4GB DDR3 1600 ECC UDIMM Server Module

This 4 GB DDR3 1600 (PC3-12800) ECC UDIMM runs at 1.50 V with CL11 latency and a 2Rx8 rank layout. It uses a 240-pin DIMM form factor and Major Brand chips for dependable server and workstation upgrades.

Suited for systems requiring DDR3 ECC unbuffered

Administrators replacing a failed stick or adding capacity to a compatible DDR3 platform will find this module fits the spec. Buyers whose hardware only accepts registered ECC DIMMs or non-ECC consumer memory cannot use this part.

ECC UDIMM with 2Rx8 organisation

The module provides error-correcting unbuffered operation in a dual-rank 2Rx8 configuration at DDR3 1600 speed. Verify that your motherboard supports DDR3 ECC UDIMM at this voltage and rank before ordering.

Questions about this item

Does this module come as a single 4GB stick or do I need to buy multiple units?

The package contains one 4GB DDR3 1600 ECC UDIMM module; additional sticks must be purchased separately if your system requires more capacity.

Should I choose this CL11 1.5V 2Rx8 version or look for a different latency or rank?

This CL11 1.5V 2Rx8 module matches the Kingston KVR16E11/4 specification; select it when your server or workstation calls for DDR3 1600 ECC UDIMM with those exact timings and rank.

What does the PC3-12800 rating mean for actual server performance?

PC3-12800 identifies the module as DDR3 1600 with a standard 1.5V operating voltage and CL11 latency, delivering the bandwidth and error correction your compatible platform expects.
