Excellent motherboard 11/16/2018 9:54:13 AM

Pros: Running RAM in XMP level 2 (3200), and a Threadripper 1950X CPU OC'd at 3.9 GHz on all cores while solely using an active cooling solution (Noctua)! With 2x GC in Crossfire, I also have 2x SSD in RAID0 for the OS, 2xM.2 Samsung NVME in RAID0 for the applications, library files and Windows swap file, and 2x Crucial 1TB SSD in RAID0 for user's documents and production files. This board rocks!

Cons: BIOS update is touchy : the only method that works is via BIOS flashback using a max 2GB Fat32 USB stick, which must be inserted in THE sole port that's dedicated for flashback (look up the manual), and then a BIOS reset via the Clear CMOS button (above the BIOS flashback button). It took a while, and almost an RMA, to figure this out as the BIOS feature for updating itself doesn't work (more over, do NOT try this via MSI's Live Update application - which is flawed bloatware, don't use it). That's why I've removed an egg since it made me lost valuable time to figure it out - and thus money.

Not a beginner's motherboard, but has a LOT of flexibility and is very stable 9/10/2018 4:07:26 PM

Pros: has just about every option (excluding 10 gigabit ethernet) you could really want. Stable under very heavy loads

Cons: complicated setup - you best know what you're doing. Older bioses can also cause confusion (see my comment below)

Overall Review: If you're going to use a 2nd gen thread ripper, make sure to update the bios using the bios flash back method (check page 41 of the motherboard manual on how to do this). My setup (using a 2950x) did not post until I updated to the newest bios using this method. Fortunately this isn't hard to do if you read the manual

Bios... Bios... Ugh.... BIOS!!!!!!! 8/13/2018 7:05:52 PM

Pros: This board has a ton RGB led flair and the newer version of the MSI mistic light is WAY better than the transparent one. The board's hardware performance is as advertised if your trying to run a simple setup, but then again who buys these expensive boards and does that? Sorry MSI I would've given you 5 eggs but the bios you provide on this board sucks and for a board like this having shotty bios makes having this board NOT FUN AT ALL!!

Cons: If you have this board, please save yourself the trouble and DO NOT UPDATE the BIOS past 7B09v17 (2017-12-19) unless absolutely positively necessary. This board becomes extremely unstable, freezes, and is slow to boot/post after saving config in the bios or restarting. This board takes FOREVER to post when sata or nvme raid is enabled under the new bios and doesn't appear to have a cmos battery that can be removed to reset the board back to the factory bios. The clear cmos button and the JBT1 bios clear jumper only clears the settings in the last flashed bios and does not resolve the issue if you decide to re-enable raid.

Tight Layout. 4/9/2018 8:08:26 PM

Pros: Look good. So far runs great.

Cons: Dont expect to run 4 GPUs if you use a wifi card. All the pcie x1 slots are blocked by dual slot gpus. No built in wifi. They give you a 1x card!

MSI X399 PRO AMD TR4 Mainboard 2/11/2018 10:16:05 AM

Pros: Works great with AMD Ryzen Threadripper 1950X CPU running Windows 7 64-bit OS.

Great memory compatibility and stable operation with MSI version 1.7 BIOS and G.SKILL TridentZ F4-4000C18Q-32GTZ DDR4 RAM. Can use all four sticks for 32GB of quad-channel memory.

Runs cool and quiet after tuning the fans. Noctua NH-U14S-TR4-SP3 AMD TR4 CPU Cooler keeps my Threadripper at 39 degrees C during low usage, and below 61 degrees C under full load.

Wireless network card, rear shroud, and M.2 heat spreaders do not have to be installed for mainboard to work.

Cons: MSI Command Center software has a cumbersome GUI layout. The fan tuning function in MSI Command Center does not take into account fan location and airflow direction. Fans must be manually tuned in the BIOS.

No way to turn off LEDS in the BIOS. MSI Mystic Light software must be installed to turn off the LEDS.

Even though the splash screen is disabled in the BIOS, it shows up when password booting is enabled. No way to disable or customize splash screen when password booting is enabled.

Overall Review: My computer is entirely air cooled, with no water cooling. Removed rear shroud and M.2 heat spreaders to allow air to reach surface mount components on mainboard.

The build quality of the mainboard is top notch. My issues are with the BIOS and MSI's utility software, which can be fixed via updates from MSI.
