ASRock H170 Pro4 LGA 1151 ATX Motherboard

This ATX motherboard uses the Intel H170 chipset and an LGA 1151 socket. It provides four DDR4-2133 DIMM slots for up to 64 GB of non-ECC unbuffered memory. Expansion includes two PCI-Express 3.0 x16 slots, with the second running at x4, plus three PCI-Express 3.0 x1 slots. Storage connectivity covers six SATA3 ports with RAID 0, 1, 5, 10 support and one SATA Express 10 Gb/s port. Onboard audio uses the Realtek ALC892 7.1-channel codec.

Suitable for standard desktop builds needing

The board fits builders who want a full-size ATX layout with multiple expansion slots and plenty of SATA ports. It is not suited for users who require ECC memory, registered DIMMs, or memory speeds above DDR4-2133. Buyers needing more than two full-bandwidth PCI-Express x16 slots should consider a different platform.

Maximum memory capacity of 64 GB DDR4-2133

Four DIMM slots limit the total to 64 GB when populated with 16 GB modules. This ceiling is set by the slot count and the supported memory standard. Verify your workload fits within this limit before purchase.

Questions about this item

What size ATX case is required to fit this motherboard?

The board uses the standard ATX form factor, so any case that accepts ATX motherboards will accommodate it without modification.

How is the CPU installed into the LGA 1151 socket, and what step is often missed?

Lift the socket lever, align the processor notches with the socket keys, place it gently without force, lower the lever, then secure the retention bracket — forgetting the bracket is the common error.

Which components on this board may need replacement after several years of use?

The Realtek ALC892 audio codec and SATA connectors are soldered and not user-replaceable; the only routine replacement is the CMOS battery when system time drifts.
