Updated review after long use

Pros: I'm currently using 2 of these boards for the last few years and I'd give them an 8 out of 10. I haven't had any stability issues with them at all. They are great boards for using a CPU that will work with Win7. It can be a bit of a problem to get that initial install tho but once you get it going with Win7 then you are good. I've also used this board with multiple Linux OS's without issue (in fact it works better then Windows, will explain in the Con Section).

Cons: I only have 2 issues with this board, one of which is Intel's fault and NOT ASRock's.
1) My first issue is the USB on this board. It is flakey as all heck! It will often glitch out on a given port if you plug a USB drive in and then take it out and then plug it back in to the same port. It won't recognize the drive again and you will need to switch to a diff port to make it work. This is an issue on both my board regardless of the OS I'm using. On my main computer I actually broke down and bought an aftermarket USB card and stopped using onboard.
2) First off i want to say, thanks ASRock for using an Intel NIC instead of lowgrade Realtek. Having said that, the Intel NIC will often disconnect in windows. Win7 or Win10, it doesn't matter. This does not happen with Linux OS's tho. After a lot of work and trial and error I've found the cultprit is the Intel Pro-Set drivers. If you install them they put the adapter into low power mode which causes disconnects, even if you are using the NIC!. The fix for this is just to use Intel or MS basic drivers and disable all "power saving" options. Then the NIC works perfectly.

Dead on arrival - Christmas Gift - "One bad egg does ruin the whole bunch"

Pros: Once I figured out the problem by myself!! this motherboard preforms superb & still is.

Cons: When the board arrived it was a Christmas gift for my son. I followed all the details and was able to move everything over from the previous PC. But once it was assembled and I turned the switch on nothing happened. My son was devastated and I was shocked, I went through the process again and reassembled still no power no nothing. I went and purchased a different power supply and still nothing but on a gut feeling I replaced the Cmos battery and bam it came on and worked superbly from then on. Once ASRock opened up after the holiday I called their number and explained what happened and was told straight up by their repair engineer that it was impossible and that there must have been something else that wasn't connected I must have knocked it in place. Very disapointed I called New Egg and explained the situation about the Cmos battery being dead (I checked with ohm meter) they refunded me $7 for the cost of the new one. But the point is without dumb luck I would to have returned the board which would have taken weeks to get it back to me. For that I will be more careful on what brand I buy . P.S. It had a rebate for the board and it was denied sent back to me blank.

Other Thoughts: Great board if it arrives alive and is working very disappointed in the AsRock support and lack of belief in their customers. New Egg did give me $7 refund but they were not stellar either in their support of the product they sold me. To top if off the $10 or $20 rebate was denied (after 6 weeks in space) for some reason lack of missing barcode even though receipt & cut out box code was included. Poorly handled by both parties all I can say is keep the pricing low because you dont offer anything else to guarantee customer respect or

Bad PCIe-3 slots

Pros: - Great specs for a high-performance HTPC
- Newegg has a great return policy

Cons: - PCIe-3 slot was bad across several boards

Other Thoughts: I spec'd out this board for a Home Theater PC build I was undertaking. The first board sent by NewEgg proved to have a bad PCIe-3 slot, which I confirmed using two known-good PCIe cards from different manufacturers (e.g. both cards worked fine in PCIe-1, 2, and 4; neither card worked in PCIe-3). Since I needed all four PCIe slots for the various components I was building into the HTPC, I returned the board for a replacement. The replacement board also had a bad PCIe-3 slot, and thus was returned for a refund.

At this point I considered the possibility that these two boards had come from one particular bad batch of motherboards, and so ordered another Z270M Pro4 from another online retailer in the hopes that this board might have come from a different batch. No dice: the third board also had a bad PCIe-3 slot.

This motherboard looks great on paper, and I'm disappointed that I could not find an example with a full set of working PCIe slots. I have been very happy with the ASRock motherboard I selected for another computer, an ATX desktop build. If you don't anticipate ever using all 4 PCIe slots, this board may work well for you. But without its full expansion capabilities, I'm unable to give this product more than 2 stars.

First was DOA, second works

Pros: Small form factor and inexpensive.

CPU Graphics compatible.

M.2 PCI Gen 3x4.

Plenty of 3.0 USB ports.

Cons: Newegg says the board has USB 3.1 ports. It does not. False advertising.

Only one 2.0 USB port on the back.

Other Thoughts: I wouldn't purchase this MB again since I was specifically looking for a MB with USB 3.1

Excellent ATX Micro board!

Pros: - Easy to install
- Lots of bells and whistles in such a small form factor board
- ASRock quality is always top-notch
- Very inexpensive (especially with rebate)

Cons: - Could use at least one more chassis fan header
- Would love it if "Crashless BIOS" was on this board as it is on my ASRock z97 Extreme6
- Would prefer to see USB 3.1 Gen2 on motherboard

Other Thoughts: Excellent little motherboard! I've never built around a Micro ATX motherboard. This was for a small media center computer. Surprising to see two m.2 slots on the board. Impressive and clean layout. Excellent and easy to use ASRock HD BIOS. I'd recommend this motherboard and I'd choose it for a similar project in the future.
