So glad I waited to buy the parts for my build. The Skylake X cpus are power hungry, and they're known to run rather hot. Then when you watch this...


...and know board manufacturers were rushing the x299 boards out the door, you could understand why there would be problems.

Voila! In November, ASRock released this Extreme4 Board for $190 USD. It has a VRM heat pipe and dual 8 CPU connectors. These were two features I was really looking for when I was considering my x299 MOB.

Oddly enough, there were only a handful of x299 boards that had both. The Taichi XE (a new updated Taichi release) for $315 USD and the Gigabyte Aorus 7 for $400 USD. I didn't feel like spending that much on my board, as I did try to stay within a $2,000 USD budget.

This board is rock solid, the BIOS for a Windows user newb is easy to use and navigate. It's easy for overclocking. I have my 7820x running at 4.5GHz.

I wish this board had three NVMe M.2 slots, but I can easily live with two.

It has plenty of fan headers for me - I'm running with 4 case fans and two radiator fans.

I like the board has subdued RBG lighting. It's just enough to keep it interesting.

I don't need Wifi, so wasn't worried about the board having built in Wifi.

Plenty of USB 3 ports for me, as I won't be using all the ports at all.

Will give an update in another 6 months, or if something comes up before. As of right now, it's running rock solid.

Crazy good value for $190, IMO.

Edit (09/04/18): 6+ month update: This motherboard is singing along with zero issues. I've since built another photo/video editing workstation with this same motherboard and 7820x CPU. If you're planning an x299 build, I highly recommend this board.
