GIGABYTE GA-Z170-D3H Intel motherboard

SKU CH-5XG2-74T61

An LGA1151 board for 6th and 7th generation Intel Core CPUs with four DDR4 slots, USB 3.0 Type-C, a PCIe Gen3 x4 M.2 slot up to 32Gb/s, three SATA Express ports up to 16Gb/s and 115dB SNR audio

  • CPU TypeCore i7 / i5 / i3 / Pentium / Celeron (LGA1151)
  • Supports 7th and 6th generation Intel Core processors on LGA1151 socket
  • Dual-channel DDR4 across four DIMM slots for flexible memory upgrades
  • Intel USB 3.0 with Type-C connector for modern peripheral compatibility
  • PCIe Gen3 x4 M.2 connector delivers up to 32Gb/s data transfer for NVMe and SATA SSDs
  • 115dB SNR HD audio with rear amplifier and noise guard for clear sound output

LGA1151 Platform Foundation

The GIGABYTE GA-Z170-D3H motherboard accepts 6th and 7th Generation Intel Core i7, i5, i3, Pentium and Celeron processors in the LGA1151 socket. It provides a stable base for mainstream desktop builds that do not require enthusiast-class chipsets.

Memory and Storage Headroom

Four DDR4 DIMM slots operate in dual-channel mode for ample system memory capacity. A PCIe Gen3 x4 M.2 connector delivers up to 32Gb/s for NVMe and SATA SSDs, while three SATA Express ports add up to 16Gb/s each for additional drives.

Interface Practical Limits

USB 3.0 with a Type-C port handles current peripherals but lacks the bandwidth of newer USB standards. PCIe Gen3 x4 caps M.2 throughput at 32Gb/s, so the fastest Gen4 and Gen5 NVMe drives cannot reach their rated speeds. SATA Express tops out at 16Gb/s per port.

Highlights

  • Supports 7th and 6th generation Intel Core processors on LGA1151 socket
  • Dual-channel DDR4 across four DIMM slots for flexible memory upgrades
  • Intel USB 3.0 with Type-C connector for modern peripheral compatibility
  • PCIe Gen3 x4 M.2 connector delivers up to 32Gb/s data transfer for NVMe and SATA SSDs
  • 115dB SNR HD audio with rear amplifier and noise guard for clear sound output

Questions about this item

Will my existing DDR4 memory modules work in the four DIMM slots on this GA-Z170-D3H board?

Yes, the board provides four DDR4 slots running in dual-channel mode, so any standard DDR4 DIMMs you already own will install and operate normally.

How can I verify the 115dB SNR audio and the rear amplifier are functioning after I build the system?

Play a high-resolution audio file in the OS, confirm the Realtek driver reports 115dB SNR, and listen for clean, amplified output from the rear panel jacks without hiss.

Which cables or adapters are included in the box, and what must I source separately for the M.2 and SATA Express connectors?

The retail package contains the motherboard, I/O shield, SATA cables, driver disc and manual; you must supply an M.2 NVMe or SATA SSD, SATA Express drives and any additional SATA cables you need.
