SKU CH-2SXT-88K9H MPN MTA9ASF2G72PZ-3G2R

16 GB DDR4-3200 ECC registered server memory module with CL22 latency at 1.20 V

  • 16 GB single-rank module expands server capacity
  • DDR4-3200 speed delivers 25600 MT/s data rate
  • ECC registered design corrects errors for reliability
  • CL22 latency at 1.20 V balances timing and power
  • Micron-built DRAM ensures component-level quality control

16 GB DDR4-3200 ECC registered module

This single 16 GB DDR4-3200 module delivers error-correcting, registered memory for servers and workstations that require data integrity. It suits IT administrators and system builders who need to populate registered DIMM slots with validated Micron components.

1.20 V operation and CL22 latency

The module runs at the standard 1.20 V DDR4 voltage with a CAS latency of CL22 at 3200 MHz. Registered signal processing reduces electrical load on the memory controller, helping to maintain stable thermals and predictable power draw in multi-DIMM configurations.

Single-rank layout and ECC protection

A single-rank design simplifies rank interleaving for the memory controller, while on-die ECC corrects single-bit errors before they reach the CPU. Together they improve uptime for virtualization hosts, database servers and other workloads that cannot tolerate silent data corruption.

Questions about this item

How do I install this 16 GB DDR4-3200 ECC registered module, and what step is often missed?

Align the notch on the 288-pin DIMM with the slot key, press firmly until both retention clips click, then verify in BIOS that the module runs at 3200 MHz with CL22 timings; the step often missed is enabling the correct memory profile so the rated speed is actually used.

What maintenance or replacement will this 1.20 V registered ECC DIMM need over time?

No scheduled maintenance is required; keep server air filters clean so the module stays within its thermal limits, and replace only if memory diagnostics report uncorrectable ECC errors or the system fails to POST with the DIMM installed.

What limit appears first when this single-rank CL22 module runs under sustained load?

The primary limit is the CL22 latency at 3200 MHz, which determines maximum sustained bandwidth; thermal throttling may occur if chassis airflow is insufficient for continuous 1.20 V operation.
