Asus Prime A320M-A and ROG Maximus IX kit

This 64GB kit contains four 16GB DDR4 modules built for Asus Prime A320M-A and ROG Maximus IX series motherboards. It targets builders who need the maximum supported capacity on these specific boards.

DDR4 2400 speed ceiling

The modules run at 2400 MHz with CL17 timings and 1.2V voltage, matching the highest JEDEC speed these platforms guarantee without manual tuning. Faster XMP profiles are not validated by the manufacturer for this kit.

64GB across four slots

The motherboards provide four DIMM sockets and a 64GB maximum, so this four-stick kit fills every slot to reach that limit. Buyers who want more capacity cannot add modules beyond the board's physical and chipset ceiling.

Questions about this item

Should I choose the 64GB kit or a smaller capacity for my Asus Prime A320M-A?

The motherboard supports up to 64GB across four slots, so this 4x16GB kit fills every socket and reaches the maximum capacity the board can address.

What does the 2400 MHz speed mean once installed in my ROG Maximus IX Hero?

The modules run at DDR4 2400 (PC4 19200) with CL17 17-17-17 timing at 1.2V, delivering the rated frequency and latency without manual tuning.

Does the 288-pin DDR4 interface limit bandwidth on the Prime A320M-A?

The 288-pin DDR4 DIMMs operate at the board's native DDR4 2400 specification, so the interface does not impose any additional bottleneck beyond the memory controller's rated speed.
