Gigabyte has been making motherboards for a while, and this Z390 AORUS Ultra is their flagship offering. It is equipped with the latest hardware, including a dual channel DDR4 2666MHz memory, an Intel Optane memory module, and a USB 3.1 Gen 2 Type-C port.

This motherboard has a dual-channel DDR4 memory controller that supports both DDR4 and DDR3 memory modules, so it is compatible with both.

The board also has four DDR4 slots, which means you can add up to 16GB of RAM. However, since there are only two memory slots, you need to buy two of these motherboards to support 32GB of RAM. You can run DDR3 memory modules too, but that’s slower than DDR4, so you should stick with DDR4.

The Z390 AORUS Ultra has an advanced 12+1 power phase design, meaning there are 12 phases for CPU power plus 1 phase for the PCH. Its the same as we have seen in previous models, but this one has the power phase design on the CPU area instead of the PCH.

This way, it can deliver a more consistent voltage to the CPU and increase its stability. There is also an Intel CNVi 802.11AC 2×2 wave 2 Wi-Fi, which supports up to 1.73Gbps.

The motherboard has eight SATA 6Gbps ports, and you can use either M.2 slots to install a PCIe SSD or a SATA drive.

A PCI-E x1 slot is also useful for installing a sound card, USB 3.0 port, or even a small form factor drive.

The motherboard has an integrated rear-panel audio port and optical S/PDIF output for digital audio connection.

For connectivity, the board has six USB 3.1 Gen 2 Type-C ports and three USB 3.1 Gen 2 Type-A ports. There are also two USB 2.0 ports, one USB 3.0 port, and one FireWire port.
