CPU Socket & Generation Support

This GIGABYTE Z390 D motherboard uses the LGA 1151 socket and the Intel Z390 chipset. It supports 8th and 9th generation Intel Core i7, i5, i3, Pentium and Celeron processors. The board delivers a standard ATX form factor measuring 30.5 by 22.5 cm.

Memory Capacity & Target Builder

Four DDR4 DIMM slots accept up to 128GB of system memory. This capacity suits enthusiasts building a high-RAM workstation or gaming rig on the LGA 1151 platform. Builders needing newer CPU generations or different memory types should select a board with the appropriate socket and chipset.

Primary Expansion Slot

A single PCI Express x16 slot operating at x16 provides the main graphics card connection. Installing the GPU in this slot ensures maximum bandwidth for the card. The board also includes an M.2 interface and six SATA III ports for storage expansion.
