    Evga gtx 1070 no display

    I've got a gtx 1070 no display all rails present not showing up in device manager or gpuz.
    Core voltage is only 0.67volts is this to low to "boot" core.
    Up9511p controller.
    My vrefin is 0.8v vref is 2v and my vinmon is 1.2v

      Yes.
      Upon further investigation I has signal on pin 1 of bios upon boot so I think gpu is alive.
      Someone has been messing with straps on rear of card.
      All my voltages look good.
      I've checked caps on pcie rails these are all good and on diode mode my lanes all look good got 1.8v on bios chip.
      But still not detected in windows.
      Has anyone got a evga gtx1070 sc Hynix ram I could do with a picture of straps on back of gpu.
      I have one odd looking resistor near straps.

        Post another picture zoomed out so we know where your straps are. I guess most gtx 1000 series from evga will have a very similar pcb layout

          I have micron memory.

                Do you know what the straps are for?
                What's on the other side of that area? Maybe post a picture of the entire card? It usually is easier to find similarities with other cards. Those straps may be similar, but located somewhere else.

                I could not find a match in my donor boards. But I will look in other stacks.

                  Check this:


                  That looks almost identical to yours.
