16GB DDR4 3200 Kit for ASUS Prime X299-A II

This 16GB kit contains two 8GB DDR4 3200 UDIMM modules validated for the ASUS Prime X299-A II motherboard. Each stick runs at 1.20V with CL22 timing and uses a 1Rx8 organisation without ECC or a heat spreader.

Upgrade from lower capacity or slower DDR4

Replacing a smaller kit or slower DDR4 modules with this matched pair adds bandwidth and capacity for multitasking and memory-intensive workloads. The jump is worthwhile when the board has free slots and the current memory limits application performance.

Verify board revision and slot population

Confirm the motherboard is the Prime X299-A II revision before ordering. Check how many DIMM slots are already occupied and whether the CPU installed supports quad-channel operation, because the kit provides two modules for a four-channel platform.

Questions about this item

Will the 288-pin DDR4 UDIMM modules fit the ASUS Prime X299-A II motherboard slots?

Yes, the 288-pin DDR4 UDIMM form factor matches the motherboard's DIMM slots exactly.

Which slot pair should I populate first on the X299-A II for dual-channel operation with this 2x8GB kit?

Install the modules in the same-coloured slots, usually DIMM_A1 and DIMM_B1, to enable dual-channel mode.

Do these modules need any active cooling or thermal pad replacement over time?

No, the modules have no heat spreader and run at standard 1.20V, so no extra cooling or pad maintenance is required.
