Layout
As we've already mentioned in the introduction the Gigabyte Z370 AORUS Gaming 3 motherboard comes with a great looking design. The PCB has a matte black finish and the heatsinks feature red accents. Apart from that the PCH received RGB backlight. The heatsinks have been shaped nicely and the whole product is really good looking. The layout has been well thought and there are plenty of useful features, like two headers to attach external USB 3.0 ports, six SATA 6Gbps ports (two straight) and two M.2 Gen 3 x4 slots. In addtion there is a plastic cover on the I/O ports.
The Gigabyte Z370 AORUS Gaming 3 comes with a digital 7 phase power design regarding the CPU. The CPU power design, which is controlled by an Intersil ISL95866 dual-loop multi-phase controller. Furthermore there are NTMFS4C06N and NTMFS4C09N MOSFETs from ON Semiconductor on the high- and low- side.
This board has been equipped with a total of four DIMM-slots. Officially supported is everything up to DDR4 4000 (O.C.). There is engough space between the DIMM-slots and the CPU socket which means that you wont encounter compatibility problems with big coolers even when you choose to install RAM with big heatspreaders. Also supported are Xtreme Memory Profiles (XMP) in version 2.0.
The PCH as well as the current converters are being held at adequate temperatures via passive heatsinks. The heatsink for the current converters are made from two aluminium blocks which are not linked with additional heatpipe. While the heatsink on the PCH has been secured with screws, the two small heatsinks used on the current converters sport a push-pin system. The PCH heatsinks are all quite simple and flat. The cooling blocks have been very well made and also they are perfectly attached to the board to provide enough pressure on the components they have to cool.
