Need help
Zotac gtx 1070 Ti Mini - NO Display
All power rise, except for vram (controller by RT8816), try to replace RT8816 but still power not rise
Resistor 2R2 burned before (2 pcs, back near RT8816 and front under coil vram), already change them but same result
picture
1. Resistance pcie line 3.3v very low, 14 Ohm, 0.029 on diode. but power 3.3v rise appear
2. Front Top left card, AAM7MB very hot. without this AAM7MB Resistance pcie line 3.3v still low

1. Resistance pcie line 3.3v very low, Problem with chip gpu? or any idea where to start digging
2. any one known what this part AAM7MB? datasheet

aam7mb - replacement apl3516
resistance 1.8 and 1.0 ???
check signal lines pcie and dp-hdmi-dvi on gpu side.

1.8v 530 Ohm / 0.470 diode
1v 25 Ohm / 0.043 diode

Chip gpu? 1070 arround 900 Ohm on 1.8v right?

working videocards ~ 100 Ohm.

check - POSSIBLE problem with pex power 1.0v ic >>>> low resistance 3.3v

You have to find similar boardview from MSI since there are all of them on the forum. Locate 3.3V and look what is connected to this voltage rail. Also a thermal camera would be helpful.
You have to eliminate one by one. unsolder, measure, solder back.

As I said. Start from the beginning. Find MSI boardview which is similar. Track what is connected to this voltage rail and eliminate one by one.
