64 GB DDR4 kit for ASUS TRX40 systems

This 64 GB kit contains four 16 GB DDR4 3200 UDIMM modules built for ASUS motherboards using the TRX40 chipset. It targets workstation and high-end desktop builders who need maximum capacity on a validated platform. The modules run at 1.2 V with CL22 latency and use a 1Rx8 organisation.

Tool-free slot installation with manual verification

Each 288-pin UDIMM drops into standard DDR4 slots without tools or cables. The kit is unbuffered and non-ECC, so it must be used in consumer or workstation boards that accept unregistered memory. The most common issue is populating the wrong slots for quad-channel operation; consult the motherboard manual for the correct population order.

Verify TRX40 chipset and quad-channel slot layout

Before ordering, confirm your motherboard uses the AMD TRX40 chipset and provides four DDR4 UDIMM slots wired for quad-channel mode. The kit requires 1.2 V operation and CL22 timing support at 3200 MT/s. Systems limited to dual-channel architecture or registered DIMMs will not accept this configuration.
