A-Tech 8GB DDR3 1866 ECC RDIMM 2Rx8 CL13 1.5V Server Memory

8GB DDR3 1866 ECC RDIMM for Servers

This 8GB registered DIMM runs at DDR3 1866 speed with CL13 latency and 1.5V operation. It is built for server and workstation systems that require error-correcting memory. The 2Rx8 organisation and 240-pin form factor match the Micron MT18JDF1G72PDZ-1G9 and related part numbers. Buyers needing unbuffered UDIMM modules or higher-density single-rank sticks cannot use this part.

Registered ECC design with major-brand chips

The registered buffer reduces electrical load on the memory controller, allowing larger memory populations in multi-socket platforms. On-board ECC detects and corrects single-bit errors to protect data integrity in critical workloads. Major-brand DRAM chips are used throughout, and every module undergoes quality-assurance testing before shipment. Systems that do not support registered or ECC memory will not accept this module.

DDR3 1866 (PC3-14900) speed grade

The module operates at 1866 MT/s with a CAS latency of 13 cycles at the standard 1.5V DDR3 voltage. This speed rating determines whether the memory matches the platform's qualified vendor list and maximum supported frequency. Installing modules rated for a different speed or voltage can prevent the system from posting or force it to run at a lower rate.
