Very buggy 2/10/2019 4:56:46 PM

Pros: Plenty of expansion slots, looks very sleek, can easily overclock my 7920x to 4.5ghz

Cons: Board is a little buggy, at ,least in terms of the expansion slots and peripheral cards, especially sound cards. I tried two separate Asus sound cards and I get an error 10 in device manager on both, even after disabling onboard sound. I was able to get a Creative Labs sound card to work but only in the 6th pcie slot. If I put it in any other slot, it clashes with my Areca RAID card and I cannot boot. I have none of these problems in my other x299 Extreme RIG board. I am sure a BIOS update will fix it, but very disappointing that this wasn't caught in their QA labs.

Manufacturer Response:
Dear Valued Customer,

Thank you for your review. I'm sorry to hear that you are having compatibility issues with PCIe expansion cards with your motherboard, that certainly sounds like a frustrating issue. Please make sure that the drivers on your sound cards are updated. You can also update the motherboard BIOS and audio drivers to the most recent versions here If none of these suggestions work for you, please reach out to me at I would like to help you resolve this issue completely. Please include case #N190803441 in your email for reference.

Thank you for choosing ASUS!

Best regards,

Great motherboard 2/6/2019 12:11:47 PM

Pros: Good VRM heatsink keeps cool and also comes with a small 40 mm fan just in case. Was able to overclock my i9 7940x@4700 mhz. Also comes with 2 PLX switches to run 1,3,5,7 at x16 and if you use all 7 slots at x8. 2 Eight pin connectors for cpu and a 6 pin connector for power to the PLX switches. 8 true power phases for overclocking HCC cpu. On board audio sounds great. The 2 m.2 slots cannot run in raid due to one runs on cpu lanes and the other on the pch. The m.2 near the cpu can run raid with the u.2 slots on the motherboard. AI suite works okay but I uninstalled.

update 02/06/2019:
Cpu is still running great was able to overclock 100 mhz more to 4800 mhz on cpu. But because of summer temps are a warmer and had to increase voltage to 1.30. If I stress all cores temp hit 95 C. I am now able to run my ram at 3466 mhz. Also new bios from ASUS 0905 is out.

Cons: none running motherboard for over a month with no problems so far.

Great mixed-use board - Gaming, editing, VM's, etc. 1/14/2019 11:32:54 AM

Pros: 7 PCI-e lanes
7 PCI-e lanes
Now officially supports the 9th gen i7 and i9 lines.
Supports up to 128gb RAM
Fairly well designed board with great overclocking ability
Nice classy subdued look to it and not like many of Asus boards that are in your face.
It is great board for those who want to game, edit videos, run multiple VM's, GPGPU simulations, etc.
Inputs for plenty of power for CPU and video cards. It utilizes two 8 pin CPU connectors and down near the PCI-e slot 1 there is a 6 pin PCI-e connector.

Cons: The main problem I have with the board is that it will NOT run the processor at stock frequency. I realize no one buys an expensive Intel x processor without overclocking it, but I always like to get baseline from all new machines. Then, I incrementally bump and test, bump and test. This one, correctly detects my i9-9980X but it won't run it at 3.0ghz but instead 3.8ghz, even in the BIOS. Then, it often bumps it beyond that once in Windows. The additional bump may be due to Intel's Turbo Boost 3.0. Regardless, I should have to initiate the overclocking on my board. I have even cleared the CMOS, reset all my custom settings, etc.
Some of the fan headers are at weird places. One of the chassis fan header is in line with PCI-e #1, directly underneath the GPU. As a result, it would have to be extremely bent over to try to use it.
One M.2 slot can get restricted air flow depending on GPU arrangement. The other one stands up vertically in the way.
No USB 2.0 slots (for front USB ports or more importantly for AIO pumps). I wish they'd take off the RGB headers and give us one of them instead.
PLX chips run quite hot
Initially it appeared the bright red 'boot code display' on the bottom of the motherboard could not be turned off. I don't know if it truly wasn't there, or if I just didn't find it. However, when setting it all back up after installing the latest 905 update, there is now an option to turn it off once it has finished booting.

Overall Review: I wish they would have put connectors in a little different spot, especially the fan header that is inline with PCI-e slot 1.

The advertisement on their website mentions all the temperature sensors and how you can use that to control your fan speed but I haven't found much as to which sensor(s) control which fan(s).

The system is:
Asus WS x299 Sage
Intel i9-9980x
128gb of GSkill DDR-4
Samsung 2TB NVMe M.2 drive
Two EVGA 2080ti's with Asus NVLink between them
Antec HCP-1000 power supply.
Asus BD-RW
Fractal Design - Define R6 Blackout case (very well designed case)
