ASUS-compatible DDR4 3200 kit

This 16 GB kit contains two 8 GB DDR4 3200 UDIMM modules built for ASUS Prime B550M-A WiFi II, Prime B450M-A II, Prime X570-PRO and Prime B550MA motherboards. Each stick runs at 1.2 V with CL22 timing and uses a 1Rx8 unbuffered non-ECC layout. The 288-pin form factor fits standard desktop DIMM slots.

Two matched modules in one package

The paired sticks are tested together so they initialise at the same speed and latency without manual tuning. No heat spreader is included, keeping the modules low-profile for tight CPU cooler clearances. The kit delivers the full 16 GB capacity in a single purchase, avoiding the need to source a second identical stick later.

Verify DDR4 slots and maximum capacity

Confirm your motherboard has free 288-pin DDR4 slots and supports 3200 MT/s operation at 1.2 V. Check the board manual for the maximum memory per slot and total system limit before ordering. Buyers who need ECC, registered modules or a different voltage should select another product.

Questions about this item

How often will the CL22 1Rx8 UDIMM modules need to be replaced in a desktop that runs continuously?

The modules are built with major-brand Samsung, Micron or Hynix chips and carry a lifetime replacement warranty; under normal desktop use they should not require scheduled replacement.

What is the first limit reached when the 3200 MT/s kit runs at full load for hours?

The CL22 latency and fixed 1.20 V voltage are the primary constraints; the memory controller will throttle before the modules exceed their rated speed.

How much heat and noise do the two bare 8 GB sticks add to a system running all day?

With no heat spreader and a low 1.20 V operating voltage, the sticks add minimal heat and produce no audible noise, relying on case airflow for cooling.
