Analyzing Z370 for Intel's 8th Generation Coffee Lake: A Quick Look at 50+ Motherboards

Another board currently in MSI’s Enthusiast Gaming lineup is the Z370 Gaming M5. Outside of size, the Gaming M5 is ATX versus the Godlike at E-ATX.
The overall theme on the board is a black PCB with a few grey highlights of components mixed in. The top half of the board should look pretty familiar when comparing the Gaming M5 to the Godlike Gaming flagship. While the shape of the shroud and VRM heatsinks are the same, the RGB LEDs inside on the Godlike were removed. It still carries over the fortified memory slots but loses some fan header connectivity as well as losing other RGB LEDs in that area. The PCIe area has a shroud between the slots and covers the audio portion of the board but it is not an extension of the back panel IO shroud. The PCH heatsink loses the GPU stand but keeps the same shape and RGB LEDs. Additional RGB strip support can be found through the RGB connector on the bottom of the board.
The four memory slots supports up to 64 GB in dual channel mode, with a supported speed up to DDR4-4000. There are a total of three full-length PCIe slots, the first two from the CPU using reinforced slots while the third is from the chipset. This allows for running in x16/x0/x4 or x8/x8/x4 configurations, and supports 3-way AMD Crossfire and 2-way NVIDIA SLI. Between the full-length slots are three x1 slots, getting their bandwidth from the chipset.
The board has the usual complement of six SATA ports all located on the right side of the board next to the chipset heatsink. As a side note, SATA 1/5 will be unavailable when an M.2 SATA SSD module has been installed in the first M.2 slot, while SATA 5/6 will be unavailable when an M.2 SATA SSD is used in the second M.2 slot. RAID 0, 1, 5, and 10 are supported for all SATA devices. A total of six 4-pin fan headers are found in various locations throughout the board: four system fans, one water pump, and one CPU fan connector. The audio is handled by the latest Realtek ALC1220 codec along with Chemicon audio caps and the familiar audio separation line running splitting the audio section from the rest of the board, minimizing interference. A single Rivet Networks Killer E2500 gigabit Ethernet controller is found on the Gaming M5. The power, reset, and Game Boost knob are gone, however, a debug LED can still be found on the bottom of the board.
USB 3.1 (10 Gbps) is handled by the ASMedia 3142 controller and gives the board a Type-C and a Type-A port on the back panel IO. The chipset handles six USB 3.1 (5 Gbps) ports with two Type-A on the back panel and four more through internal USB connectors. There are three USB 2.0 ports on the back panel also, and four more through internal USB headers. The back panel also has a combination PS/2 connector, a CMOS reset button, DisplayPort and HDMI video outputs, the E2500 network port, and the audio stack with SPDIF.

It seems that the PCB which holds the silicon has changed between the 7th and the 8th gen. So they most likely needed to validate the CPU. The fact that they did not move the notch means they just did not want to (could not) introduce a new socket. Either because there were so many of the old ones, or there was no time, or they did not want to push the cost to MB manufacturers to revalidate the new sockets.shabby - Friday, October 20, 2017 - link
For a split second i thought finally some x370 goodness... but no.Shame, shame, shame!

I'm waiting for actual non clown disco BS Threadripper motherboards :(ikjadoon - Friday, October 20, 2017 - link
Amazingly well done. Excellent write-up.AbRASiON - Friday, October 20, 2017 - link
Stupid question, I got the AsRock simple ITX board and it won't turbo my CPU at all (8400) like no turbo PERIOD. It never ever goes over 2763mhz?Anyone got any ideas on this? Am I just stupid and this is normal behaviour or what?

FYI: GIGABYTE Z370N-WiFi is also HDMI 2.0 capableByte - Friday, October 20, 2017 - link
If nothing else, Asus makes some damn good looking boards.docbones - Friday, October 20, 2017 - link
My big question still on the z370 is whats the 390 going to bring? Will the 370 not support a octocore chip?shabby - Friday, October 20, 2017 - link
This is intel we're talking aboot, new chip = new mobo period.Ro_Ja - Saturday, October 21, 2017 - link
Once Kaby Lake E is released, that's a new mobo again.
