Server-ready DDR4 ECC RDIMM

This 8 GB registered DIMM runs at DDR4 3200 (PC4-25600) with CL22 latency and 1.20 V operation. It targets administrators who need error-correcting memory for stable server or workstation workloads. The single-rank 1Rx8 organisation keeps electrical loading light on populated channels.

Major-brand chips on a 288-pin registered module

Registered buffering reduces signal load on the memory controller, helping reliability in multi-DIMM configurations. ECC circuitry detects and corrects single-bit errors before they affect data integrity. Standard DDR4 voltage simplifies power delivery in compatible platforms.

Replaces Micron MTA9ASF1G72PZ-3G2 in qualified

The module is validated as a direct equivalent for that Micron part number, so it fits existing qualified server configurations without requalification. The upgrade is worthwhile when expanding capacity in slots that already support DDR4 3200 registered ECC. It will not work in platforms that require unbuffered or non-ECC memory.

Questions about this item

What DDR4 speed and PC4 rating does this module run at?

This module runs at DDR4 3200 MHz with a PC4-25600 data rate, matching the server platform's rated transfer speed.

What physical slot and pin count does this RDIMM require?

It uses the standard 288-pin DDR4 DIMM form factor, so it fits any server or workstation board with DDR4 RDIMM slots.

How is this ECC registered DIMM installed, and what step is often missed?

Align the module's notch with the slot key, press firmly until both retention clips click, then verify in BIOS that ECC and registered mode are enabled.
