Thanks for replying & agreeing to replace for a new motherboard but not being funny I sent this back almost 3 weeks ago & got an email from OCUK on 10th Jan saying it had been sent back to you then. Are you saying you only just received this on Tuesday 23rd & it took 13 days to reach you?AWPC, you messaged me directly and I have been dealing with your direct message to me. You sent the X399 board back to OCUK and they have now sent it to us, we got it on Tuesday and the unit has already been swapped for a new unit and returned to OCUK. They should be sending it back to you, we are testing your failed board to understand why it failed. In regards to the 1070 VGA card, OCUK have confirmed to me it has been returned to the other company who made it and they are dealing with that RMA.
I still love this motherboard design I think its the best I ever owned & despite the long delay I have not soured yet on Gigabyte (I still have 3 X Gigabyte motherboards in daily use in other systems which have been reliable for many years) but I think you will agree its a concern if you do not know what caused the failure. I only used the PC for light PC gaming, web browsing & watching movies its not like I stressed it much at all and my PSU is a very high end Seasonic 1050W as are all my other components.
