The new X570 board and R7 5800X are not recognized by the system.
I installed the X570 but it won't start. The motherboard has four LEDs showing RAM, CPU, BOOT status and a warning light for the process stage. With the R7 5800x it freezes at the boot menu. I assumed an update was needed since the X570 seemed to be the latest chipset, so I installed the newest BIOS and tried the older R5 1600, hoping it would work with earlier models. It didn't boot and stuck on the CPU LED. There are three 2x2 power connectors on the board. I managed to connect only two (to meet the 2x4 requirement), assuming the CPU could still boot without all four lines, since my old board only had one. What might be causing this issue?
It seems the system isn't recognizing anything. The design of modern boards makes it tricky to identify issues. You can test by connecting the speaker to the front panel header and counting the beeps. In the explanation below, you'll find the codes listed. Refer to "AMI beep codes" under "Under," which will verify drive errors or missing boot devices. Scroll down—letter D clarifies your problem. https://www.asus.com/us/support/FAQ/1042678/
You're likely seeing an outdated BIOS notice. The CPU documentation indicates your older 1600 model isn't compatible with any update. Also, look inside the motherboard packaging—there may be a label showing the current BIOS version.
The new board arrives ready for shipment for the 5000 series CPU. But you only receive the CPU LED when the 1600 is connected, since the BIOS now supports the latest processors and older CPUs may no longer be compatible. With the 1600 included, the CPU LED appears first, followed by booting last. Your board with the 5800x passes the self-test to the boot device (M.2 drive). Confirm?
