Lol so I called MemEx to get my RMA number to give to AMD so they could try and expediate it, now MemEx says that the RMA is closed by AMD and that I can get store credit or a refund...
I asked how the RMA got closed, and she said that the vendor decides to do that if they aren't able to provide a replacement. Interesting how that happened on the same day I called to get the RMA # and after they said they'd call me back.
I guess I'll send the RMA # to AMD, maybe they can do something.
