16 GB DDR5 ECC RDIMM for ASRock TRX50 WS

This 16 GB DDR5 4800 registered DIMM is built for the ASRock TRX50 WS workstation motherboard. It delivers error-correcting code protection for data integrity in professional workloads. The module runs at 1.1 V with CL40 latency.

Registered ECC with 1Rx8 organisation

The single-rank 1Rx8 layout and registered buffer reduce electrical load on the memory controller, allowing stable operation at DDR5 4800 (PC5-38400). ECC corrects single-bit errors to prevent silent data corruption. This specification determines compatibility with the target platform.

Simple DIMM installation.

The 288-pin DDR5 form factor fits the standard slots on the ASRock TRX50 WS. Insert the module until the retention clips click. Always check the motherboard vendor's qualified-vendor list before purchase; unsupported modules may fail to post or run at reduced speeds.

Questions about this item

What does the 4800 MT/s speed mean for my ASRock TRX50 WS workstation?

The module runs at DDR5 4800 (PC5-38400) so the memory controller will operate at that data rate, delivering the rated bandwidth for registered ECC workloads on the TRX50 WS platform.

How does the registered ECC design affect compatibility with the TRX50 WS motherboard?

This is a 288-pin DDR5 RDIMM with on-board register and ECC; the TRX50 WS chipset supports registered ECC DIMMs, so the module installs directly into the server DIMM slots without buffering conflicts.

Will the 1Rx8 16 GB stick fit the DIMM slots on my TRX50 WS board?

Yes, it uses the standard 288-pin DDR5 RDIMM form factor, 1.10 V operation, and single-rank x8 organisation that the TRX50 WS DIMM sockets are keyed for.
