as you can see here
http://forum.giga-byte.co.uk/index.php?topic=16925.0I have the same problem but a infinite loop with a incompatible ram.
Now i ordered the same ram as u since its offically supported and it will arrive tomorrow.
Can't say i have high hopes for my system to work after reading your thread
Do have a speaker connected to get an error beep code from the board?
Have u contacted the gigabyte customer service?
The CPU only supports 2133 memory. Yes it should run it at default setting 2133. But like I said a lot can't get it to boot with 2400. Plus all the other memory has to be over clock that is why it says DDR4-2400(oc).
The "Qualified Vendors List" goes up to 3400~3466MHz DDR4 ram. At least for me this says the board will work with any ram i pick from the list. If it doesn't work either the list is crap or the board doesn't work as it's supposed to do.
Well lets see how if my system will work tomorrow or not.
