It provides four DDR5 slots for up to 256GB of memory and includes Wi-Fi 802.11 be connectivity. The edition features a Hatsune Miku theme for builders who want a coordinated look.

Who this suits and who should look elsewhere

Enthusiasts building a high-end gaming or AI workstation will benefit from the robust 16+2+1 power design rated at 80A per stage and dual ProCool II connectors. The dual PCIe 5.0 M.2 slots and dual USB4 Type-C ports give fast storage and peripheral options. Users on a tighter budget or those needing a smaller form factor should consider a different board.

What the bundled accessories and software change

ASUS AI Advisor, AI Cache Boost, AI Cooling II, AI Networking II and AEMP simplify setup and can improve performance without manual tuning. The massive heatsinks with integrated I/O cover and high-conductivity thermal pads keep the power delivery and M.2 drives cool under load. The Realtek ALC1220P codec with 7.1 channels and an internal amplifier enhances headphone and speaker audio quality.

Questions about this item

What DDR5 memory speed and capacity does the ROG STRIX X870E-H S MIKU support for the Ryzen 7 9800X3D?

The board has four 288-pin DDR5 slots running dual-channel. It supports up to 8000+ MT/s when overclocked and a maximum of 256 GB total capacity.

Will my existing PCIe 4.0 graphics card and SATA SSDs work at full speed on the X870E chipset with this CPU?

Yes. The Ryzen 7 9800X3D drives one PCIe 5.0 x16 slot and one PCIe 5.0 M.2 slot, while the chipset provides a PCIe 4.0 x16 slot at x4 mode, a second PCIe 5.0 M.2 slot, two PCIe 4.0 M.2 slots and four SATA 6 Gb/s ports for legacy drives.

How can I confirm the Wi-Fi 7 and 5 Gbps LAN are active after building the system?

In Windows Device Manager check for a Wi-Fi 802.11 be adapter and a 5 Gbps Ethernet controller. The ROG STRIX X870E-H S MIKU rear I/O includes dual USB4 Type-C ports and a USB 10 Gbps Type-C port with PD 3.0 up to 30 W for quick peripheral verification.
