ASRock TRX50 WS compatible DDR5 RDIMM

This 32 GB registered DDR5 module is built for the ASRock TRX50 WS workstation motherboard. It targets professionals who need ECC protection for data integrity in server and workstation workloads.

32 GB capacity with CL40 latency at 4800 MT/s

The single 1Rx4 rank delivers 32 GB of registered memory at 1.1 V. It handles multi-threaded compute and virtualization tasks comfortably, while the CL40 timing and single-module design limit maximum bandwidth compared to multi-channel populations.

No heat spreader included in the package

The bare module ships without a thermal spreader, so airflow across the PCB must be provided by the chassis. Installers should verify that the workstation cooling design moves sufficient air over the DIMM slots.

Questions about this item

Will this 4800 MHz ECC RDIMM run reliably alongside slower DDR5 modules I already have in the ASRock TRX50 WS?

All installed DDR5 modules will operate at the speed of the slowest module; mixing different speeds is possible but the system will downclock to the lowest common frequency.

How can I verify the module is detected correctly at 4800 MHz with ECC active after installation?

Enter the BIOS or use a hardware monitoring tool to confirm the memory reports 4800 MT/s, CL40 timings, 1.10 V, and shows ECC status as enabled.

Does the package include only the single 32 GB RDIMM or are extra items like a heat spreader or screwdriver supplied?

The box contains only the 32 GB (1x32 GB) DDR5 4800 CL40 ECC RDIMM module; no heat spreader, tools or additional accessories are included.
