32 GB DDR5 ECC RDIMM kit for ASRock TRX50 WS

This 32 GB kit contains two 16 GB DDR5 4800 registered DIMMs with ECC and a CAS latency of CL40. It is built for the ASRock TRX50 WS workstation motherboard and targets professionals who need error-correcting memory for stable operation in demanding workloads. The modules run at 1.1 V and use a 1Rx8 organisation.

Registered 288-pin design without heat spreaders

Each module uses the standard 288-pin DDR5 RDIMM form factor and is registered to reduce electrical load on the memory controller. No heat spreaders are fitted, so the modules rely on chassis airflow for cooling. Builders must ensure their case and CPU cooler layout provides sufficient air movement across the bare PCBs.

Two-module kit validated for compatibility

The package supplies the matched pair of 16 GB DIMMs tested for the specified platform. No additional software, cables or mounting hardware are included. Buyers who need larger capacities or non-ECC unbuffered memory for consumer boards cannot use this kit.

Questions about this item

What speed does the DDR5 4800 kit run at on the ASRock TRX50 WS?

The modules are rated for DDR5 4800 (PC5-38400) with CL40 latency and operate at 1.10 V on the ASRock TRX50 WS workstation motherboard.

What physical slot and module height must the case accommodate?

Each module is a 288-pin DDR5 RDIMM without a heat spreader, so the case only needs to clear standard-height registered DIMMs in the motherboard's DIMM slots.

How are the two 16 GB sticks installed, and what step is often missed?

Insert both sticks into the correct DIMM channels for dual-channel operation, pressing until the retention clips click, and verify the BIOS recognises the full 32 GB ECC RDIMM kit.
