I recently assisted a friend with upgrading their Ryzen 5 3600X and ASUS TUF X570 plus, including a Wi-Fi motherboard. They reported slow performance in BIOS, especially noticeable when moving the mouse or using arrow keys. The CPU clock appears to be underclocked below 1GHz without any adjustments, even after updating the BIOS. The motherboard seemed fully functional at first, but now it’s causing lag. This issue seems unusual since the board was new and reported as working perfectly by the seller on eBay. I’ve tested the Ryzen 5 3600X in their system and it runs smoothly, along with the RAM. What could be causing the motherboard to auto underclock such a CPU? I haven’t seen a brand-new board used this way before.
Low-frequency clocks below 1 ghz, occasionally around 900 MHz, suggest the CPU is operating in an emergency state due to an issue. Reset CMOS, verify temperatures, inspect power connectors on the board for damage, and examine the socket for any harm. Ensure the fan header on the CPU is functioning properly. Did the seller provide evidence supporting this claim? There should be a valid explanation for selling a fully working X570 board.
