Capacity and configuration

This kit delivers 256GB of DDR4 server memory as two 128GB RDIMMs running at 3200 MT/s with CL22 latency. It targets administrators and integrators who need maximum registered ECC capacity in compatible ASUS workstation or server platforms.

Platform and slot verification

Confirm the motherboard supports 4Rx4 registered DIMMs at this density and that the BIOS recognises 128GB modules before ordering. The kit is validated for the ASUS Pro WS WRX80E-SAGE SE WiFi; other boards require manual qualification.

Build and daily implications

Modules use major OEM Samsung, Micron or Hynix chips on standard 288-pin PCBs without heat spreaders, operating at 1.2V. The registered buffer adds electrical load on the memory controller, so populate slots per the board manual to maintain signal integrity.

Questions about this item

Does the kit ship as two 128 GB RDIMMs or do I need to buy a second module separately?

The kit contains two 128 GB DDR4 3200 RDIMMs, giving 256 GB total; no additional modules are required.

When should I choose this 256 GB CL22 4Rx4 kit instead of a lower-capacity or dual-rank alternative?

Choose this kit when the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard needs maximum registered ECC capacity at 3200 MT/s and the 4Rx4 organisation is supported by the platform.

What does the 3200 MT/s rating deliver once the modules are installed in the server?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.20 V, providing registered ECC throughput supported by the compatible ASUS workstation board.
