    Gigabyte RTX 3080 Ti Gaming OC - VRAM read errors

    - I’m troubleshooting a Gigabyte RTX 3080 Ti Gaming OC that throws read errors on all the vram chip.
    - The card powers on and fans spin, but memory initialization fails.
    - Powered-on measurements show FBVDDQ at 1.36 V and PEX_DVDD / PS_PEXDVDD_SW at ~0.96 V, while thermal imaging shows the FBVDDQ inductor heating up.
    - Powered-off resistance tests reveal FBVDDQ Bank ~50 Ω and NVVDD ~1 Ω.
    - Looking for advice on whether this pattern points to shorted GDDR6X chips or GPU internal issues, and how to identify which specific VRAM chips need replacing....

      GPU - AMD Radeon RX 6600 MECH 2X 8G missing voltage

      Hi,

      I have an RX 6600 from MSI, and it has no power. I have found no shorts, and almost all voltages are missing:
      • I have 5V on the back of the card (U310), but it seems to be used for video output (5V_VESA).
      • All fuses seem okay.
      • The thermal camera shows no hot spots.
      • I have flashed the latest BIOS (using CH341A). It makes 1.8v and 0.75v come back

      I am used to repairing shorted cards and replacing blown components, but here I am stuck.

      For schematics and board view, I use the Rev 2.0 PDF schematic, as nothing is available for Rev 1.0. However, Rev 2.0 is...

        RTX 3080 FE Identifying capacitor

        Hi people, I hope this is the correct spot to post this, I'm new to the forum.

        I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.

        I hope these photos make it clear which component I am referring to:
        (yes, the soldering is a bit botched from removing the blown one, I know)

        I have found the board schematic (attached), but there does not seem to be a boardview available. I have never...

          Troubleshooting XFX RX560

          So I got my hands on a broken RX560.

          After measuring the basic resistances and voltages everything appears to be fine, the core itself also heats up and the pc boots up (beep is there, on igpu mode everything runs fine).
          But I just do not get any display output. After looking and touching around a bit I recognized the VRM controller chip (ON NCP81022) and the corresponding low side MOSFETs for the Vcore (uPI M3098M) get very hot to the touch.

          Now I dont have the time anymore to check for any short circuits by injecting voltage in the circuit and checking if anything...
