Review on 💥 ASRock X570 Extreme4: High-Performance AM4 Motherboard with HDMI, M.2, and USB3.2 by Chase Cooper

then it asks for 20 PCIe lanes for the processor and there are 16 total. To get it to boot you can update the BIOS and then switch the PCI to give each slot the maximum x4 speed. All X570 motherboards I've reviewed from other manufacturers support x8/x8 mode for Ryzen 3, so being stuck at x4/x4 is already a frustration for anyone who wants to have 2 graphics cards for whatever reason. But it gets worse. You can BOOT after installing PCI video on x4/x4. but you cannot output video from either card. TL; DR: You can't have 2 graphics cards on this board, even if you only want video from one of them. This is a terrible problem for me - I would return the board if I could but ASRock tech support took so long to help me figure out that the board just can't use 2 graphics cards that I can't now can return.2 . It misdetects DRAM speed, voltage or timings. General. All the timings for my DRAM were double what they should be, the voltage was 1.2 instead of 1.35, and the speed was 2133 instead of 3200. The chipset fan is very noisy initially, but you can turn it off until the temperature rises and then increases as needed.
