2. NVIDIA RTX 2080Ti only works properly on PCIE slot 2?

If the NVIDIA RTX 2080Ti functions correctly only in PCIe slot 2, it indicates a potential issue with the primary slot, necessitating further examination or potential motherboard-related troubleshooting.

3. Graphics card only works in the second PCIe slot?

If the graphics card operates solely in the second PCIe slot, there may be issues with the first slot, requiring investigation into potential hardware problems or motherboard compatibility concerns.

4. RX 6600 gpu only working on MSI B660M”s Pcie 2 slot (black screen after booting)?

If the RX 6600 GPU functions exclusively in the PCIe 2 slot of the MSI B660M motherboard, it suggests a potential compatibility issue or configuration requirement with that specific slot.

5. GPU struggles only in the primary PCIe slot. Is this a motherboard issue?

If the GPU encounters difficulties in the primary PCIe slot, it could indicate a potential motherboard issue. Further investigation and troubleshooting may be needed to determine the cause.

6. What the heck? Graphics card only works in one slot?

Surprised or frustrated, the graphics card functioning in only one slot prompts confusion. Investigating hardware compatibility or potential issues may provide clarity and solutions.

7. Same GPU won’t work in first PCIe slots in 2 different motherboards?

If the same GPU fails to work in the first PCIe slots of two different motherboards, it suggests a potential issue with the GPU, the PCIe slot, or a compatibility problem.

8. PCIE Slot 4.0 Not working and No display on 6700 XT?

If PCIE Slot 4.0 is not working and there’s no display on the 6700 XT, potential issues could include hardware compatibility, driver problems, or a malfunctioning slot. Troubleshooting is advised.
