  • 288-pin DIMM form factor fits server boards

Product identity

This is a 4GB DDR4 2400MHz ECC UDIMM built as a compatible replacement for Micron MTA9ASF51272AZ-2G3 and MTA9ASF51272AZ-2G3B1 modules. It targets server and workstation systems that require unbuffered error-correcting memory at standard 1.2V operation.

Compatibility checks

Verify that your platform accepts DDR4 ECC UDIMM modules with a 288-pin interface and supports 2400MHz speed at CL17 latency. Confirm the motherboard or system documentation lists unbuffered ECC DIMMs and 1Rx8 organisation as supported configurations before ordering.

Build integration

The module fits a standard DDR4 DIMM slot and draws 1.2V, leaving headroom within typical server memory power budgets. Its single-rank 1Rx8 layout helps maintain signal integrity on populated channels, while ECC capability protects data integrity for critical workloads.

Questions sur cet article

Does the 4GB DDR4 2400MHz ECC UDIMM arrive as a single 288-pin module or do I need to order multiple sticks?

The product is a single 4GB module in a 288-pin DDR4 DIMM form factor; no extra sticks or accessories are included.

The listing mentions Micron MTA9ASF51272AZ-2G3 and MTA9ASF51272AZ-2G3B1 — which version should I pick?

Both part numbers refer to the same 4GB DDR4 2400MHz ECC UDIMM specification; this module is a compatible replacement for either.

What does the PC4-19200 rating tell me about actual throughput in my server?

PC4-19200 is the module's rated peak bandwidth at 2400MHz with CL17 timing and ECC enabled.
