    Yes, you can. However, it won't utilize dual-channel RAM. What I would do is RMA the board in order to achieve full functionality.

    Thanks Danny Boy, what does RMA the board mean ? will it work as well as it did on dual 4GB RAM ?

    I beg to differ with @dannyboy2233 about the compatibility of 8GB but I'd definitely agree with him on the RMA part. It is better to replace the motherboard. Maximum your motherboard supports is 8GB. It has 2 slots and max per slot is 4GB. Hence, single 8GB is not compatible and there is no release of any BIOS update so it will not work.

    Btw, how did you come to the conclusion that the slot is defective? Just curious.:?:

    Thanks for your reply. I took the CPU out to clean the old thermal paste from the sides of it and then replaced with new thermal paste and when I tried to start the PC it failed to boot and bleeped. after swapping the ram modules over it still failed. I got it to boot on one piece of RAM ok in the good slot, so I swapped it with the other piece and it booted ok too. I also tried both sticks of RAM in the faulty slot and they both failed to boot.

    That's bad. Alright, if you have the motherboard under warranty then exchange it. Hope everything works out for you..
  6. Yep, replace the mobo, this is limited to a 2x4GB config, so stuck at 4GB as is
