4GB DDR3 1333MHz ECC RDIMM Server Module

This A-Tech 4GB DDR3 1333MHz ECC RDIMM module uses Micron chips and a registered 2Rx8 layout to deliver error-correcting memory for servers and workstations. It runs at PC3-10600 speed with CL9 latency at 1.50V. The 240-pin DIMM form factor fits standard DDR3 registered slots.

Suited for registered DDR3 platforms needing ECC

This module suits administrators upgrading or repairing systems that require registered ECC DDR3 memory at 1333MHz. It will not work in platforms that only accept unbuffered non-ECC DIMMs or that require a different DDR generation. Builders needing higher capacity per slot should look at larger modules.

Registered ECC with 2Rx8 organisation

The single specification that decides fit is the registered ECC design with 2Rx8 organisation. Only motherboards wired for registered DDR3 ECC at 1333MHz will accept this part; unbuffered or non-ECC boards will not post with it installed.

Questions about this item

Does the 2Rx8 rank layout of this DDR3 module require any specific maintenance or replacement planning?

The 2Rx8 organisation is a physical layout of the memory chips; it does not create a wear item or a scheduled replacement interval.

What limit appears first when this 1.50 V DDR3 1333 MHz RDIMM runs under sustained load?

The registered buffer and ECC logic add a small latency overhead, so the memory controller’s timing budget is typically the first bottleneck under continuous heavy traffic.

How much heat and power does a single 4 GB DDR3 1333 MHz registered ECC DIMM draw when the server runs all day?

At the standard 1.50 V DDR3 voltage a 4 GB RDIMM typically draws only a few watts, producing modest heat that normal server airflow handles without extra cooling.
