System-specific DDR5 ECC kit

This 32 GB kit contains two 16 GB DDR5 4800 modules built for the ASRock W790 WS workstation motherboard. Each stick is a registered RDIMM with ECC and a CL40 latency rating.

Verify registered DIMM support

Confirm that your W790 WS board accepts registered ECC memory and that the BIOS is current before installing. The kit runs at 1.1 V and uses the standard 288-pin DDR5 form factor.

Plain green PCB, no heat spreader

Modules ship without a heat spreader, so airflow across the DIMM slots is the only cooling. The 1Rx8 organisation and major OEM chips keep the layout clean for dense server or workstation builds.

Questions about this item

Does the 32 GB kit include both 16 GB DDR5 RDIMM modules or must I buy a second kit?

The package contains two 16 GB DDR5 4800 CL40 ECC RDIMM modules for a total of 32 GB; nothing else is required to populate two slots.

How do I decide between this 32 GB kit and a larger capacity for the ASRock W790 WS?

Choose this 32 GB (2 x 16 GB) kit when two slots are available and 32 GB meets the workload; add another identical kit later if the board has free slots and more capacity is needed.

What does the 4800 MT/s rating mean once the modules are installed in the W790 WS?

The memory will run at DDR5 4800 (PC5 38400) with CL40 latency at 1.10 V, providing registered ECC operation at the rated speed on the compatible motherboard.
