Capacity and purpose

This 128GB kit provides eight 16GB DDR5 5600 CL36 registered ECC modules for W790 workstation motherboards. It targets professionals who need high-capacity, error-correcting memory for stable compute workloads. The 1Rx8 organisation and 1.25V operation suit qualified platforms that require registered DIMMs. Desktop PCs and laptops cannot use these modules.

Registered ECC and XMP behaviour

Registered buffering reduces electrical load on the memory controller, allowing the full eight-module population at rated speed. On-die ECC detects and corrects single-bit errors to protect data integrity during long jobs. Intel XMP support lets the firmware apply the 5600 MT/s profile with 36-38-38-80 timings without manual tuning. The kit is validated for the Asus Pro WS W790E-SAGE SE motherboard.

Build and thermal monitoring

Each module uses SK Hynix ICs on a ten-layer PCB under an integrated heat spreader. A built-in thermal sensor reports temperature to the platform, helping the system manage airflow within the 0 to 85°C operating range. The 288-pin RDIMM form factor fits only workstation sockets that accept registered memory, so builders must confirm motherboard compatibility before purchase.

Questions about this item

Will the 288-pin DDR5 RDIMM modules need any firmware updates or periodic re-seating over their lifespan?

No firmware updates are required for these registered DIMMs; the built-in thermal sensor monitors temperatures from 0 to 85 °C and the 10-layer PCB construction is designed for long-term reliability without scheduled maintenance.

What is the first limit reached when running all eight 16 GB modules continuously at 5600 MHz CL36?

The operating temperature ceiling of 85 °C is the primary sustained-use limit; the thermal sensor and heat spreaders manage heat, but prolonged heavy loads can push modules toward this threshold.

How much noise and heat do the modules produce when the workstation runs all day at 1.25 V?

The modules are passively cooled with heat spreaders and have no moving parts, so they generate no noise; heat output is managed within the 0–85 °C operating range by the onboard thermal sensor.
