Capacity and purpose

This 64 GB kit contains four 16 GB DDR4 ECC UDIMM modules built for the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard. It targets workstation and server builders who need error-correcting memory for data-integrity workloads.

Speed ceiling and voltage

The modules run at DDR4 3200 (PC4-25600) with a CL22 latency at 1.20 V. Unbuffered ECC UDIMMs cannot exceed the platform's native memory-controller limits, so the kit operates within the board's qualified speed envelope without manual tuning.

Deciding specification

ECC unbuffered 288-pin DDR4 is the single trait that determines fit; systems requiring registered DIMMs, non-ECC memory, or a different pin count will not accept these modules.

Questions about this item

Should I choose the 4x16GB kit or buy single 16GB modules to reach 64GB?

The kit provides four matched 16GB modules tested together for 64GB total, ensuring dual-rank 2Rx8 operation and CL22 timing consistency across all slots.

What does the 3200MHz rating deliver on an ASUS Pro WS WRX80E-SAGE SE WiFi motherboard?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.20V, giving the rated bandwidth and ECC error correction when the board enables the XMP or JEDEC profile.

How does the 288-pin DDR4 ECC UDIMM interface limit maximum capacity per slot?

Each 288-pin UDIMM slot accepts one 16GB 2Rx8 module; the four-module kit reaches 64GB total, and the unbuffered ECC design works without registered DIMM circuitry.
