Intel Z270 / LGA1151 ATX ROG board with DDR4, three PCIe x16-length slots and dual M.2. This is a dedicated model record; revision, CPU and firmware qualifications are documented below.
IDENTIFICATION: Verify the printed model and PCB revision against manufacturer support files before selecting a processor, memory kit, firmware image or replacement board. Similar names can describe electrically different products.
Specifications
| Catalog subcategory | Enthusiast Intel platforms |
|---|---|
| Exact board / revision | Maximus IX Hero |
| Platform / era | Intel Kaby Lake / Skylake enthusiast desktop platform, 2017 |
| CPU socket / compatibility | LGA1151; 7th- and 6th-generation Intel Core processors as listed by ASUS for this board and installed BIOS. Socket fit is not proof of compatibility with other LGA1151 generations. |
| Chipset | Intel Z270 Express |
| Memory | Four dual-channel DDR4 DIMM sockets, up to 64 GB non-ECC unbuffered memory; XMP and overclocked transfer rates depend on CPU, BIOS and validated modules. |
| Expansion slots | Three PCIe 3.0 x16-length slots; two are processor-connected and lane-shared, while the third is chipset-connected up to x4; three PCIe 3.0 x1 slots. |
| Form factor | ATX, approximately 305 × 244 mm; confirm case/standoff support and PCB dimensions in the manufacturer manual. |
| Storage / I/O | Six SATA 6 Gb/s ports and two M.2 sockets (PCIe/SATA modes vary by socket/device); consult ASUS’s manual for simultaneous-use limits and connector sharing. |
| Firmware and validation | Use only firmware for this exact model and revision. Confirm the selected CPU in the manufacturer CPU support table and satisfy its stated minimum BIOS; consult the board manual and memory QVL for DIMM placement, shared lanes and port limitations. |
Compatibility and revision notes
ATX (305 × 244 mm). The Maximus IX Hero is a 200-series platform; do not infer compatibility from the same LGA1151 socket on later Intel chipsets. Confirm the model-specific CPU support list, BIOS version, DDR4 population rules and M.2/SATA resource sharing in ASUS documentation.
Physical socket fit, chipset family or a matching module notch does not independently guarantee compatibility. Confirm the exact CPU, BIOS release, memory type/capacity, slot wiring, device protocol and board dimensions in the manufacturer documentation before building or servicing a system.
Preservation and repair
Record the full PCB model, revision and BIOS identifier before maintenance. Inspect socket contacts, DIMM/PCIe connectors, VRM area and electrolytic components; document any corrosion, rework or missing hardware. Use ESD-safe handling and follow the manual’s clear-CMOS procedure.
For an archive record, photograph labels and connector condition before cleaning. Do not cross-flash firmware from a similar model or revision, and never power a board with loose conductive hardware beneath it.
