Server memory module

This A-Tech module provides 16GB of DDR3 registered ECC memory for server and workstation systems. It operates at 1333MHz with PC3-10600 bandwidth and a CAS latency of CL9. The 4Rx4 rank configuration and 1.50V voltage match standard DDR3 registered DIMM specifications.

Registered ECC requirement

This module suits administrators upgrading compatible servers that require registered ECC DDR3 memory in a 240-pin form factor. Systems that accept only unbuffered non-ECC UDIMMs or demand a different voltage, speed, or rank layout cannot use this part.

4Rx4 rank constraint

The single most decisive specification is the 4Rx4 registered ECC organisation; the motherboard and memory controller must explicitly support this rank and width combination for the module to function correctly.

Questions about this item

What type of motherboard slot is required for the 240-pin DDR3 DIMM?

The module uses a standard 240-pin DDR3 DIMM form factor and must be installed in a DDR3 DIMM slot that supports registered ECC memory.

Can the 4Rx4 registered module be mixed with 2Rx4 or 1Rx4 DIMMs in the same server?

Mixing different rank configurations such as 4Rx4 with 2Rx4 or 1Rx4 is generally not recommended and may prevent the system from posting or cause instability.

How can I confirm the 16GB module is detected at 1333MHz with ECC active?

Enter the system BIOS or UEFI and verify the memory information shows 16GB, 1333MHz speed, and ECC status as enabled or active.
