In a move that's possibly triggered by the MSI MEG B550 Unify X, GIGABYTE unveiled a limited edition variant of its X570 AORUS Master motherboard targeting overclockers—the X570 AORUS Master OC. This board does away with much of its aesthetic cladding, sheds the rear I/O shroud, and exposes its bare PCB for the most part. A much simpler fan-heatsink cools the X570 chipset. The CPU VRM area is cooled by a pair of aluminium fin-stack heatsinks that are joined by what looks like a flattened heat-pipe.

Perhaps the biggest design change with the GIGABYTE X570 AORUS Master OC has to be its memory set-up. The board has just two DDR4 DIMM slots, or one DIMM per memory channel. From a memory overclocking standpoint, this is the most optimal memory topology, and the reason why memory overclocking records are usually set on Mini-ITX motherboards (that have 1DPC memory configuration). Elsewhere we see a pair of PCI-Express 4.0 x16 slots wired to the CPU (x8/x8 with both populated), a third PCI-Express 4.0 x16 (electrical Gen 4 x4, wired to the X570 chipset), and three M.2 NVMe slots, each with PCI-Express 4.0 x4 wiring.
