Server Memory Upgrade

This 32 GB DDR4 module is built for Supermicro platforms that require registered ECC memory. It suits administrators expanding capacity in compatible servers or workstations.

Build Integration

The load-reduced 4Rx4 organisation places less electrical load on the memory controller, freeing DIMM slots for additional modules. A 288-pin LRDIMM form factor fits the corresponding DDR4 server sockets on qualified motherboards.

Thermals and Power

Standard 1.20 V operation keeps power draw in line with DDR4 server specifications. ECC error correction maintains data integrity under sustained workloads without adding active cooling requirements.

Questions about this item

How does the 4Rx4 quad-rank organisation affect memory-channel limits on my server?

Each module presents four ranks to the memory controller, so a single DIMM consumes four rank slots on its channel; check your platform's maximum ranks per channel before populating multiple slots.

What power draw and thermal load should I expect from a 1.2 V DDR4 LRDIMM running continuously at 2133 MHz?

At the standard 1.2 V DDR4 voltage the module draws typical server-memory power; the load-reduced buffer reduces electrical loading on the bus, helping keep thermals manageable during all-day operation.

Which motherboard features are required for this 288-pin LRDIMM to function?

The board must provide DDR4 LRDIMM support with ECC enabled and a 288-pin slot wired for load-reduced signalling; registered or unbuffered-only platforms will not accept this module.
