System-specific DDR5 ECC RDIMM kit

This 64 GB kit delivers two 32 GB registered DDR5 modules rated at 4800 MT/s with CL40 latency and 1.1 V operation. ECC and registered buffering provide the data integrity required by the ASRock W790 WS workstation platform. The 288-pin RDIMM form factor matches the motherboard memory slots exactly.

Workstations needing registered ECC memory

Suited for builders populating an ASRock W790 WS board with validated registered ECC modules. Not suited for systems that require unbuffered non-ECC memory or that cannot accept registered DIMMs. Buyers needing lower latency or higher frequency kits should look at different specifications.

Registered ECC with 1Rx4 organisation

The modules use a 1Rx4 rank configuration with on-die ECC across major OEM DRAM from Samsung Micron or Hynix. This organisation determines electrical loading and compatibility with the workstation memory controller. Verify that the platform supports 1Rx4 registered ECC before purchase.

Questions about this item

Will 4800 MT/s DDR5 run at that speed on an ASRock W790 WS board?

The kit is validated for DDR5 4800 (PC5-38400) on the ASRock W790 WS workstation motherboard and will operate at that data rate when installed in supported slots.

Does the registered ECC design change what the DDR5 slot can accept?

These are 288-pin DDR5 RDIMMs with on-die ECC and a register; they require a motherboard that supports registered ECC DDR5, which the W790 WS provides.

What physical clearance do the two 32 GB modules need?

Each module is a standard-height 288-pin DDR5 RDIMM without a heat spreader, so they fit in any W790 WS DIMM slot with normal CPU-cooler clearance.
