16 GB DDR3-1866 ECC Registered DIMM

This 16 GB DDR3-1866 module targets servers and workstations that require error-correcting, registered memory. It suits administrators upgrading compatible platforms where data integrity and stability take priority over consumer-grade speed.

DDR3-1866 interface limits bandwidth to PC3-14900

The DDR3-1866 standard caps peak transfer rates at PC3-14900, so throughput cannot exceed what the bus allows. Registered buffering adds a clock cycle of latency, which benefits signal integrity on heavily populated channels but reduces raw responsiveness compared with unbuffered alternatives.

240-pin keyed installation prevents misalignment

The 240-pin DDR3 key ensures the module seats in only one orientation, making physical insertion straightforward on supported boards. Failures usually arise when the platform does not support registered ECC DIMMs or when mixed ranks prevent the system from posting.

Questions about this item

Should I pick the 16 GB module or a different capacity?

This listing is for a single 16 GB registered DIMM; choose it when your server needs exactly 16 GB per slot.

What does the 1866 MT/s rating deliver in a live server?

It provides DDR3-1866 transfer rates with CL13 latency, giving 14 900 MB/s peak bandwidth per module.

How does the 240-pin DDR3 registered interface limit performance?

The registered 240-pin DDR3 bus tops out at the DDR3-1866 data rate and CL13 timing specified for this module.
