Socket LGA 1151 uATX Motherboard

The ASUS PRIME H310M-K is a micro-ATX board built on the Intel H310 chipset for 8th generation Core i7, i5 and i3 processors. It fits compact cases while providing the essential connectivity for a mainstream desktop build.

Ideal for Office and Home Builds

This board suits users assembling a basic productivity PC or upgrading an older LGA 1151 system with two DDR4 slots and four SATA 6Gb/s ports. Builders who need multiple graphics cards, extensive USB 3.1 Gen 2 headers, or overclocking headroom should consider a different chipset.

Dual-Channel DDR4 up to 32 GB

The two 288-pin slots support DDR4 2666 memory in dual-channel mode with a maximum capacity of 32 GB. This memory ceiling is the key figure that determines whether the board matches the planned system RAM.

Questions about this item

What maximum transfer rate do the four SATA 6Gb/s ports deliver in practice?

The four SATA 6Gb/s ports each support up to 6 Gb/s, so a SATA SSD or HDD connected to any of them can reach its rated sequential speed without a bottleneck from the motherboard.

How much clearance does the uATX board need inside a case?

The board measures 8.9 inches wide by 7.3 inches deep, so any chassis that accepts Micro-ATX will have the required mounting holes and internal space.

What is the correct way to seat the DDR4 DIMMs and which mistake should I avoid?

Open the single retention clip on each 288-pin DDR4 slot, align the notch on the module with the slot key, press straight down until the clip snaps shut, and do not force a module in backwards — the notch position prevents that, but excessive pressure can damage the slot.
