8GB DDR3 1866 ECC Registered DIMM

This 8GB DDR3 module runs at 1866 MHz with CL13 latency and 1.5V operation. It uses a single-rank x4 layout and registered ECC buffering for data integrity. The 240-pin form factor fits server and workstation platforms that require registered memory.

Suited for DDR3 servers

This module is not compatible with desktop or laptop computers that use unbuffered DIMMs. Systems that cannot accept registered modules or that require a different voltage will not work with this part.

Registered ECC with 1Rx4 organisation

The registered buffer and ECC function are mandatory for the target platform; unbuffered or non-ECC modules will not operate in these systems. Verify that your motherboard specifies registered ECC DDR3 support before purchasing.

Questions about this item

What does DDR3 1866 actually deliver once the module is installed in a server?

The module runs at 1866 MT/s with CL13 latency, giving your server or workstation a measurable increase in memory bandwidth for faster load times and smoother multitasking under heavy workloads.

How does the PC3-14900R rating limit real-world throughput?

PC3-14900R certifies a peak transfer rate of 14900 MB/s on a registered DDR3 channel; the registered buffer adds one cycle of command delay but ensures signal integrity on multi-DIMM server boards.

What physical slot and clearance does the 240-pin RDIMM need?

It fits a standard 240-pin DDR3 DIMM socket keyed for registered modules; the single-rank x4 layout keeps the module height within normal server DIMM clearance limits.
