Hi everyone,
I've got a strange issue with a X570 AORUS MASTER Rev. 1.2 motherboard. The owner (my cousin in law) told me that over time he got more and more bluescreens until the board won't boot/post anymore.
It showed only post codes "C8, C3" and won't boot
I found a few things:
- cpu was faulty/dead (For further tests I replaced it with my own ryzen 7 3700X)
- with new cpu motherboard only runs on BIOS version F22 and below
-> And windows only runs stable if I set PCIe in BIOS settings to Gen 3. On automatic settings I got random bluescreens and USB ports and onboard LAN/WLAN won't work (showed power failure error in windows device manager)
- with BIOS F30 and above the "C8, C3" post code issue returns (flashing with Q-flash plus)
What could be responsible for this behavior?
Main power rail voltages are fine.
The only thing what got my attention was a very low resistance on PM_1VSOC/PCHIO (only 3 Ohms, but reading of 1V was fine and stable) -> comes from Chipset/PCH side
But I don't know if this is too low or not?
I also tried different CPUs and memory/RAM, another power supply and different graphic cards
