Workstation DDR5 RDIMM kit

This 64 GB kit contains four 16 GB registered DIMMs built for Intel W790 workstation motherboards. Each module runs at DDR5 6800 with CL34 timings and includes on-die ECC for data integrity. The kit targets professionals who need high-capacity, error-correcting memory for compute-intensive workloads.

DDR5 6800 registered ECC limits

Registered DIMMs require a workstation platform with a compatible registered-memory controller; they will not function in standard desktop or laptop boards. The 1.4 V operating voltage and XMP profile demand a motherboard that can supply and validate that voltage. Operating temperature is rated from 0 to 85 °C, so adequate chassis airflow is necessary for sustained loads.

Premium build with thermal monitoring

Modules use SK Hynix ICs on ten-layer PCBs and carry aluminium heat spreaders for heat dissipation. A built-in thermal sensor reports module temperature to the platform for proactive throttling. The 288-pin RDIMM form factor fits only W790 workstation slots, so buyers must confirm motherboard compatibility before purchase.

Questions about this item

Should I pick the 64GB kit or a smaller capacity for my W790 workstation?

This kit provides 64GB total across four 16GB modules, which fills four slots on W790 motherboards and is sized for multi-threaded workloads.

What does the 6800MHz speed mean once the memory is installed in a W790 system?

The modules run at DDR5 6800 (PC5-54400) with Intel XMP, delivering that data rate when the profile is enabled on a compatible W790 board.

How does the registered ECC DDR5 interface affect real-world stability?

Registered ECC DDR5 adds a register and error-correction, improving signal integrity and data accuracy for workstation workloads on W790 platforms.
