I am working on AMD 7900 XTX board that initially had faulty E, F, G, H memory channels (near PCIE). Board is also bent.

I have reused G and H modules and put new E and F modules. Now no failed channels are detected, but I measure VDD_MEM - 0.4 Ohm to GND.

Other measurements are as follow:

VDD_SOC - 0.7 Ohm VDDCR_GFX - 0.3 Ohm VDDCR_USR - 4.4 Ohm VDD_MEM - 0.4 Ohm VDDCI_MEM - 11.3 Ohm 1.8V_S5 - 379 kOhm 0.75V - 48 Ohm 12V_BUS - 4.4 kOhm 3.3V_BUS - 1.3 kOhm

I guess it is either dead core or something else is shorted on the VDD_MEM line.
