Server DDR5 RDIMM 32 GB 5600

This 32 GB registered DDR5 module runs at 5600 MT/s with CL46 latency. ECC and dual-rank 2Rx8 organisation protect data integrity in multi-socket servers. The 288-pin RDIMM form factor fits standard DDR5 server slots and operates at 1.10 V with 12 V external supply.

For ECC registered DDR5 platforms

Designed for servers and workstations that require registered ECC memory. Systems that accept only unbuffered UDIMMs or that lack DDR5 RDIMM support cannot use this module. Buyers needing non-ECC or consumer SO-DIMM form factors should choose a different product.

Registered ECC with 2Rx8 organisation

The module provides error-correcting code and registered buffering in a dual-rank 2Rx8 layout. This combination decides compatibility with qualified server motherboards and determines whether the memory meets mission-critical reliability requirements.

Questions about this item

Does my server motherboard need 288-pin DDR5 RDIMM slots to use this 32 GB module?

Yes, the module is a 288-pin DDR5 RDIMM and requires a server or workstation board with matching DDR5 RDIMM slots.

Will this 5600 MHz ECC registered DIMM run at its rated speed on a platform that only supports DDR5 4800?

The DIMM will down-clock to the highest speed the platform allows, so on a DDR5 4800 system it will operate at 4800 MHz with corresponding timings.

How can I confirm the module is running at 5600 MHz with CL46 timings after installation?

Check the memory speed and latency reported in the BIOS/UEFI or use a tool such as CPU-Z or dmidecode to verify 5600 MT/s and 46-45-45 timings.
