128GB DDR4 ECC kit for ASUS WRX80E workstations

This 128GB kit contains four 32GB unbuffered ECC UDIMMs rated at DDR4 3200 with CL22 latency. It targets IT professionals and workstation builders who need validated memory for the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard.

ECC protection and tested compatibility

Error-correcting code detects and corrects single-bit errors to maintain data integrity during sustained workloads. Each module is stress-tested under load before shipping, and the kit is configured specifically for the listed ASUS server motherboard to avoid compatibility issues.

Unbuffered 288-pin modules at 1.2V

The 2Rx8 modules operate at 1.20V without heat spreaders, fitting standard 288-pin DDR4 slots. Unbuffered design keeps latency low for workstation tasks, while the four-module population fills quad-channel architectures on supported boards.

Questions about this item

Will the four 32 GB modules need any cleaning or thermal maintenance over time?

The kit has no heat spreaders, so only occasional dust removal from the DIMM slots is needed; no thermal paste or active cooling upkeep is required.

What stops the 3200 MT/s CL22 kit from running faster during a long render job?

The JEDEC-rated 3200 MT/s speed and CL22 latency are the fixed operating limits; the modules do not support higher frequencies or tighter timings.

How much power and heat will the 1.2 V 128 GB set add when the workstation runs all day?

At 1.2 V the four modules draw minimal power and produce little heat, and with no heat spreaders they rely on normal case airflow to stay cool.
