128GB DDR4 3200 kit for ASUS boards

This 128GB kit contains four 32GB DDR4 3200 UDIMMs built for ASUS Prime B550M-A WiFi II, Prime B450M-A II and Prime X570-PRO motherboards. It targets desktop builders who need maximum capacity on these specific platforms. The modules are non-ECC and unbuffered for standard desktop use.

CL22 latency at 1.2V

The decisive specification is CAS latency 22 at the JEDEC-standard 1.2V operating voltage. This timing and voltage combination determines whether the kit runs at its rated 3200MT/s without manual adjustment on the supported ASUS boards. No heat spreader is fitted.

Four-slot population on supported ASUS boards

The kit fills all four DIMM slots on the listed ASUS Prime motherboards, delivering 128GB in a single matched set. It requires a board that accepts 2Rx8 288-pin DDR4 UDIMMs at 3200MT/s. Builds needing ECC or registered memory cannot use this kit.

Questions about this item

What does the 3200 speed mean once the kit is installed in my desktop?

The modules run at DDR4 3200 (PC4-25600) so the memory controller transfers data at 3200 MT/s, delivering the rated bandwidth when the motherboard enables the matching profile.

How does the 288-pin DDR4 interface limit what I can use this kit with?

The 288-pin UDIMM form factor fits only desktop motherboards with DDR4 slots; it cannot be used in laptops, servers that require registered DIMMs, or any board wired for DDR5.

What physical space and power do the four 32 GB sticks need?

Each stick is a standard-height 288-pin UDIMM without a heat spreader, draws 1.2 V, and the kit occupies four adjacent DIMM slots on the motherboard.
