8GB DDR3 1866 ECC RDIMM

This module provides 8GB of registered ECC memory for servers and workstations that require DDR3 1866 operation. It is intended for administrators upgrading or repairing compatible Micron-based platforms.

DDR3 1866 interface limits

The DDR3 1866 standard caps transfer rates at 1866 MT/s and operates at 1.50V. Registered signalling adds a clock cycle of latency, so maximum throughput is lower than unbuffered DDR3 at the same frequency.

8GB capacity and headroom

An 8GB stick handles typical virtualisation workloads and moderate database caches. Systems needing larger per-socket memory footprints or higher memory bandwidth will exceed what a single 8GB module can deliver.

Questions about this item

Should I choose the 8GB DDR3 1866 ECC RDIMM or a different capacity for my server?

This module provides 8GB per stick at 1866MHz with CL13 latency. Match the total capacity to your motherboard's maximum supported memory and available DIMM slots.

What does the PC3-14900 rating mean for real-world server performance?

PC3-14900 indicates a peak transfer rate of 14,900 MB/s at 1866MHz. The CL13 timing and registered design help maintain stability under sustained multi-threaded workloads.

How does the DDR3 240-pin registered ECC interface limit speed and capacity in practice?

The DDR3 240-pin RDIMM interface caps at 1866MHz and 1.5V here. The registered buffer allows higher per-slot capacities than unbuffered DIMMs while ECC corrects single-bit errors.
