32GB Registered ECC DDR4 Module

This 32GB DDR4-2666 registered ECC module targets server administrators maintaining HPE infrastructure. The 2Rx4 organisation and 1.20V operation match OEM specifications for compatible platforms.

DDR4-2666 Registered ECC Constraints

Registered ECC DDR4-2666 modules require a server chipset and BIOS that support registered memory and error correction. Mixing registered and unbuffered DIMMs in the same system prevents boot. The 288-pin DDR4 form factor fits only DDR4 slots.

HPE 881900?B21 Compatibility

This module is validated as 100 percent compatible with the HPE 881900?B21 part number. Buyers needing a different part number or non-HPE qualification cannot use this module.

Questions about this item

Should I choose the 32 GB 2Rx4 registered ECC module or a different capacity for my HPE server?

This module provides 32 GB in a single 2Rx4 registered ECC DIMM, matching the 881900?B21 part number for direct replacement in compatible HPE systems.

What does the DDR4-2666 speed rating deliver once the module is installed?

The module operates at 2666 MT/s with 1.20 V voltage, providing the rated data rate for workloads that require registered ECC stability.

How does the 288-pin DDR4 interface and PC4-21300 rating limit real-world throughput?

The 288-pin DDR4 form factor and PC4-21300 specification define the electrical and mechanical interface, capping the module to the standard DDR4-2666 signalling rate.
