256GB DDR4 ECC UDIMM kit

This 256GB kit contains eight 32GB DDR4 3200 ECC UDIMM modules built for the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard. It targets workstation and server builders who need registered-grade capacity in an unbuffered form factor. The modules run at 1.2V with CL22 latency and use 2Rx8 organisation across 288 pins.

Sustained-load behaviour

All modules are stress tested under load to verify stability during extended compute sessions. ECC error correction protects data integrity throughout long rendering, virtualization or database workloads. The 1.2V operating voltage helps maintain consistent thermals when all eight slots are populated. No heat spreaders are fitted, so chassis airflow must handle the thermal load.

Pre-order checklist

Confirm the motherboard supports 256GB of DDR4 3200 ECC unbuffered UDIMM across all eight slots. Verify the BIOS version enables full capacity and 2Rx8 module recognition. Ensure the operating system and applications can utilise ECC functionality. Check that the case provides adequate airflow over bare modules without spreaders.

Questions about this item

How much power do the 1.20 V 3200 CL22 modules draw when the system runs all day?

Each 32 GB stick operates at 1.20 V, the standard DDR4 voltage, so total power scales with the eight-module kit and your CPU load rather than a fixed wattage figure.

What must the motherboard provide for this 256 GB kit to function?

The board needs eight free 288-pin DDR4 slots that accept unbuffered ECC UDIMMs and a BIOS able to address 256 GB at 3200 MT/s with CL22 timing.

Will the 2Rx8 organisation of these sticks work with single-rank DDR4 modules I keep from an older build?

Mixing 2Rx8 modules with single-rank DDR4 is possible if the motherboard supports mixed-rank populations, but the memory controller will run all channels at the slowest common speed and latency.
