Server Memory Module

This A-Tech module provides 4GB of DDR3 1866 ECC unbuffered memory for compatible servers and workstations. It uses a 240-pin DIMM form factor with a single rank x8 organisation and operates at 1.5V. The CL13 latency and PC3-14900E rating suit systems designed for this specification.

Target Systems and Limits

This module suits administrators upgrading DDR3 servers or workstations that require ECC unbuffered DIMMs. It will not work in desktop or laptop computers, nor in platforms that need registered or load-reduced memory. Buyers needing larger capacities or higher speeds must verify their platform supports such configurations.

Deciding Specification

The DDR3 1866 ECC unbuffered 240-pin interface is the single specification that determines compatibility. Only systems explicitly qualified for DDR3 ECC UDIMM at this speed and voltage will accept the module. Confirm the memory type, ECC support, and pin count in your hardware documentation before ordering.

Questions about this item

Should I choose a single-rank x8 module or a dual-rank option for my server?

This module is a single-rank x8 (1Rx8) design, which places less electrical load on the memory controller and often allows higher total capacities per channel in DDR3 servers.

What real-world throughput can I expect from the DDR3 1866 rating once installed?

At 1866 MT/s the module runs at the PC3-14900 data rate, so peak bandwidth scales directly with that clock speed in your server's memory subsystem.

Does the 240-pin ECC UDIMM interface limit the maximum speed I can run?

The 240-pin unbuffered ECC DIMM form factor is specified for DDR3 1866 at 1.5 V with CL13 latency, and the memory controller will not exceed that standard rate.
