Hello, is it possible to put 2x 4Gb Ram in this model?

*By default, 1 GB is installed as a single module (MB463LL/A) and 2 GB is installed as two 1 GB modules (MB464LL/A). Officially, this model is capable of supporting 4 GB of RAM, but as first reported by MacminiColo, this model unofficially can use 8 GB of RAM after applying EFI Firmware Update 1.2. http://www.everymac.com/systems/apple/ma

I think this is not unofficial anymore. As per apple support, this model admits up to 8GB
