32GB DDR4 3200MHz ECC UDIMM Server Memory

This 32GB DDR4 3200MHz ECC UDIMM module is built for servers and workstations that require error-correcting memory. It operates at PC4-25600 speed with a CL22 latency and 1.20V voltage. The 2Rx8 rank configuration suits systems designed for high-capacity unbuffered DIMMs.

288-pin DIMM with Micron chipset compatibility

The module uses a standard 288-pin DDR4 DIMM form factor and is a compatible replacement for Micron MTA18ASF4G72AZ-3G2 and related part numbers. Unbuffered design means direct connection to the memory controller without a register. Verify your platform supports ECC UDIMMs before installation.

Low-voltage operation at 1.20V for efficient

Running at the DDR4 standard 1.20V keeps power draw and heat output modest under normal workloads. ECC functionality adds a small overhead but maintains stability without active cooling requirements. The module relies on system airflow for thermal management.

Questions about this item

What DDR4 standard does the PC4-25600 rating cap the module at in practice?

The PC4-25600 rating corresponds to DDR4 3200 MHz, which is the maximum data rate this 32GB module is specified to run at.

Will this 288-pin DDR4 UDIMM fit a standard server DIMM slot?

Yes, it uses the 288-pin DDR4 DIMM form factor and 1.20V voltage required by standard unbuffered server memory slots.

Do I need to configure anything in BIOS for the ECC and 2Rx8 organisation to work correctly?

Most server platforms detect ECC and the dual-rank 2Rx8 layout automatically; just ensure the memory mode is not set to non-ECC in BIOS.
