Micron 32GB 3200MHz DDR4 PC4-25600 ECC Registered CL22 288-Pin DIMM 1.2V Single Rank x4 Memory Module – MTA18ASF4G72PZ-3G2E1

Micron 32GB DDR4-3200 ECC RDIMM 1Rx4 — MTA18ASF4G72PZ-3G2E1

The Micron MTA18ASF4G72PZ-3G2E1 is a 32GB DDR4-3200 ECC Registered DIMM (RDIMM) operating at 3200MHz (PC4-25600) with CL22 latency at 1.2V in Single Rank x4 configuration. The E1 suffix identifies a specific production revision. As a 1Rx4 module it offers lower memory bus loading than dual rank variants enabling more DIMMs per channel in some server configurations on Intel Xeon Scalable and AMD EPYC platforms.

Key Features

• Single Rank x4 (1Rx4) — lower bus loading than 2Rx4 enabling more DIMMs per channel
• DDR4-3200 — highest standard DDR4 server speed
• ECC Registered — register buffer for enterprise server reliability
• E1 production revision
• Genuine Micron server memory

Frequently Asked Questions

What is the difference between MTA18ASF4G72PZ-3G2E1 (1Rx4) and MTA36ASF4G72PZ-3G2E7 (2Rx4)?

Both are 32GB DDR4-3200 ECC RDIMMs. MTA18ASF4G72PZ-3G2E1 is Single Rank x4 (1Rx4) with lower bus loading while MTA36ASF4G72PZ-3G2E7 is Dual Rank x4 (2Rx4) with higher effective bandwidth. Choose based on your server”s rank loading requirements and QVL.

What does 1Rx4 mean?

Single Rank x4 — one rank of x4 (4-bit wide) DRAM devices. Single rank modules have lower memory controller loading than dual rank allowing more DIMMs per channel in some server configurations.

What does the E1 suffix mean?

E1 is a production revision identifier for the MTA18ASF4G72PZ-3G2 base part. Electrical specifications are consistent across E-suffix revisions — the suffix tracks manufacturing revision for QVL qualification.

The Micron MTA18ASF4G72PZ-3G2E1 delivers 32GB DDR4-3200 ECC RDIMM in 1Rx4 configuration — the E1 single-rank revision for Intel Xeon Scalable and AMD EPYC DDR4 server platforms requiring lower rank loading at 32GB per slot.
