The motherboard is created for extreme OC 9/18/2020 11:39:57 AM

Pros: 1- Solid performance while overclocking.
2- Beautiful design & beautiful lighting effects.

Cons: Faced a problem while installing the ram sticks. The motherboard was showing 55 code error. Then I used 16GB (dual channel), and it started to work properly. I managed to use the remaining ram sticks. I'm still not sure if the problem is with my installation process or other thing.

Overall Review: Of Course the motherboard is pricey, but after seeing the performance while overclocking, it deserve every single bucks.

Horrible Product -- STAY AWAY, DO NOT BUY ASUS. 9/16/2020 2:58:05 PM

Pros: It looks pretty!

Cons: EVERYTHING ELSE.

Overall Review: I bought my first edition of this board from Jeff Bezos, had everything installed nicely, started it up and it began my nightmare, "A2" error. Called ASUS tech support and spoke to a wonderful Indian gentleman who informed me that the motherboard must be defective, and they would be happy to RMA it and fix it and give it back or replace it entirely. As I was under Bezos's wonderful warranty program, I replaced it for a new board. I set it up, and, again, the "A2" error on the second board.

At this time, I gave it to a local tech shop and they, too, could not figure out WHAT was wrong with the setup.

Returned the second board, as well as the CPU, Memory (which is on the QVL), and the M2 (which is also on the QVL). Got entirely different CPU, same memory, same M2.

Installed everything a 3rd time. GUESS WHAT? A2 Error.

I am beyond frustrated at this point, and this will be the last PC I ever build (after 20+ years of building them, I've had enough). Just got off the phone with another wonderful Indian gentleman who informed me there are no American tech support agents, because I couldn't understand WHAT he was saying 9 times out of 10 -- just what you want to hear when you spend OVER SEVEN HUNDRED EFFIN DOLLARS ON A EFFIN MOTHERBOARD.

This is the last ASUS product I ever buy. I can't wait til Corsair starts making high end motherboards and wipes the floor with these losers. Horrible product, horrible experience, NEVER BUY ASUS.

Manufacturer Response:
Dear Christopher H.,

I'm sorry to hear that you had boot issues with multiple boards, and with ASUS Support. This is certainly not the kind of experience that we want any of our customers to have. While it is true that we do not have any call center agents in North America, there is a support team located here. Can you send me the case numbers from your earlier interactions with Support? I'd like to investigate for quality control. Regarding your boot issue, that code generally indicates that the machine is having trouble finding a boot device. Was this a brand new build, or did the drive have an existing boot file installed? I recommend using a single clean drive, with all auxiliary drives disconnected and then attempting to install boot media. Please reach out to me at cl-lane@asus.com and include case #N200957428 in your email for reference. I would be happy to help you troubleshoot in more detail.

Thank you for choosing ASUS!

Best regards,
Lane

Insane 8/18/2020 12:22:38 PM

Pros: I can only describe this board as insane.

I bought a Maximus XII Hero originally, but the VRMs had excessive coil whine in some use cases. The Extreme has slight coil whine in those use cases, but not nearly as bad.

Cons: The price of this board is equally insane. Motherboards shouldn't cost more than the CPUs. It would be nice if there were more side RGB strip LEDs to make the strip appear more seamless.

Overall Review: If you're looking for a top-tier motherboard, this is it; but, there are much cheaper solutions out there.
