16 GB DDR4 ECC RDIMM for servers

This 16 GB DDR4 2133 MHz registered DIMM carries ECC protection and a 2Rx4 organisation. It is built for server platforms that require registered memory and will not function in standard desktop or laptop systems.

Replaces non-ECC or unregistered modules

The jump is worthwhile when the platform demands error-correcting registered memory for data integrity. Systems that accept only unbuffered DIMMs or lack ECC support cannot use this module at all.

Installs in a 288-pin DDR4 slot at 1.2 V

Ensure the motherboard explicitly supports RDIMM population rules and the correct rank configuration. The most common issue is attempting installation in consumer boards that only accept unbuffered memory.

Questions about this item

What motherboard slot does this 288-pin DDR4 RDIMM require?

It fits a standard 288-pin DDR4 DIMM socket on a server motherboard that supports registered ECC memory.

Which orientation step is most often missed when seating the module?

Align the off-centre notch on the module with the key in the slot, then press straight down until both side clips click locked.

When should this 1.2 V dual-rank module be replaced?

Replace it if system logs report correctable ECC errors that become uncorrectable, or if a full memory test shows persistent failures.
