32GB DDR4 3200 ECC RDIMM

This 32GB DDR4 3200 ECC registered DIMM uses Micron chips and carries Supermicro certification. It targets server and workstation builds that require error-correcting memory for data integrity. The module runs at 1.20V with CL22 latency and a dual-rank 2Rx8 organisation.

Sustained workload behaviour

Registered buffering and ECC correction keep data paths stable during continuous multi-threaded tasks such as virtualisation, database serving or scientific compute. Dual-rank density allows higher capacity per channel without increasing electrical load on the memory controller.

Upgrade path and fit

This module replaces lower-capacity or non-ECC DDR4 RDIMMs in qualified Supermicro platforms. The jump is worthwhile when workloads exceed current memory headroom or when silent data corruption risk must be reduced. Verify the system qualified-vendor list before purchase.

Questions about this item

Does the 1.2 V operating voltage keep the module cool when the server runs continuously?

The module operates at 1.2 V, the standard DDR4 voltage, which limits heat output during sustained workloads.

Must the motherboard support registered ECC RDIMMs and the 288-pin DDR4 form factor for this stick to function?

Yes, the system needs a DDR4 RDIMM slot that accepts 288-pin registered ECC modules; unbuffered or non-ECC slots will not work.

Will the CL22 latency at 3200 MT/s cause timing mismatches if mixed with slower DDR4 DIMMs?

Mixing speeds forces all DIMMs to run at the lowest common speed and loosest timings, so this CL22 3200 module will down-clock to match slower sticks.
