ASRock X299 Taichi Motherboard Review

Packaging and Overview




Box and packaging are similar to what I have seen before from other ASRock's HEDT Taichi boards (mainly the X99 Taichi). The motherboard is well protected and zip tied into a foam tray, which is inside an anti-static bag.





The accessory package includes four SATA6Gb/s cables, two WIFI Antenna, IO shield, SLI HB bridge, 3-way SLI bridge, case badge, manuals, post card, and driver DVD.




ASRock put five fan headers on the X299 Taichi, all of them are 4-pin hybrid DC/PWM mode headers. All of them but the CPU fan header circled in red can auto detect whether a DC or PWM fan is in use. The CPU fan header supports 1A, while the two headers circled in blue over 1.5A of output. I am not sure of the current capabilities of the headers circled in green, but I would assume a minimum of 1A. The back of the motherboard has a ton of components, including the majority of the PCI-E quick switches.




The IO shield offers two USB 2.0 ports, four USB 3.0 ports, PS/2 keyboard/mouse port, WIFI antenna connectors, BIOS Flash Back button, Clear CMOS button, two 1Gbit Intel LAN ports, USB 3.1 type-A, USB 3.1 type-C, and gold plated 7.1 audio jacks with S/PDIF out.




The PCI-E lane allotment isn't straightforward, so I will list the speeds according to PCI-E slots PCIE1/PCIE2/PCIE3/PCIE5 as per the manual. With a 44 lane CPU you get x16/x8/x16/x0 or x8/x8/x16/x8, with 28 lanes you get x16/x0/x8/x0 or x8/x0/x8/x8, and with 16 lanes you get x16/x0/x0/x0 or x8/x0/x4/x0. That means that the 16 lane CPUs won't support SLI, only CrossFireX.


The three 32Gb/s M.2 slots all have one link to SATA ports 0,1, and 7, the manual will tell you which are shared. The M2_1 slot gets its bandwidth from the CPU, so with a 16 lane CPU, you will have to run your GPU at x8 if you want to use the slot. The 28 and 44 lane CPUs don't use PCI-E layout lanes if you use M2_1.




There are ten SATA6Gb/s ports, two of them are from ASMedia, and ports 0,1, and 7 share with M.2 slots if a SATA based M.2 drive is used. There is one right angled USB 3.0 header and one straight angled USB 3.0 header, both get their bandwidth from an ASMedia USB 3.0 hub.




An RGB header is located at the top right corner of the motherboard. In the lower right corner of the motherboard is a POST code display.




There are two USB 2.0 headers located along the bottom edge along with a ThunderBolt 3 GPIO header. An RGB LED header can also be found on this lower edge. The VROC header is located near the CPU socket.




The heat sinks are all screwed into the motherboard, and they seem to make solid contact.
