I confirm that the card was measured without any type of power supply and without batteries, nothing connected....

The ground resistances are:
L7310 : 15.6 ohm
L7320 : 15.6 ohm
L7630 : 268.9 ohm - but every 6-7 seconds it drops to 140-142 ohm,to then go back to 268.9 ohm...

I have already tried reflowing all the RAMs as in the video, but the problem is still there, 3 beeps.
Unlike the video on my motherboard there are 4 memory banks I unsoldered 3 leaving 1 and the problem remains. I also unsoldered the last one and the problem remains I think because without ram. I reballed 1 chip but nothing same problem.
