64 GB DDR4 kit for ASUS Prime X299-A II

This 64 GB kit contains eight 8 GB DDR4 3200 UDIMM modules tested for the ASUS Prime X299-A II motherboard. The modules run at 1.2 V with CL22 latency and use major-brand DRAM chips. They are non-ECC, unbuffered, and have no heat spreaders.

Suited for full 8-slot population, not for ECC needs

Builders filling all eight DIMM slots on this specific board get a matched kit that simplifies installation. Systems requiring error-correcting code memory or registered modules cannot use these sticks. Buyers needing a smaller capacity or different speed should look at other kits.

Eight 8 GB modules at DDR4 3200 CL22

The kit delivers 64 GB total across eight single-rank 1Rx8 modules rated at PC4-25600. This exact module count and speed combination determines whether the motherboard can run the full population at the rated frequency without manual tuning.

Questions about this item

What motherboard must I already have for this 64 GB DDR4 3200 kit to be compatible?

The kit is validated for the ASUS Prime X299-A II motherboard, so that board must be installed before adding these modules.

Will the eight 1Rx8 modules run correctly alongside any existing DDR4 DIMMs I keep in the other slots?

Mixing ranks and capacities can work, but for best stability populate all eight slots with this matched 8 x 8 GB kit and remove older sticks.

How can I confirm the memory is operating at 3200 MT/s with CL22 timing after installation?

Enter the UEFI or use a tool such as CPU-Z to verify the memory frequency reads 3200 MT/s and the CAS latency shows 22.
