GIGABYTE B365 HD3 Intel Motherboard LGA 1151

SKU CH-33PG-FX1PJ

ATX board with Intel B365 chipset, LGA 1151 socket for 8th and 9th Gen Core CPUs, four DDR4 slots up to 64 GB, dual M.2 and six SATA 6Gb/s ports, Realtek GbE LAN and ALC892 audio

  • ProcessorSupport for 9th and 8th Generation Intel Core i9/i7/i5/i3 pr
  • ChipsetIntel B365
  • Form factorATX
  • CPU socketLGA 1151 (300 Series)
  • Onboard video chipIntegrated Graphics Processor-Intel HD Graphics support: 1 x
  • Memory slot count4 × 288pin (DDR4)
  • Supports 9th and 8th Gen Intel Core processors via LGA 1151 socket
  • Dual-channel DDR4 up to 64 GB at 2666 MHz for responsive multitasking
  • Two M.2 slots with PCIe 3.0 x4 and SATA for fast storage expansion
  • Realtek ALC892 audio with 7.1-channel support and noise guard for clear sound
  • Intel GbE LAN with bandwidth management for stable wired connectivity

Socket Compatibility

The board uses the LGA 1151 socket for Intel 300 series chipsets and accepts 8th and 9th generation Core i9, i7, i5, i3, Pentium and Celeron processors. It is not compatible with older LGA 1151 CPUs so the processor choice decides whether the motherboard works at all.

Memory Configuration

Four 288 pin DDR4 slots support dual channel operation up to 64 GB total capacity with native speeds of 2666, 2400 and 2133 MHz. XMP profiles are supported when paired with a 9th or 8th generation Core i9, i7 or i5 CPU so memory performance scales with the processor installed.

Expansion and Storage Layout

One PCIe 3.0 x16 slot runs at full x16 speed for a graphics card while four x1 slots and two M.2 sockets add further expansion. Six SATA 6Gb/s ports provide traditional drive connections and both M.2 slots accept 2242, 2260 and 2280 form factors with one also supporting 22110 length drives.

Questions about this item

What does the 64 GB maximum memory mean for my build?

You can populate all four DDR4 slots with up to 64 GB total, running in dual-channel mode at 2666, 2400 or 2133 MHz depending on the modules and CPU installed.

How fast is the M.2 Socket 3 M key slot in practice?

The primary M.2 connector supports PCIe 3.0 x4 and SATA SSDs up to 22110 length, so a PCIe 3.0 drive will run at its rated Gen3 speeds.

What case and power clearances does this ATX board need?

The board follows standard ATX dimensions, requires a 24-pin ATX power connector plus an 8-pin CPU power connector, and fits any ATX-compatible chassis with the usual I/O shield cutout.
