With all due respect to ASUS support, I don't buy the memory incompatibility reasoning. Don't get me wrong, it could very well be that the memory is still dead, it's just that it doesn't up & die overnight because of incompatibility. The QVL is just a list of modules that ASUS has had a chance to test and has verified working properly. The testing is not exhaustive nor ongoing. That means there is a potentially a bunch of memory that never even gets tested. And modules that fail testing have stability or performance issues, not a 6 month suicide pact.
You have more than one module so you have testing options. They both wouldn't die at once so try one module at a time and see if you can boot. If that doesn't work then it isn't the memory. From there you can try removing the motherboard from the case, CPU from socket, inspecting the socket/cpu and reassembling on a non-conductive surface.
