ASUS-compatible 16 GB DDR4 3200 UDIMM

This 16 GB DDR4 3200 module runs at 1.20 V with CL22 latency and a 1Rx8 layout. It is an unbuffered, non-ECC 288-pin UDIMM built with major OEM chips and validated for ASUS Prime B450M-A II, Prime B550M-A WiFi II, Prime X570-PRO and Prime B550M-A motherboards. The single-stick kit adds capacity without occupying extra slots.

Upgrading from 8 GB or lower on a supported ASUS

Moving from 8 GB to 16 GB on these Prime platforms removes the most common bottleneck for multitasking and heavier workloads. The jump is worth it when the system currently runs a single 8 GB stick or two 4 GB sticks and you have a free UDIMM slot. It is not for buyers who need ECC error correction or registered modules for server platforms.

Check DDR4 UDIMM slot availability

Verify the motherboard has a free 288-pin DDR4 UDIMM slot and that the BIOS recognises 3200 MT/s at 1.20 V. Confirm the board is one of the listed Prime models; other ASUS boards are not validated by this kit. Do not install in systems that require ECC, registered DIMMs or DDR5 memory.

Questions about this item

Does the 288-pin DDR4 UDIMM fit the ASUS Prime B550M-A WiFi II motherboard?

Yes, the 288-pin DDR4 UDIMM is listed as compatible with the ASUS Prime B550M-A WiFi II and other named ASUS motherboards.

Do I need to enable XMP in the BIOS for the CL22 3200MHz speed, or does it run at that speed by default?

The module is rated DDR4 3200 (PC4-25600) CL22 at 1.20V; it will run at JEDEC standard speed without enabling XMP.

The stick has no heat spreader — will it need active airflow or replacement sooner?

Standard DDR4 UDIMMs without spreaders operate within spec at 1.20V; no extra cooling or scheduled replacement is required.
