## Long description

Phantom Gaming motherboard is developed for gamers seeking high performance and stability. It features a 10+1+1 power phase VRM with SPS (Smart Power Stage) Dr.MOS design, Hi-Density power connectors and an 8-layer PCB to ensure stable power delivery and support for aggressive DDR5 overclocking with XMP/EXPO profiles. Storage options include a PCIe Gen5 M.2 slot for next-generation SSDs and Hyper M.2 Gen4 x4 support. Connectivity covers Wi‑Fi 6E, Phantom Gaming 2.5 Gb/s LAN, abundant USB including front USB 3.2 Gen1 Type‑C header and USB Alternate Mode, while Nahimic audio provides enhanced sound processing and voice clarity. The board also offers onboard and addressable RGB headers with Polychrome RGB and SignalRGB support, reinforced PCIe 5.0 steel slot, and user-friendly features like EZ BIOS Flash and an adjustable I/O shield.
Advantages
The board’s optimized VRM with SPS and Hi-Density connectors delivers smooth, reliable power and improved overclocking headroom. An 8-layer PCB improves signal integrity and thermal performance for memory overclocking. Advanced storage support includes PCIe 5.0 M.2 for up to 128 Gb/s and PCIe 4.0 M.2 for high-speed SSDs. Cooling is enhanced by aluminum heatsinks, PWM/DC fan auto-detection, thermistor header and Fan‑Tastic Tuning for tailored fan curves. Networking is strengthened by Wi‑Fi 6E and a 2.5 Gb/s LAN controller, while multiple low-latency USB ports and Lightning Gaming Ports reduce input jitter. Integrated Nahimic audio and extensive RGB control complete the feature set for a balanced gaming platform.

How to use
Install the motherboard into a compatible ATX chassis, secure the adjustable I/O shield and connect the Hi‑Density CPU and main ATX power connectors. Populate DDR5 modules that support Intel XMP or AMD EXPO if you plan to enable pretested overclocking profiles. Mount M.2 SSDs into the designated PCIe Gen5 or Gen4 slots and connect front panel Type‑C and other USB headers as required. Configure cooling by connecting fans to the PWM/DC headers and, if needed, attach a thermistor cable to monitor custom zones. Use Fan‑Tastic Tuning in UEFI or the ASRock utility to set fan curves. Connect network and Wi‑Fi antennas, install drivers (LAN driver may be preinstalled), and update BIOS using EZ BIOS Flash if necessary.
Recommendations
For reliable overclocking and long-term stability, use high‑quality power supply units rated for the increased current, certified DDR5 memory modules with XMP/EXPO support, and ensure adequate case airflow. When installing heavy graphics cards, secure the reinforced steel PCIe slot and verify the chassis can accommodate the card size.
