  • Tested compatible with Gigabyte X570 AORUS PRO series motherboards

Targeted Capacity and Compatibility

This kit delivers 128GB of DDR4 memory across four 32GB modules, validated for Gigabyte X570 AORUS PRO, PRO WIFI, and ULTRA motherboards. It suits content creators and workstation users who need large, stable capacity for multitasking, virtualization, or heavy application loads on these specific platforms.

Upgrade Path and Performance Threshold

The kit replaces lower-capacity DDR4 sets or mismatched sticks that limit total memory to 64GB or less, or force the system to run at slower speeds due to mixed timings. The jump is worth it when your workload regularly exceeds 64GB active usage, or when you want a matched 4x32GB configuration at 2666MHz CL19 to avoid downclocking.

Installation and Common Pitfalls

Installation follows standard 288-pin DIMM seating in the four motherboard slots; the modules are unbuffered, non-ECC, and operate at 1.2V with 2Rx8 organization. Common issues include failing to enable the correct memory profile in BIOS, mixing these sticks with slower or different-rank modules which forces all memory to the lowest common speed, and attempting to use the kit on unsupported boards where the memory controller cannot address the full 128GB.

Questions about this item

Will the 288-pin DDR4 DIMMs fit the four memory slots on my Gigabyte X570 AORUS motherboard?

Yes. The kit contains four 288-pin DDR4 unbuffered DIMMs designed for the four DIMM sockets on the X570 AORUS PRO, PRO WIFI and ULTRA boards.

What is the correct way to seat the 32 GB modules so the system recognises all 128 GB?

Align the notch on each module with the slot key, press straight down until both retention clips click, and populate all four slots as a matched quad-channel set.

When should I consider replacing these CL19 1.2 V modules?

Replace them only if memory diagnostics report errors or the system becomes unstable; otherwise the limited lifetime warranty from Computer Memory Solutions covers manufacturing defects.
