Which Intel processor generations does the Z790I Lightning WiFi support?
The board supports 12th, 13th, and 14th Gen Intel Core processors on the LGA1700 socket. All three generations share the same physical socket, so a 12th-Gen system can be upgraded to a 14th-Gen CPU without a board swap, provided BIOS is up to date.
What does the 14+1+1 phase power design mean for overclocking headroom?
The 14+1+1 configuration with 110A Smart Power Stages on VCore and GT means each phase carries a high current budget, which reduces thermal stress per stage under sustained load. For a Mini-ITX board, this is an unusually robust VRM — it provides meaningful headroom for running a 13th or 14th-Gen K-series CPU at elevated power limits without voltage instability or thermal throttling from the delivery circuit.
Will this board bottleneck a PCIe 5.0 NVMe drive or GPU?
No. The single PCIe 5.0 x16 slot runs at full gen5 bandwidth for a GPU, and the two Hyper M.2 slots are PCIe Gen4 x4 — which tops out around 7,000 MB/s per slot. At the time of this board's release, Gen4 x4 is not a storage bottleneck for any consumer workload.
How much RAM can this board actually support, and what speed is realistic?
Two DDR5 DIMM slots support up to 96GB total (two 48GB sticks). XMP/EXPO profiles are supported up to DDR5-8600, though real-world stability at that speed depends on the memory kit's ICs. DDR5-6000 to DDR5-6400 represents the sweet spot for performance-per-dollar on this platform.
Does the Wi-Fi 6E antenna need to be installed externally?
Yes. The 802.11axe (Wi-Fi 6E) module uses external antenna connectors on the rear I/O. The antenna(s) must be connected for full signal strength; operating without them in a metal case will degrade wireless performance significantly.
