NEMIX RAM
Eight-module kit provides 128GB of DDR4-3200 UDIMM memory at CL22 and 1.2V for ASUS TRX40 motherboards
This NEMIX RAM kit delivers 128GB across eight 16GB DDR4 UDIMM modules rated at 3200MHz with CL22 latency. It is built for the ASUS TRX40 ROG Zenith II Extreme motherboard and suits workstations or high-end desktops that need maximum memory capacity for heavy multitasking or content creation.
The unbuffered non-ECC DIMMs use standard 288-pin DDR4 slots and operate at 1.2V, so they seat like ordinary desktop memory. Common issues arise when all eight slots are populated: the memory controller may downclock the kit below 3200MHz or require a manual voltage tweak in the BIOS to maintain stability.
Confirm your motherboard has eight DDR4 slots and that the CPU supports 128GB total capacity before ordering. Check that no oversized CPU cooler blocks the DIMM slots nearest the socket, as all eight modules must fit simultaneously. The kit has no heat spreaders, so module height is low, but physical clearance still matters.
