Eight-module 256 GB DDR4 3200 CL22 kit for ASUS TRX40 ROG Zenith II Extreme motherboards
This 256GB kit contains eight 32GB DDR4 UDIMM modules built for the ASUS TRX40 ROG Zenith II Extreme motherboard. The memory runs at 3200MHz with CL22 latency at 1.20V. It targets workstation builders who need maximum capacity on this specific platform. The modules use Samsung, Micron or Hynix chips and carry a lifetime replacement warranty.
The kit suits professionals upgrading an ASUS TRX40 ROG Zenith II Extreme system to 256GB for virtualisation, rendering or large datasets. It is not for standard consumer motherboards that cannot address this density or that require registered memory. Buyers needing ECC error correction or lower-voltage DDR5 modules should look elsewhere. The unbuffered design limits use to platforms supporting 2Rx8 UDIMM topology.
This single figure decides fitment because the motherboard must support eight slots and 32GB per DIMM density. The 2Rx8 organisation and 1.20V operation are fixed by the kit design. Verify the board specification for maximum capacity per slot before purchase. No other capacity option exists in this package.

Yes, the 288-pin DDR4 UDIMM form factor matches the motherboard's DDR4 DIMM slots for direct installation.
Fill all eight slots to reach 256GB; the step often missed is enabling the 3200 MT/s speed in the BIOS, as the system may default to a lower JEDEC frequency.
No firmware updates or component replacements are needed; the modules are validated for stability at 1.20V CL22 and carry a lifetime replacement warranty.
