Server-grade 32 GB DDR4 module

This 32 GB DDR4 DIMM is built for servers that require registered ECC memory. It delivers 2133 MT/s at CL15 with a 1.20 V operating voltage. The module targets administrators who need reliable capacity for virtualisation or database workloads.

Registered ECC with 2Rx4 organisation

The single specification that determines fit is the registered ECC design combined with a 2Rx4 rank layout. Only platforms that explicitly support registered modules and this rank configuration will initialise the memory correctly. Standard desktop or unbuffered server boards will not accept it.

Steady 1.20 V operation under load

The module maintains its rated 1.20 V across the VDD range of 1.14 V to 1.26 V during sustained use. Sixteen internal banks and bank grouping help distribute access patterns evenly, preventing hot-spots during long-running compute jobs. No heat spreader is fitted, so chassis airflow must handle thermal dissipation.

Questions sur cet article

What does the 32 GB capacity mean once this module is installed in a server?

The module provides a single 32 GB DIMM, expanding system memory by that amount and operating at the rated DDR4 2133 speed with ECC and registered signalling.

How does the DDR4 2133 (PC4 17000) interface limit real-world throughput?

The DDR4 2133 standard sets a maximum data rate of 2133 MT/s, so peak bandwidth is capped at the PC4 17000 level regardless of the server’s memory controller.

What physical slot and clearance does the 288-pin registered DIMM require?

It fits a standard 288-pin DDR4 DIMM socket; the module has no heat spreader, so only the bare PCB height needs to clear the server’s DIMM spacing.
