Terrible setup... CMOS rev issue. 8/15/2020 11:55:36 AM

Cons: I bought this with a Rizen 3 3600 due to it supposedly being Rizen 3 ready. It is not. In fact, its not even Rizen 2 ready. I pulled a known working Rizen 2 2600 out of another machine, installed it and it still wont post. That is the same behavior it was showing with the Rizen 3 chip.

I can only assume that the BIOS was never updated on this board. Im not sure what to do now. All other indicators on the MB are good. Everything powers up and all fans spin. I just cant get the machine to post, even in the most basic of hardware configurations: MB, CPU and RAM.

Pretty disappointing. Ive used ASUS for years but they missed the mark on this board.

Overall Review: Disappointed.

Dear Edward F.,

I'm sorry to hear that you are having issues with this board. This is certainly not the kind of experience that we want any of our customers to have. While it is true that the BIOS may not be flashed for the Ryzen 5 3600, this board supports the Ryzen 5 2600 with the factory BIOS. Since you are not booting with either, this is not a BIOS issue. What graphics card are you using with this system? Can you send me your complete system specifications so that I can help you troubleshoot this in more detail? Please reach out to me at cl-lane@asus.com and include case #N200853375 in your email for reference.

​Thank you for choosing ASUS!

Dead Motherboard 8/15/2020 2:22:59 AM

Pros: Worked for about 30 days

Cons: I built my first pc with this motherboard. At first, booting it up was a very difficult process. Some USB ports were not working and no display on monitors. Had to unplug everything and plug it back in and it finally posted. But while I game my PC shuts off. At first I thought it was a PSU or a GPU issue. So i tried replacing it but it did not make a difference. I even tried switching the ram around, but didn't work. After further investigation, I came to a conclusion that there was a lack of voltage or power being send through my motherboard. It even causes me to not even be able to reset my PC. I am very disappointed and upset considering this was my first build. ASUS if there is anyway please contact me@damienkim08@gmail.com

Overall Review: I would recommend it. But I guess I got very unlucky :(

Dear Valued Customer,

I'm sorry to hear that you are having various issues with this motherboard. All ASUS products undergo intensive quality control, testing and inspections. What you've experienced was not intentional or representative of our brand. I have sent you an email as requested, but based on your description it seems likely that there is a short in your case. If this is indeed a power issue and the replacement power supply did not resolve it, we would be happy to repair the board in warranty for you. Please reach out to me at cl-lane@asus.com and include case #N200853488 in your email for reference.

​Thank you for choosing ASUS!
