rtx 3090 passes mats, wont run mods or install driver

[davetheshrew]

Hi

Got a gigabyte eagle 3090 that had a blown 12v vrm and two fuses so fixed them both, card boots.

It passes mats mem test no problem but if I run any mods test I get black screen and no response. Same if I put it on windows, install driver, black screen, nothing.

Any ideas? I checked all resistances and voltages and all seems good, its very confusing.

Thanks

ok mods log is saying

pci device dropped off the bus
nvrm: assertion failed: 0x0000000001d957df
bp @ <fileid:0x003a3>:1922

starting to wonder if either the gpu is dead (even though it displays) or if when the vrm blew it caused a short somewhere under the gpu. Think a reflow might help? or full reball? or am I missing something and its not the gpu at all?

ok can someone just tell me one thing, are the vrms on a 3090 in pairs? so two per phase? Wild guess but if they are then its likely the one next to the one that blew is bad also? anyone chime in please?

check phases with scope, it will show u if any is bad
