Can overclocking a GPU harm PCIe x16 slots?
Hi, today I experimented with overclocking my GPU to check its impact on gameplay. However, after adjusting the voltage and MHz clock, nothing changed. Eventually, I left to eat, returned, and noticed the screen was black with the VGA light on. Switching the graphics card to a different PCIe X16 slot resolved the issue, indicating the original slot might be faulty. I also tried another GPU in the bad slot, which also failed to work. Could this overclocking have caused damage to the PCIe slot?
It includes an 8-pin connector rated for 150W, though it's typically safer to exceed that compared to the 75W PCI-e slot. At 1480MHz clocks, the RX580's power use will be significantly higher than at standard speeds, especially if Sapphire splits power allocation—such as 70W through the PCI-e and 100W via the 8-pin—potentially exceeding the PCI-e limits. Power consumption varies unevenly during GPU operation, with fluctuations across different models. A test would be helpful.
The graphics card is connected via a PCI-e port designed to deliver up to 75W. Increasing the overclocking could push usage beyond this safe threshold, risking damage. Many cards draw significantly less than 75W and rely mainly on the power supply, though a few may consume around that amount. Which model are you using?
I own an RX 580 Sapphire with a 4GB RAM module. My settings are around 12 plus voltage and 1480 MHz.

Another issue occurred with one of my x1 to x16 risers (007c) on the mining rig today. I have six Asus GTX 1070 graphics cards. My overclock configuration was: power limit at 112%, temperature at 70°C, core clock at +100, memory clock at +500. Recently, I reduced the power limit to 95 for now.
