Good while it lasted 2/25/2020 11:43:10 AM

Pros: Worked well and had a lot of features.

Cons: Died out of the nowhere. No problems just one day it would not turn turn on.
I don't know if it's a case issue or a motherboard issue but a top mount aio has little to no room to be mounted.

Overall Review: I liked the motherboard and it was fantastic after I got the first one rma'ed but I have a motherboard from 2010 that still works so I don't understand why this one failed after 2 and half years.

The best motherboard I have ever owned! 12/1/2018 3:03:40 PM

Pros: I absolutely LOVE this motherboard from ASRock! I have now been using it for 1 full year with an Intel i5 8600K @ 5GHz and it's been the perfect motherboard. Everything just works, temps are great, plenty of features, and BIOS updates have gone so smoothly.

Cons: I really can't think of any cons.

Overall Review: I would definitely recommend this board to everyone and will certainly purchase ASRock motherboards in the future!

Great Mobo for Price+Quality! 9/17/2018 12:15:40 PM

Pros: - Simple setup right out of the box
- ASRock Software allowed for easy updating of the firmware
- Simple UEFI bios
- RGB lighting was SUPER simple to setup
- Overclocking and RAID setup was EZ-PEAZY (see con)

Cons: - ASRock information online about setting up a RAID (I went with a RAID 0 with both of my M.2 SSD's) was quite dated and not very clear at some points. However a couple google searches and some videos on YouTube helped with making sure everything was properly configured.

Overall Review: Overall I'm very happy I bought this board, with all of the options that are out there. Overclocking the Intel i7 - 8700K was not a problem at all, and there are plenty of YouTube videos on how to do it correctly (Though, the ASRock UEFI makes it really easy).

There's alot of stuff you can do within the Advanced Mode - especially if you're one of those owners that loves to get under the hood with overclocking and completely control over your chip.

PLEASE NOTE: This review was written for the ASRock review rebate program.

UPDATE - 9/17/2018

I'm not sure if anyone has had the issues I have run into. But since ordering this motherboard and running it in my system, I've recently found that the RAID controller is complete garbage. I recently reformatted my computer and tried installing Windows 10 on the drives. For the life of me I could not get Windows 10 to install. I deleted the original RAID setup and created a new one. The motherboard did not recognize my second m.2 drive, and in some cases didn't even recognize my first one.

Suffice to say, the RAID controller stopped working. I attempted to install a new firmware version for the UEFI, but to no avail.

I've also run into issues where the sound cuts out every once in awhile. This may be a software issue, but rolling back drivers and/or installing new ones have provided no solutions.

I'll be shelling out 200 for a good motherboard. You definitely get what you pay for.

A dream to overclock on 8/7/2018 4:13:33 PM

Pros: - VRM Heat pipe
- Smart board layout
- Ample room for most things
- UEFI layout

Cons: - Fan header placement required some extensions for me (super minor and largely my fan's fault)
- No VRM heat sensor. I'm not sure if this board just doesn't need it, but it would be nice to have.

Overall Review: Well done ASrock. I really appreciate the easy to understand UEFI.

This board has all of the key features you'd expect from a high end board, without all the excess garbage that you'll never use.

Overall Review: The reviews you see on Alot of these z370 boards (Asrock, Msi, Gigabyte, Asus. for the most part all have some of the same bad reviews....

-"ram not posting to advertised spec" 1. You must enable XMP, 2. If you OC your Ram it will (by nature) increase your CPU Ghz. IT IS A TRADE OFF. You must first OC your CPU to desired GHZ and then fine tune your Ram speed to be stable. THIS IS NOT A PROBLEM WITH THE BOARD... If you cant hit your Rams Advertised OC speed. Every Board/cpu/ram combo is going to post diff results. it takes a fair amount of fine OC tuning to hit a good stable over clock. People don't understand this and leave bad reviews on products.

-"Vrm gets to hot" Ive seen this this review a couple of times.... And people are confused when the only fans they have in their PC are on there liquid cooled radiator fans in an "open case" design... YOU HAVE TO HAVE GOOD AIRFLOW OVER VRM HEAT SINKS/HEAT PIPE. If not the power phase/choke design can become unstable on ANY MOTHERBOARD! leading to higher CPU voltage spikes and causing Blue Screens Of Death...And Premature motherboard death, This is another thing some people do not understand.

-"this board advertises on board 4k at 60hz and only hits 30hz..."
1. No it does not advertise that. it advertises on board 4k @ 30hz.

-"RGB LED Ram lights Not functioning properly" This one is everywhere... on most boards, Its advertised by the boards supported ram list. Most Ram is AURA RGB capable which is ASUS and for ASUS boards only. That does not mean the Ram RGB wont work, It means the Ram RGB will do what it wants for coloring and cannot be controlled. This is not the Motherboards fault Since it is Literally advertised... Most people cant read apparently and blame Motherboards for it not doing what they assumed it would. my suggestion for this board, If you want LED Ram is just get a color you want and Breaths/stays steady for best results.

-"DOA" yes some boards come Dead on Arrival, BUT that is all boards. Ive read tons of reviews about DOA on every motherboard on the market. I can tell you this is most likely Shipping's fault. We have all seen the mail/ups carrier videos of how they treat packages... so lets not jump the gun and blame the MFG of the board. Just have it warrantied for idk...... FREE.

-The list goes, lots of bad reviews can be left from people that simply don't know what they are doing and immediately blame the Board. You can burn up a board from not knowing what you are doing when in OC and even killing a CPU. Its not the boards fault if you blast 5ghz at it with no airflow which leads it to fail after a month.

This is a great board, with plenty of function at a AMAZING price. You just have to do some research. I picked this board after 4 months of research for gaming. One final thought. Some people give it bad reviews after running hours of straight stress testing. I will never hardcore stress test this machine, it is hard on computers and is just not realistic in the gaming world. This board is for gaming and does that very well. Were Not dealing with a 3d Krakota movie making machine that needs to Render the making of transformers in 4k Imax, be realistic.

Great mobo, not so great lighting 7/10/2018 8:54:18 PM

Pros: -Solid mobo
-Easy to use BIOS
-VRM heatpipe (which should be used more often in other motherboards)

Cons: -A couple of red lights that you are unable to turn off.

Overall Review: I rated this 4 stars simply because of the lighting. There is no way that I know of to turn off these 3 red static lights on the motherboard unless I put electric tape over them. I wish ASRock would let us know about the lighting or have a feature to turn them off because it kind of negates the purpose of having RGB features (unless your preferred color is red and you want static lighting).

Some features don't work 7/3/2018 11:42:17 AM

Pros: Works fine for use without over clocking.

Cons: Although the option for wake on lan (wol) is present on the chipset, it does not work. WOL does not work with win 10. I have correctly enabled in the bios and in the windows drivers for the network card.
