Very disappointed after only 13 months 1/30/2020 2:34:48 PM

Pros: Worked well when it was functioning.

Cons: This motherboard lasted exactly 13 months, and then one day my pc blue screened and I could not get it started again. I researched all the symptoms and error codes I was getting, and everyone that was experiencing the same had to RMA the board. I contacted Asus support for assistance but the person I spoke with was not very knowledgeable, there was very little troubleshooting done. In the end they asked for me to send the motherboard in for RMA. I sent it in and went through the whole process. When I finally received the board and went through the long process of putting together my custom loop again, I find that nothing was fixed and I had the exact same issue. I purposefully purchased their top of the line water cooling motherboard and as such expected to receive a great product with the support to back it up, unfortunately none of that occurred. Very disappointed and with nowhere to turn.

Overall Review: Have owned several asus motherboards and other products they make, unfortunately this one did not live up, left very disappointed.

Dear Alexander S,

It's heartbreaking to hear you're not satisfied with your motherboard. What are the symptoms you've encountered with your system? Was there any Q-code displayed on your motherboard? Try taking the motherboard out of the case and set it on an insulated surface. Install JUST the CPU/cooler, and 1 stick of memory in the first slot. Plugin the 2 PSU cables to the MB. Connect the motherboard, and connect the monitor to the integrated video if it has it. Turn on the PSU. Momentarily short the 2 pins that the case's power button wires would connect to for starting. (You can also drag the case close enough to use the button's wires if you wish). If the issues persist, feel free to contact me if you have any technical or general questions. You can reach me at cl-adrian@asus.com. Your case for reference is N2001101931.

Thank you for choosing ASUS!

Best Regards,
Adrian

It's regrettable to hear you've encountered memory issues with your motherboard. Are you using XMP? Make sure you have the latest BIOS for optimal compatibility. Ensure that you have RAMs that are certified on our ASUS QVL*. You made need to change the timing on your RAMs for improved stability. If the issues persist, feel free to contact me if you have any technical or general questions. You can reach me at cl-adrian@asus.com. Your case for reference is N200189045.

Great MOBO ! 12/28/2019 9:33:09 AM

Pros: Installation was a doddle. I used the Intel Extreme Tower Heatsink Gaming Cooler for i9-9900K, to keep the i9-9900K CPU cool and added 32Gb of 4400MHz DDR4 RAM. The BIOS is fantastic and allows you to set everything. I've over-clocked the memory and it still hasn't gone above 30C. (I'm not over-clocking the CPU - I'm not a gamer) This is the best mobo I've owned in a long time and I'm really glad I made the investment.

Cons: None that I can see.

Overall Review: I would recommend this to anybody who is a DIY computer builder.

D.O.A. 11/22/2019 10:58:36 AM

Pros: This would be an awesome board if it worked.

Cons: Got error code 00 right from the get go. Tried and tested every component still got error code 00. My only deduction is that the MB is bad.

Overall Review: DOA!

Truly amazing! 10/2/2019 5:54:24 PM

Pros: Best board Iv ever owned, not even comparable. CPU at 4.6,5.0 in turbo, ram running at 4133mhz, the board itself is liquid cooled. Truly amazing tec., I highly recommend!

Cons: Needs a huge psu, to power 3 cards in sli, but well worth it in end. The only con I can think is the price, but again considering what you end up with, well worth every penny.
