Certified Server Memory Upgrade

This A-Tech module provides 32GB of DDR4 3200 ECC registered memory built on Micron chips and validated for Supermicro systems. The dual-rank 2Rx8 organisation and CL22 latency suit workloads that demand data integrity and sustained throughput. It installs in a standard 288-pin RDIMM slot and operates at the DDR4 standard voltage of 1.2V.

Compatibility Verification Required

Confirm that your motherboard or server platform supports DDR4 RDIMM modules with ECC and registered buffering before purchase. The platform must accept 32GB single-module capacity and a 3200 MT/s data rate at CL22 timing. Systems limited to unbuffered UDIMMs or lower maximum densities will not recognise this module.

Build Quality and Daily Implications

Micron chipset construction and Supermicro certification indicate adherence to server-grade qualification standards. The registered design adds a clock cycle of buffering that stabilises electrical loading on dense memory buses. ECC circuitry corrects single-bit errors transparently, protecting data integrity during continuous operation in multi-module configurations.

Questions about this item

Does the 288-pin RDIMM module ship alone or with any extra brackets or cables?

The module is a single 32GB stick; no brackets, cables or additional hardware are included.

Should I pick the 3200MHz CL22 2Rx8 version or a different speed/rank for my Supermicro board?

Choose this exact 3200MHz CL22 2Rx8 RDIMM when your board's qualified-vendor list calls for MEM-DR432L-CL05-ER32 or MTA18ASF4G72PDZ-3G2E1.

Will the rated PC4-25600 bandwidth actually appear in a live server?

The module runs at 3200MHz CL22 1.20V; real-world throughput depends on your CPU memory controller and channel population.
