32GB DDR4 3200 ECC Registered Module

This 32GB DDR4 3200 module delivers ECC registered performance for server environments. The 288-pin DIMM operates at 1.20V with CL22 latency and 2Rx4 organisation. Integrated ECC parity helps prevent data errors and increases overall system reliability.

Suited for ECC Registered Server Builds

This module suits administrators upgrading or repairing DDR4 servers that require registered ECC memory. Builders needing non-ECC unbuffered DIMMs for consumer platforms should look at something else. Systems that only support single-rank population rules cannot use this dual-rank part.

Registered ECC With 2Rx4 Organisation

The registered buffer and ECC parity are the decisive specifications for compatibility. The dual-rank 2Rx4 layout must match the server memory population rules. Verify the platform requires registered ECC DDR4 before purchase.

Questions about this item

Does the Crucial MTA36ASF4G72PZ-3G2R1R package include a heat spreader or any cables?

The module is a bare 288-pin DIMM without a heat spreader; no cables or accessories are included.

When should I choose the 32 GB 2Rx4 CL22 registered ECC version over a lower-capacity or unbuffered alternative?

Select this 32 GB 2Rx4 RDIMM when your server requires registered ECC memory at DDR4 3200 and you need maximum capacity per slot.

What does the DDR4 3200 (PC4 25600) rating deliver in a compatible server?

It provides a 3200 MT/s data rate with CL22 timing at 1.20 V, enabling registered ECC operation for error-corrected throughput.
