ASRock TRX50 WS Compatible DDR5 RDIMM

This 64GB registered DDR5 module is built for the ASRock TRX50 WS workstation motherboard. It targets IT professionals and system builders who need validated ECC memory for mission-critical server and workstation deployments. The single-stick design simplifies capacity scaling in qualified platforms.

Sustained-load behaviour with ECC registered design

Registered buffering and on-die ECC maintain data integrity during continuous, heavy workloads such as virtualization, database processing and large-scale rendering. The 2Rx4 organization and CL40 latency deliver stable throughput at the rated 4800 MT/s without the variability seen in unbuffered consumer modules under prolonged stress.

Thermals noise and power at 1.1 V operation

Operating at 1.10 V, the module runs cool without a heat spreader, relying on chassis airflow for passive cooling. The low voltage reduces system power draw compared to higher-voltage DDR5 variants. Silent operation is assured because no active cooling is required on the DIMM itself.

Questions about this item

Does the 1.1 V operating voltage keep power draw and heat low during 24/7 server workloads?

At 1.1 V the 64 GB DDR5 4800 module draws minimal power, helping reduce heat output in continuously running registered ECC configurations.

Must the motherboard support registered ECC DDR5 RDIMMs for this module to function?

Yes, the 288-pin RDIMM requires a platform that accepts registered ECC DDR5 memory; it will not work in unbuffered or non-ECC slots.

Can this 2Rx4 CL40 stick be mixed with other registered DDR5 modules of different rank or speed?

Mixing is possible only if the motherboard validates the combined population; the module runs at DDR5 4800 CL40 1.1 V and the system will negotiate a common speed.
