Oscilloscope. Just a cheap multimeter can verify the phase work or not. Yes you cant check for the signal but can check if the phase have frequency. Frequency = running phase....

Thank you. Unfortunately my mb have dead chipset. Actually 2 r5e10 boards have dead chipset.
i just order chipset from china....

I have 2 rampage v edition 10 (x99 platform) have issue. All voltage present exept vcore and vmem. Board stuck at code 00.
Refer to boardview file of similar board (rampage v extreme) i think enable of vcore somehow relate to the TPU chip.
i can read/write firmware to the eeprom chip, but i can not find anywhere the know-good firmware for the board.
can you give me some tips?
i think the firmware for iROG chip can get from bios file but right now i dont know how to extract it....
