I've just completed an HTPC build with one of the new Kaveri processors. In order to make this happen, I had to flash the Gigabyte motherboard's BIOS to support FM2+ from a Windows install using an older, two-core AMD A4 I picked up cheaply. Windows seems to have mostly adapted to switching out the APU, except that the performance manager and task manager see only two cores (but four "logical processors,") although they say the correct name of the chip itself. In the Device Manager, four cores show up. So my question is, are all the cores being used or not? If not, is there a way I can get Windows to recognize them? Thanks, all.
