GIGABYTE GA-Z170-HD3 are presented in the format ATX with a slightly reduced width. Final dimensions – 305×199 mm Model belongs to the classic series, Ultra Durable.
The circuit Board is made in black. This color has a textolite basis, the majority of connectors and elements of the cooling system. However, through the thickness of the varnish is clearly visible in the track conductors, because PCB itself is not deep black but rather dark brown color.
Power subsystem Board is built on 6-phase scheme, the parameters of which manages a discrete controller Intersil ISL95856. VRM elements arranged in one line closer to the top edge of the PCB. To cool the MOSFET is used an additional aluminum heatsink of medium size fastened with plastic latches.
Additional power is supplied via one 8-pin connector.
On the Board has 4 slots for memory modules DDR4. The total amount of RAM can be up to 64 GB. According to the specification, the claimed set support up to DDR4-3466. The connectors have one-way locking mechanism that simplifies installation/removing the modules with a dense arrangement of the system inside the case.
GIGABYTE GA-Z170-HD3 offers six slots for expansion cards. These are two full-length PCI Express x16 slot, a couple PCI Express x1 slots and the same number of PCI. Despite the fact that Intel Z170 allows to divide the processor line PCI Express, in this case this option is not implemented. First full slot always works in full speed mode, single-handedly getting all 16 lines PCI Express. The second slot gets 4 lanes from the chipset and operates at x4. In this configuration, it is impossible to realize a bundle of two graphics cards in SLI mode. At least NVIDIA does not certify devices that don’t offer at least a mode x8+x8. However, problems with CrossFire not expected. Two graphics cards with chips AMD will be working in pairs. When using the top wiedosari minimum loss during synchronization are possible, but they just will not compare to talking about a few percent. Yet, recall that the chipset Intel hundredth series has received support for PCI Express 3.0 and not 2.0, respectively a problem with lack of bandwidth will not.
