Manufacturer Response:
Dear Michael,

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.
• Clear the CMOS.
• Test with 1 x memory module (any slot), switching another memory and slot if its same issue.
• Reseat video card firmly and 6+6 PCIE power (if applied).
• Connect the monitor.
• Plug the 24 + 8 or 4 pins ATX power.
• Connect the chassis power switch to mainboard.
• Turn on the power (using onboard power button) to check if its post.

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

Died slowly but in under 1 year 11/12/2019 11:11:14 AM

Pros: It’s pretty

Cons: Chased issues around this board for months. DR DEBUG, while seeming convenient, led me on an error hunt for several months casting doubt on just about every other component in the case. Once I had verified the functionality of literally everything else, the board finally crapped out entirely and will not boot despite reseating everything, starting from scratch with minimal components, and following every suggestion offered through the ASROCK website. I have contacted support and not even received an automated email. As a hobbyist my time is limited and this has taken place over several months with brief periods of functionality. I wish it had been more obvious to me sooner since every other one of my components when tested in another machine turned out to be fine. I recommend spending the extra money to buy a TR4 board from a different manufacturer. At this point, while I would take a replacement, I would likely just sell it to buy a more reputable motherboard.

Should have listened to the horror stories. 11/8/2019 1:33:05 PM

Pros: None.

Cons: Does not meet any acceptable standard of quality assurance.

Overall Review: This defective garbage worked for 18 hours, then shut down and won't power back up. Tried three different PSU's, and this board is dead. I'm waiting for a new board to arrive so I can find out if it destroyed a 2nd gen Threadripper or not.

ASRock is the computer parts equivalent of "Great Value" at big box stores. I should have listened to my gut and not purchased from them.

Please read before purchasing -- Great until mysteriously dead 9/29/2019 12:21:54 PM

Pros: Worked well and I was happy with features + build quality for all 2 months that it was working.

Cons: I would suggest that you Google search "ASRock x399 Taichi board not posting" and read some of the more detailed stories that users have posted regarding the board not posting. They are very consistent in the way that they have presented the details and the issues are practically undiagnosable.

My board completely stopped working after about 2 months and I tried everything under the sun including:
-ASRock's recommended debugging procedure posted on users's reviews here.
-Starting with basically no hardware whatsoever and progressively building up
-BIOS Flashback
-Reseating processor (no bent pins, processor looks pristine)
-Buying a newer, higher wattage PSU to verify it wasn't power-related
-Checking PSU to MOBO / GPU power connections upwards of 100 times throughout the entire debugging process.

I couldn't get the board to post with a processor and 1 stick of ram, I couldn't get it to output any video feed, I couldn't get it to do anything other than the LED pulsing when power was connected.

Overall Review: I purchased this board due to a good history with ASRock (8+ years using their boards) for my 2950x work build. I spent upwards of 9 hours continuously trying to debug leveraging the collective minds of a combined 40 years of PC building without any success. I will begin RMA process soon, but I would strongly suggest that you do not purchase this board.

I lost more than a day worth of crucial work in addition to other issues stemming from this. I recently purchased the Gigabyte Aorus Pro X399 and of course everything installed and it posted first try.

Please avoid this board and the potential nightmare of undiagnosable failure that seems to plague this model. I'm no longer an ASRock customer because of it.

A good board 9/22/2019 8:42:18 AM

Pros: Decent arrangement of pins and PSU connectors.

Updating the BiOS is easy enough (but be certain to do that.

Works well with my TR 2950x

Cons: Spacing for the RAM slots closest to the CPU is very tight if you're using an AIO.

Some cable locations can be a tight fit, depending on your case.

Could use more USB connectors.

Could use a USB Type C for cases which support it.

Overall Review: I definitely recommend this MoBo. But be aware of the memory you purchase, especially if it's RGB as the spacing is tight when used with an AIO.

Great Motherboard for the price 8/11/2019 7:49:32 AM

Pros: Works very well with Threadripper 2950. Gskill 3600 memory set in XMP. Samsung Nvme 970 pro. Windows Pro 10 latest update.
Lots of Bios settings to use.
Built in Wifi works well.
Customer support is great. Had issue with RGB app & they sent me the Flash instructions.

Thanks ASRock crew.

Cons: RGB app needs to be flashed to work. You can get the flash instructions from ASRock website.
Board markings non existant or very faint. You will have to use manual to install memory
and case wires correctly.

Overall Review: First ASRock motherboard. Great price plus rebate from Newegg. I don't overclock so I don't know if the board is stable in OC mode.
Overall very happy with this purchase.
