Micron 32GB DDR4-3200 ECC RDIMM 1Rx4 — MTA18ASF4G72PZ-3G2B1R (Renesas Register)

The Micron MTA18ASF4G72PZ-3G2B1R 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 R suffix denotes the Renesas register component variant of the B1 production revision for Intel Xeon Scalable and AMD EPYC DDR4 server platforms.

Key Features

  • Renesas register component (R suffix)
  • Single Rank x4 (1Rx4) — lower bus loading enabling more DIMMs per channel
  • B1 production revision
  • DDR4-3200 — highest standard DDR4 server speed
  • ECC Registered — register buffer for enterprise server reliability

  • Verify server QVL for B1R Renesas variant qualification
  • Not compatible with DDR5 platforms or UDIMM-only systems

Frequently Asked Questions

What does the R suffix mean in MTA18ASF4G72PZ-3G2B1R?
The R suffix indicates a Renesas register component variant. Electrical specifications are identical to MTA18ASF4G72PZ-3G2B1 — the difference is the register chip vendor.
What is the difference between MTA18ASF4G72PZ-3G2B1R and MTA18ASF4G72PZ-3G2B1?
MTA18ASF4G72PZ-3G2B1R uses a Renesas register component while MTA18ASF4G72PZ-3G2B1 is the standard variant. Electrical specifications are identical — check your server QVL for the qualified variant.
Can I mix B1R and B1 modules in the same server?
Mixing register component variants is generally not recommended. Verify your server vendor QVL to confirm which variants are qualified for your platform.

The Micron MTA18ASF4G72PZ-3G2B1R delivers 32GB DDR4-3200 ECC RDIMM in 1Rx4 configuration with Renesas register component — the B1R variant for Intel Xeon Scalable and AMD EPYC DDR4 server platforms.
