Crucial MTA9ADF1G72AZ-3G2E1R 8GB DDR4 3200MHz ECC Unbuffered 1Rx8 CL22 1.2V server RAM

8 GB DDR4 ECC Unbuffered for Workstations

This 8 GB DDR4 module runs at 3200 MHz with CL22 latency and 1.2 V operation. It targets cost-sensitive workstations and entry-level servers that require error-correcting memory. The single-rank 1Rx8 layout keeps the design simple for mainstream platforms. No heat spreader is fitted.

Suited for ECC UDIMM slots only.

Buyers whose motherboards accept unbuffered ECC UDIMMs can use this module for office workloads, media creation or light hosting. Systems that require registered or load-reduced DIMMs cannot use it. Builds needing more than 8 GB per slot should choose higher-capacity sticks. Platforms limited to non-ECC memory are also incompatible.

Single-rank 1Rx8 organisation decides fit

The module is organised as 1Rx8, which determines how the memory controller addresses each rank. Verify that your board supports single-rank unbuffered ECC UDIMMs before purchase. Mixing ranks can prevent boot or reduce stability. This specification is the primary compatibility filter.
