does mostly ok

Pros: easy set up

Cons: Problems running dual channel. The memory listed was supported, but I could only get a single channel. Running 16 gigs as single channel isn't really that big a deal. Just wish it did better in that area

Manufacturer Response:
Dear Harold,

We sincerely apologize for any inconvenience this may have caused you.
Please trouble shoot the mainboard whether the issue is resolved.
• Unplug the ATX power, remove all components from mainboard.
• Clear the CMOS.
• Check the mainboard’s CPU contact pins are normal (should be pointing same way and pattern). Please see attached for sample image.
• Reseat the CPU and heatsink fan if socket pins are normal.
• Test with single memory module on each slot one at the time to verify all slots are working individually.
• Populate the memory one by one if the memory and slots are working individually.

If you have any technical support inquiry, please contact us at http://event.asrock.com/tsd.asp
We will assist you shortly.

Thank you

no sli

Pros: easy installation
works

Cons: bios is not intuitive for overclocking.

does not support SLI. I bought this board to upgrade a friend out of an alienware build only to find out that this board only supports AMD crossfire which doesn't help when you have 2 1080 it's. Nowhere on the item page does it mention SLI/Crossfire only that the PCIe lanes run at 16x and 4x when both are populated.

Will probably return and buy a different board.

really disappointed in asrock for this as well as newegg to a certain extent.

Manufacturer Response:
Dear Valued ASRock Customer,

Thank you for purchase and review.
Unfortunately, the board does not support SLI configuration.
The SLI required PCIE 8x mode.
Please visit link below under slots section to check.

Dishonest rebate, be warned!

Pros: Decent quality for its price range.

Cons: Can get a better motherboard for around the same price without the rebate.

Other Thoughts: ASrock seem like a very dishonest company when it comes to rebates. It seems like they simply use the promise of large rebates to get people to buy their product, without customers realizing that they are very unlikely to actually get it.

They have the ABSURD requirement that you must send your rebate request in, within 10 calendar days of your INVOICE, rather than your package arrival. I have NEVER seen this before and I have done a few main in rebates in the past. If your package doesn't arrive before 10 days, you can't send in a rebate.

Their website is also a mess when registering your rebate order. I unfortunately registered, but did not print the form page immediately, and instead bookmarked the page thinking I could come back the next day and print it. To my surprise, the page I bookmarked was just an empty form.

I could just print and fill the form, but I am missing some information, such as the "submission time" and "confirmation code" which I cannot get now, since you get register a second time, and despite requiring my email address, they don't send you any emails with this information.

So, I am out of luck and have no way to send in this rebate, and I feel completely cheated out of 40 dollars, even if it might be my "fault".

Very dissapointed, don't think I will ever buy an ASrock product again after seeing how deceitful they are with their rebates. I really recommend just getting a better motherboard for around the same cost.

Chipset Heatsink Too Big, Therefore Blocks Installation of Larger Graphics Cards

Pros: Supports Intel 9th Generation LGA1151 Socket CPUs

Cons: Chipset heatsink is too high (and placed in a poorly chosen location) and therefore it prevents a full seating into the PCI-Express x16 slot for the MSI Geforce RTX 2070 Duke graphics card. I've never heard of a chipset heatsink blocking the installation of a graphics card! It still works but you can see 1.5 mm of the gold (or it could be copper) plating of the PCI Express connector terminal of the card.

Excellent

Pros: 1. Works with the newest 9th generation of Intel processors.
2. In general, everything is quite high quality.

Cons: Not found

Other Thoughts: A week of operation did not reveal a single glitch.
Download Win10 about 5-7 seconds, shutdown 3-5 seconds.

Great Budget Z390 Board

Pros: Worked right out of the box with no problems. Very Nice Bios & I was able to update the bios on The ASRock website Without a single problem. Only took 5 mins from start of download to rebooting with the Updated Bios. ASRock is the 3rd Largest Motherboard manufacturer in the world, And they do a good job of it.

Cons: Motherboard had a warp in it But after screwing it down was totally fine. Really needs a larger heatsink over the VRM's. I did not take any eggs off for these, as this is the Budget Z390 board & one cannot expect it to be as good as ASRock's top of the line board considering it cost's only $100 on sale. Overall so far I am quite Pleased.

Other Thoughts: I have only used Asus, Gigabyte & MSI boards in the Past. This is my 1st ASRock Board & so far I am Happy with it.

Great budget board

Pros: For the price works well, I have it paired with a 9600k so no power issues. I have the 9600k at 5 GHz with this board. Also applies the XMP profile with no issues.

Cons: ASRock BIOs is a little tricky to navigate but not bad once you're used to it.

Other Thoughts: With a 9700k or 9900k and overclocking you may need a more expensive board to handle the power requirements.
The mATX version may be better for you if you want the option of using smaller cases
