Welcome to Anandtech. Is there any info you may have overlooked in your post about your MB? Doing a google search on the info you gave on the MB type doesn't get squat; same at ASUS site. Possibly some transposed numbers or perhaps you are using a model number for the actual MB designation. Doesn't matter if it is really new; if it has been released, it will be "out there". Is it possible for you to open the case and look at ths silkscreening on the board to get the exact model and revision number of the MB? That would be of great help. Otherwise we would be just guessing as to what options Sony has enabled for your particular BIOS/model.
