    rtx 3090 passes mats, wont run mods or install driver

    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?

                   Palit RTX 2080 Super Jetstream Mats/Mods help
                  by Maxim Bojko
                  Hello,

                  I have a RTX 2080 that is broken, but interesting thing is that the card works how it should work, but when playing the card crashes, black screen fans go to 100% and nothing happens anymore. I changed thermal paste because I thought it was overheating, but no. So I checked with gpu z and here is what I had.

                  After a while a dude I got friends with told me to underclock the gpu via msi afterburner. First to underclock the core speed by 200 then open the chart for the mhz and voltage and said that I should change the mhz at 0,9v to 1900mhz. Since then I doesn't crash...

                  Mats / mods: detected and repaired GPU fault. Cant seem to test after!
                  by chronic519
                  Hello.

                  GPU came in, green lines. Spent lots of time using to get the Mats / mods drive working (found on youtube).
                  Found issue with a RAM block
                  Replaced, green lines gone.
                  Trying to test again, assuming getting the false positive. Originally had over 1K on a single bank. Now getting tosses low between banks.
                  Used a good card to test and same results low errors 32+.

                  I am just search for some form of command to do a full test on the GPU.
                  I just ran the mats command with my good GPU and passed after roughly 40 min.
                  The repaired one, ran...

This ensures that all modern games will run on GeForce RTX 3080. Additionally, the DirectX 12 Ultimate capability guarantees support for hardware-raytracing, variable-rate shading and more, in upcoming video games. The GA102 graphics processor is a large chip with a die area of 628...

                  About MODS & MATS
                  by 00__Nomad__00
                  Do MODS & MATS work with older nVidia GPUS, specifically the G71 M ?
                  I've tried versions 173.48, 400, and 455, but it can't detect the GPU, even though the GPU is detected in Windows and functioning properly. I couldn't find any lists of supported GPUs.
