4GB DDR3 ECC Registered DIMM

This A-Tech module delivers 4GB of DDR3 1600 (PC3-12800) server memory with ECC and registered buffering. It operates at the standard 1.5V with CL11 latency and uses a 2Rx8 organisation on a 240-pin DIMM. The module is built with major-brand chips and tested for dependable operation in server and workstation platforms.

Suited for registered ECC DDR3 slots only

It fits systems that require registered ECC DDR3 DIMMs and accept a 2Rx8 configuration at 1600MHz. Buyers whose platforms need unbuffered memory or a different voltage cannot use this module. Those requiring larger single-module capacities must choose a different part.

Registered ECC with 2Rx8 organisation

The registered ECC design and dual-rank 2Rx8 layout are the key specifications that determine compatibility. Verify that your motherboard or server supports registered ECC DDR3 and this rank structure before purchasing.

Questions about this item

What motherboard slot does this 240-pin DDR3 RDIMM require?

This module fits a standard 240-pin DDR3 DIMM slot on a server or workstation motherboard that supports registered ECC memory.

Can I mix this CL11 registered ECC stick with older unbuffered non-ECC DDR3 modules?

No, registered ECC RDIMMs cannot be mixed with unbuffered non-ECC UDIMMs; the motherboard must support registered ECC for this module to function.

How do I confirm the module is running at 1600 MHz with ECC active after installation?

Check the BIOS memory information or use a system utility such as CPU-Z to verify the speed shows 1600 MHz and the ECC status reads enabled.
