ASUS ROG Crosshair VIII Formula
AMD X570 Socket AM4 2019 enthusiast desktop board. This static record describes this exact model and revision only; confirm the printed PCB identity and use the cited manufacturer's support files.
REVISION / FIRMWARE WARNING: Similar model names, PCB revisions and regional SKUs may differ in connectors, radio hardware and firmware. Identify the exact board printed on the PCB before selecting a BIOS.
Specifications
| Exact model / generation | ASUS ROG Crosshair VIII Formula — 2019 enthusiast desktop board |
|---|---|
| Chipset | AMD X570 |
| CPU socket / support | Socket AM4; processor families and minimum BIOS are limited to the exact manufacturer CPU support list. |
| Form factor | ATX, 305 × 244 mm |
| Memory support | Four dual-channel DDR4 DIMM slots; up to 128 GB. Supported rates depend on CPU, BIOS and the ASUS QVL; ECC mode depends on CPU. |
| PCI Express expansion | Three x16-length slots and one x1 slot: the two primary CPU-connected slots support PCIe 4.0 with Ryzen 3000/5000 processors and operate x16 or x8/x8; the chipset-connected x16 slot is x4. Consult the manual lane table. |
| Storage | Two M-key M.2 sockets (PCIe 4.0/3.0 x4; one also accepts SATA M.2) and eight SATA 6 Gb/s ports; RAID and sharing rules are firmware/manual-specific. |
| Rear I/O and network | Rear USB 3.2 Gen 2 Type-A and Type-C plus USB 3.2/2.0 ports; HDMI output, optical audio, two RJ-45 LAN ports, Wi-Fi antenna connectors and BIOS FlashBack. Wired networking is 5GbE plus Gigabit; onboard Wi-Fi 6 / Bluetooth 5.0. |
| BIOS / manufacturer support | UEFI firmware with USB BIOS FlashBack and model-specific CPU support/BIOS downloads. Match the exact processor, minimum BIOS and manual to the board; do not use firmware for the Crosshair VIII Hero or another Formula variant. |
Compatibility and installation notes
AM4 is not a guarantee that every AM4 CPU is supported: ASUS lists processor support and minimum BIOS per model. DDR4 only. PCIe generation follows CPU capability; verify the x16 bifurcation, M.2/SATA sharing, memory QVL and required EPS power in the manual.
Before assembly, confirm board revision, chassis dimensions/standoffs, CPU cooler mount and power leads in the manual. Never infer processor compatibility from the physical socket alone. For memory, follow the documented population order and consult the exact board's QVL; EXPO/XMP and other overclocked speeds are not guaranteed.
Read the lane-sharing tables before installing expansion cards and drives. Observe ESD precautions, protect socket contacts, and record the installed BIOS revision and any update history.
Preservation and service
Inspect the socket, DIMM slots, power connectors, M.2 thermal hardware and capacitors before use. Record PCB revision and serial/date codes, document repairs and test conditions, and retain model-matched manual and firmware files. Do not cross-flash firmware from a similarly named board.
