Hi I'm working on that asrock motherboard. It had shoted mosfet on cpu phase(changed) and 1 cap on bottom side(changed). Led driver is probably shotted too because voltage on one leg of this chip is 0.5v to 5v (its in loop rising and falling) its's RT7905 and i cant find datasheet :/ But its only led driver so mb should work without it. When i desolder it on the same leg is 5v all the time.
If i start mb on all cpu phases is 1v1 for a few seconds only. Other voltage are present. So i tried to flash bios with the newest on official site and it doesnt help. Its not normal extension so i have to rename file to bin to flash the bios. When i tried to read ic after flashing its looks ok but it behaves as I described.
Maybe somone has this mb and can send me bios whichone is tested on newer cpus?
I tried on two cpus 4650g and 5600g i dont have olders. Idk what to check now. For me its looklike bad bios. I tested memory slots with tester it looks normal. I have boardview forthis mb if somone need.
