400 memory with CL17 timing and 1.20V operation. The 288-pin registered design includes a 2Rx4 rank configuration for server platforms. It is built for enterprise workloads that require registered memory with error correction support. ||

Target servers needing registered ECC memory

This suits administrators upgrading or repairing HPE ProLiant and compatible servers that require registered DDR4 modules. It is not for desktop PCs or laptops that use unbuffered consumer memory. Buyers who need higher frequencies or different capacities should look at other specifications. ||

Registered 2Rx4 rank at 2400 MT/s

The registered signal buffering and 2Rx4 organisation determine whether this DIMM matches the motherboard memory controller requirements. Verify that the platform supports registered DDR4 2400 with this rank configuration before purchase.

Questions about this item

What does the 32 GB capacity mean for a live server workload?

The module provides 32 GB of addressable memory for the operating system and applications when installed in a compatible DDR4 slot.

What does the DDR4 2400 (PC4 19200) rating cap in practice?

The memory runs at up to 2400 MT/s with CL17 timing at 1.20 V, limited by the platform memory controller and BIOS settings.

What does the 288-pin registered 2Rx4 design need to fit?

A 288-pin DDR4 DIMM slot that supports registered modules; the 2Rx4 organisation requires a memory controller that can address quad-rank x4 devices.
