ASRock B365M Pro4 Motherboard Review

Today, we’ll be taking a quick look at the ASRock B365M Pro 4 Motherboard, which utilizes Intel’s latest B365 chipset and supports all of Intel’s 8th and 9th Gen Core processors LGA1151 (14nm Coffee Lake).

It comes in a micro ATX form factor and features 2 x M.2 lots for your SSDs, PCIE steel slot, Intel Gigabit LAN, 7.1 HD audio, and of course ASRock Polychrome RGB. It also supports Optane memory, memory speeds of up to DDR4 2666, AMD Quad CrossFireX™ and CrossFireX™ multi-GPU.

As I mentioned previously in my review of the ASRock B365 Phantom Gaming 4 motherboard …

The new B365 chipset from Intel is made using their 22nm fabrication process, as opposed to 14nm for their B360. This doesn’t necessary mean it’s old or bad … it’s just a way for Intel to free up some capacity for 14nm production, which they have been having problems with recently. Many have express concerns about going back to 22nm, especially when AMD have already released 7nm processors this year. 

The B365 chipset offer very similar features to the B360, with some difference being the number of PCI Express lanes of 20 for the B365 and only 12 for the original B360. Additionally, the B365 now supports hardware RAID for PCIe and SATA storage devices, something that’s missing on the B360. The downside is … the lack of integrated wifi, there’s no overclocking options and it can only support up to DDR4 2666 memory.



I would like to thank ASRock for providing the review sample. This is a snippet from what ASRock has to say about themselves on their website:

ASRock Inc. is established in 2002, specialized in the field of motherboards. ASRock strives to build up its own brand. With the 3C design concept, “Creativity, Consideration, Cost-effectiveness”, the company explores the limit of motherboards manufacturing while paying attention on the eco issue at the same time, developing products with the consideration of eco-friendly concept.



ASRock has been growing fast and become world third largest motherboard brand with headquarter in Taipei, Taiwan and branches in Europe and the USA. The young and vibrant company targets from mainstream to enthusiast MB segments for different kinds of users, owning reputation around the world market with its reliability and proficiency.


The ASRock’s Pro series may look a little conservative (i.e. no fancy gaming features), but it should perform just as good and any of their siblings of the same chipset. The micro ATX form factor of this motherboard will allow users to mount and install them on a lot of cases out there. So it’s perfect for anyone who wants to build a compact PC for both gaming and general use.

It will be interesting to see how this motherboard will perform against it’s sibling, the ASRock B365 Phantom Gaming 4, and other boards based on the B360, H370 and the Z390 … Let’s find out.

You can buy the ASRock B365M Pro4 Motherboard from various online retailers including Amazon for around USD $79 –
