Server DDR5-4800 ECC RDIMM

This 32 GB registered DDR5 module operates at 4800 MT/s with a CAS latency of CL40 and a standard voltage of 1.10 V. It uses Samsung chipset components in a 1Rx4 (EC4) organisation and provides on-die ECC for error detection and correction. The 288-pin DIMM form factor is designed for server and workstation platforms that require registered memory with ECC support.

Suited for ECC-registered platforms

The module is intended for systems that accept registered DDR5 DIMMs with ECC functionality and a 1.10 V supply. Builders whose motherboards require unbuffered non-ECC memory or a different pin count should select an alternative module. Compatibility must be verified against the system documentation before purchase.

Sustained workload behaviour

Registered buffering and on-die ECC help maintain data integrity during continuous operation in multi-socket server environments. The DDR5 4800 interface delivers consistent bandwidth for memory-intensive tasks such as virtualization, database serving and scientific computing. Thermal characteristics follow the DDR5 standard voltage specification of 1.10 V under prolonged load.

Questions about this item

Does my server need a DDR5 RDIMM slot to accept this 288-pin module?

Yes, the module is a DDR5 RDIMM with 288 pins and requires a matching DDR5 RDIMM slot on the motherboard.

Can I keep my existing DDR5 RDIMM modules and add this 32GB stick?

You can add it alongside other DDR5 RDIMMs, but the system will run all modules at the speed and timings of the slowest stick installed.

How do I confirm the module is running at 4800 MT/s with ECC active after installation?

Check the memory speed and ECC status in your system BIOS or UEFI; it should report 4800 MT/s and show ECC enabled for the new module.
