The Gigabyte Z890 UD motherboard adds rear USB4 Type-C, 2.5Gbps LAN, Wi-Fi 6E and Bluetooth 5.3 plus mid-board USB Type-C headers. A Thermaltake Toughpower 1200W 80 PLUS Gold unit supplies power with Japanese capacitors and a 140mm fan.

Storage and Software Ready

A 1TB Samsung 990 PRO PCIe 4.0x4 NVMe drive delivers up to 7450 MB/s reads and 6900 MB/s writes alongside a 10TB HDD with 256MB cache. Four M.2 slots and four SATA 6Gb/s ports supporting RAID 0, 1, 5, 10 allow further expansion. Realtek 7.1 surround audio and the pre-loaded Windows 11 Pro 64-bit complete the package.

The Corsair 4000D chassis fits a 360 mm radiator up front and includes two 3.5-inch bays for the 10 TB drive plus two 2.5-inch bays for additional SSDs.

Which BIOS setting must be enabled so the Samsung 990 PRO SSD runs at its full PCIe 4.0 x4 speed?

Enter the Gigabyte Z890 UD BIOS, set the M.2 slot to PCIe 4.0 x4 instead of Auto, and confirm the drive appears at Gen 4 speeds before installing Windows 11 Pro.
