16 GB DDR3 ECC Registered module

This 16 GB DDR3 1866 ECC Registered DIMM targets server administrators upgrading compatible enterprise platforms. The 240-pin form factor fits standard DDR3 registered slots. Registered buffering and ECC protect data integrity in multi-socket systems. It is not for desktop builders whose motherboards require unbuffered non-ECC memory.

DDR3 1866 registered speed ceiling

The DDR3 1866 (PC3 14900) interface caps bandwidth at the JEDEC standard for this generation. Registered modules add one clock cycle of latency versus unbuffered equivalents. Dual-rank 2Rx4 organisation helps density but limits maximum DIMMs per channel on many chipsets. Buyers needing higher throughput must migrate to a newer platform.

240-pin registered build implications

Gold-plated edge contacts resist oxidation in long-term rack deployments. The registered buffer chip increases module height slightly, so verify heatsink clearance in dense 1U chassis. ECC and registration require motherboard BIOS support; consumer boards will not post with this module. No heatspreader is included, relying on chassis airflow.

Questions about this item

Should I choose the 16 GB module or the 64 GB kit for my server?

The 16 GB module suits incremental upgrades; the 64 GB kit (2×32 GB LRDIMM) fills two slots for maximum density.

What does DDR3 1866 (PC3 14900) deliver in a running system?

It provides 1866 MT/s data rate and 14 900 MB/s peak bandwidth per module.

How does the 240-pin DDR3 interface limit this memory?

The 240-pin DDR3 slot caps speed at 1866 MT/s and requires registered ECC support.
