ASUS-Compatible DDR4 32 GB Kit

This 32 GB kit contains four 8 GB DDR4 UDIMMs rated at 3200 MT/s with CL22 latency and 1.2 V operation. It is built for ASUS Prime B550M-A WiFi II, Prime B450M-A II, Prime X570-PRO and Prime B550MA motherboards.

Tool-free DIMM slot installation

The unbuffered non-ECC modules insert directly into standard 288-pin desktop slots without extra cables or drivers. The main risk is mixing kits with different ranks or voltages, which can prevent the system from posting.

DDR4 platform ceiling

DDR4 tops out at the 3200 MT/s JEDEC rate used here, so faster data rates require a platform change. The four-slot layout also caps total capacity at this kit’s 32 GB unless higher-density modules are qualified for the board.
