32GB DDR4 3200 ECC RDIMM

This 32GB DDR4 3200 ECC RDIMM module delivers registered, error-correcting memory for server and workstation platforms. It operates at PC4-25600 speed with CL22 latency and a standard 1.20V voltage. The dual-rank 2Rx4 organisation suits systems that require high-density registered DIMMs.

Thermals and power draw

Registered DDR4 modules at 1.20V draw modest power and run cool inside typical server chassis airflow. The 2Rx4 layout spreads load across ranks, helping maintain stable temperatures during sustained workloads. No active cooling is required beyond standard system ventilation.

Build and day-to-day fit

The 288-pin DIMM uses major-brand chipsets and undergoes quality assurance testing for dependable operation. As a compatible replacement for Hynix HMAG84EXNRA199N, it fits slots keyed for DDR4 RDIMM. Buyers needing unbuffered UDIMM or higher-capacity LRDIMM modules should verify platform requirements before ordering.

Questions about this item

How do I install this 288-pin DDR4 RDIMM and what step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both latches click, then verify in BIOS that the 3200 MHz speed and ECC are active — many forget to enable ECC in firmware.

What maintenance or replacement will this 32 GB ECC RDIMM need over time?

No scheduled maintenance is required; the module either passes POST or it fails, in which case the entire 32 GB stick is replaced as a single unit.

What limit appears first when this CL22 1.20 V RDIMM runs sustained workloads?

The registered buffer adds one cycle of latency, so memory-controller throughput saturates before the DRAM chips reach thermal limits under continuous load.
