Z490 Chipset for 10th Gen Intel Core

The ASRock Z490 Phantom Gaming 4 uses the Intel Z490 chipset and LGA 1200 socket to support 10th Generation Intel Core processors. Four DDR4 slots accept up to 128 GB of non-ECC memory with a wide range of validated speeds. Dual-channel architecture and Turbo Boost Technology 3.0 are supported.

PCIe Layout and Storage Options

Two PCI Express 3.0 x16 slots run at x16 or x16 and x4 when both are populated. Three PCI Express 3.0 x1 slots add expansion room. One Ultra M.2 socket takes 2260, 2280 or 22110 modules with PCIe Gen3 x4 or SATA 6.0 Gb/s signalling. A second M.2 Key E socket accepts 2230 Wi-Fi/BT modules with Intel CNVi. Six SATA3 ports support RAID 0, 1, 5 and 10 via Intel Rapid Storage Technology 17.

Realtek ALC1200 7.1 Audio

The onboard Realtek ALC1200 codec delivers 7.1-channel audio for gaming and media. Integrated Intel UHD Graphics outputs function only with processors that include integrated graphics. Hardware-accelerated decode covers AVC/H.264, HEVC/H.265 8-bit and 10-bit, VP8 and VP9. Intel Optane Technology is supported for compatible modules.

Questions about this item

Which Intel processor must I already have for the LGA 1200 socket on this Z490 board?

A 10th Gen Intel Core processor with an integrated GPU is required if you plan to use the onboard VGA output; the socket itself accepts any 10th Gen Core CPU.

Will my existing DDR4 3200 modules run at their rated speed alongside the board's higher OC profiles?

Yes, DDR4 3200 is listed as a supported non‑OC speed, so installed modules will operate at 3200 MT/s without manual overclocking.

How can I confirm the M.2 SSD is running at PCIe 3.0 x4 after installation?

In the BIOS advanced storage screen the M2_2 slot should show a PCIe 3.0 x4 link and the drive model; Windows Device Manager will also report a Gen3 x4 NVMe controller.
