64 GB DDR5 4800 ECC RDIMM for ASRock W790 WS

This registered DDR5 module provides 64 GB of ECC memory at 4800 MT/s with CL40 latency. It is built for the ASRock W790 WS workstation motherboard and operates at 1.10 V using a 288-pin RDIMM form factor.

Sustained load behaviour with registered ECC

The registered design places a register between the DRAM and the memory controller, reducing electrical load during continuous operation. ECC circuitry corrects single-bit errors on the fly, maintaining data integrity through extended compute sessions.

DDR5 RDIMM practical limits

DDR5 RDIMM topology supports higher module densities than unbuffered alternatives, but the memory controller must support registered signalling and ECC. The 4800 MT/s speed and CL40 timing define the bandwidth and latency ceiling for this configuration.

Questions about this item

How much heat does the 1.10 V DDR5 4800 RDIMM produce when running continuously?

At 1.10 V the module draws less power than higher-voltage DDR5, so thermal output stays modest inside a server chassis with normal airflow.

Does the ASRock W790 WS motherboard need any special BIOS setting to recognise this ECC RDIMM?

The board is designed for DDR5 4800 ECC RDIMMs; enabling ECC in the firmware is the only typical step required.

Will the 2Rx4 organisation work alongside single-rank DDR5 modules already in the W790 WS?

Mixed-rank populations are supported by the W790 WS chipset, though the system will run all channels at the lowest common speed and latency.
