Review on 💥 ROG Strix Z590-A Gaming WiFi 6 LGA 1200 Intel 11th/10th Gen ATX White Gaming Motherboard with PCIe 4.0, 14+2 Power Stages, WiFi 6, Intel 2.5 Gb LAN, Thunderbolt 4, 3X M.2/NVMe SSD, and Aura RGB by Hunter Feerey

I'm having strange compatibility issues with the new PCI 4. My M.2 drive speeds up and down with my Samsung 980 M.2 drive as it does with mine Computer is not sure these problems with PCI 4 M.2.Update with built-in audio, if you insert PCI 3 M.2 drive into the bottom two ports, the audio will be terribly slow. I had to disable onboard audio and use a Sound BlasterX AE-5 Plus card.
