32GB DDR4 2933MHz ECC RDIMM

This A-Tech module is a 32GB DDR4 2933MHz ECC registered DIMM built for server and workstation systems. It uses major-brand chips and runs at the standard 1.20V DDR4 voltage. The single 288-pin module targets administrators upgrading compatible Samsung M393A4K40CB2-CVF or M393A4K40DB2-CVF configurations.

Registered ECC with 2Rx4 organisation

The registered ECC design with 2Rx4 rank organisation is the specification that decides fit. Your system must accept registered ECC DDR4 DIMMs with this exact rank layout; unbuffered or non-ECC slots will not work. Verify the motherboard or server manual lists RDIMM support before ordering.

32GB capacity for virtualisation and databases

A single 32GB stick comfortably handles moderate virtualisation hosts, database buffers and multi-user workloads. Headroom disappears when the memory controller reaches its maximum supported capacity or when the application working set exceeds the installed total, requiring additional modules or higher-density parts.

Questions about this item

What does the 2933 MHz rating mean once the module is installed in a server?

The module operates at DDR4 2933 (PC4-23400) with a CAS latency of 21, providing the rated transfer speed when the platform runs memory at that frequency.

How does the ECC RDIMM interface affect what the system can use?

As a registered DIMM with ECC, it presents a controlled electrical load to the memory controller and corrects single-bit errors, which is required for the server platforms that support this module type.

What physical slot and clearance does this 32 GB stick need?

It uses a standard 288-pin DDR4 DIMM form factor, so it fits any DDR4 RDIMM slot with sufficient height clearance for a 32 GB registered module.
