LGA 1151 Z370 board for 8th Gen Intel Core

The ASUS ROG Maximus X Hero uses the Intel Z370 chipset and an LGA 1151 socket limited to 8th generation Intel Core processors. It is not backward compatible with earlier LGA 1151 CPUs. The ATX layout provides dual-channel DDR4 memory across four slots with a maximum capacity of 64 GB.

Thermal design and power delivery for overclocking

Heatsinks on the voltage regulator modules and the chipset dissipate heat during sustained loads. Fan headers support PWM and DC control for precise cooling curves. The 8-pin and 4-pin CPU power connectors supply stable current for high-frequency operation. Intel I219-V LAN adds low-latency wired networking.

SupremeFX S1220 audio and M.2 flexibility

The onboard ROG SupremeFX S1220 codec delivers eight-channel high-definition audio with dedicated headphone amplification. Two M.2 sockets accept 2242, 2260 and 2280 modules; the first supports both PCIe 3.0 x4 and SATA modes while the second runs PCIe 3.0 x4. Six SATA 6 Gb/s ports provide RAID 0, 1, 5 and 10 options.

Questions about this item

How do I install an M.2 2280 drive into the M.2_1 Socket 3 with M Key, and what step is often missed?

Insert the drive at an angle into the M.2_1 slot, secure it with the supplied screw, and verify in BIOS whether the drive is running in PCIe 3.0 x4 or SATA mode, as the slot supports both and the mode affects which SATA ports remain usable.

What maintenance or replacement will the ROG SupremeFX S1220 audio codec need over time?

The S1220 codec is soldered to the board and requires no scheduled maintenance; if audio quality degrades, check for driver updates or inspect the rear-panel jacks for dust before considering a board-level repair.

Which limit appears first when the dual-channel DDR4 kit runs at 4133(O.C.) under sustained load?

The memory controller on the 8th Gen CPU and the board's power delivery set the practical ceiling; pushing 4133 MT/s continuously often hits thermal or voltage limits before the Z370 chipset itself becomes the bottleneck.
