Hi

My pcie slot has failed but my otherone works fine I have already rma my board once and I really don't want to send it off again. I am not going to use SLI in this board and have put my gpu in another 16x slot and it all is working again fine is it safe for me to just use the working one and forget about replacing the board once again. I have like a year and 8 months warranty anyway and later on down the line if I decide to go SLI I will replace it.

Perhaps, but I would be more concerned about the defective components that caused the slot to fail. Usually, the problem will spread to other slots/components. Most defective boards are caused by capacitor and electrical issues that can affect anything on the board.

I would just replace it. I certainly wouldn't let the warranty run out without replacing it. These electrical issues may also effect other components that aren't related to the board like your hard drives and GPU.

The big question here is what killed what? Did the motherboard's PCIE slot die on its own or did it get 'help' from the GPU? If the GPU is defective, it may end up killing every slot you put it into.

There is also the possibility that the first slot dying damaged the GPU and the damaged GPU might kill the second slot.

If your second slot dies similarly to the first one, you might want to replace both the motherboard and GPU.

If you have an Intel-based system, the GPU slots' PCIE data lanes are driven directly by the CPU so if what "failed on your board" is the PCIE lanes, chances are you need a new CPU.
