4GB DDR3 1600 ECC UDIMM for Servers

This A-Tech module provides 4GB of DDR3 1600MHz ECC unbuffered memory for server and workstation systems. It operates at 1.5V with CL11 latency and uses a 2Rx8 rank configuration on a 240-pin DIMM form factor. The module is a compatible replacement for the Micron MT18JSF51272AZ-1G6M1 part number.

Suits ECC UDIMM slots.

This memory suits administrators upgrading or repairing servers that accept unbuffered ECC DDR3 DIMMs. Builders whose platforms require registered or load-reduced DIMMs should look at different modules, as this stick will not function in those slots. Systems limited to non-ECC memory also cannot use this module.

240-pin DDR3 DIMM form factor decides fit

The single specification that decides compatibility is the 240-pin DDR3 DIMM form factor combined with unbuffered ECC operation. Verify your motherboard documentation for DDR3 1600MHz PC3-12800 UDIMM support and 2Rx8 rank acceptance before purchasing.

Questions sur cet article

Does the DDR3 1600 PC3-12800 interface limit the module to CL11 timing at 1.50V?

Yes, this ECC UDIMM is specified at CL11 CAS latency and operates at the standard DDR3 voltage of 1.50V.

Will the 240-pin DIMM fit a standard server UDIMM slot keyed for 262-pin modules?

The module uses a 240-pin DIMM form factor; 262-pin is a different keying used for SO-DIMMs, so verify your board accepts 240-pin UDIMMs before ordering.

Is there a specific orientation step for installing this 2Rx8 ECC UDIMM that installers often miss?

Align the notch on the 240-pin edge connector with the slot key, press straight down until both retention clips click — forcing it backwards bends pins and prevents the ECC module from seating.
