Ремонт: Ноутбуков, Компьютеров :: RTX 2080 tracing disconnected pad under memory

here is schematics for msi 2080
viewtopic.php?p=793856#p793856

you mean the available schematic does not contain what i need?

any other way to trace this pad

It seems this pad routes to GPU completely in internal pcb layers, so..
Just idea:
- find all other control/data gpu pads, connected to C0 mem chip pads
- on gpu measure several corresponding ball's R and/or Vf to/from ground ball
- search gpu "mem-C0" area for any wired, but not connected pad, check if corresponding gpu ball has same R/Vf as measured before

Hi all First of all am sorry for posting in english in a russian forum but this forum is the only forum with such knowlage I have asus rtx 2080 dual 8 gb with error on fbioc0 i replaced the module but the error remains now i removed the memory module and found a pad DQ1_a does not have a resistance to ground i removed the gpu and its not connected to any pin If some knows where this pin is located under the gpu Or if there is a schematic diagram of gpu pins it would be highly appreciated Thanks in advance and best regards

here is schematics for msi 2080 viewtopic.php?p=793856#p793856 BUT it doesn't contain pages (5 and 10) you need:(

Народ, неужто ни у кого полной схемы нет? Mosasha писал(а): any other way to trace this pad It seems this pad routes to GPU completely in internal pcb layers, so.. Just idea: - find all other control/data gpu pads, connected to C0 mem chip pads - on gpu measure several corresponding ball's R and/or Vf to/from ground ball - search gpu "mem-C0" area for any wired, but not connected pad, check if corresponding gpu ball has same R/Vf as measured before
