After further investigation, may also need a new vROM too on top of adding microcode since my PC is dependant on integrated GPU. Snooping around in my BIOS image revealed support for Kaveri vBIOS but not the new Carrizo CPU that I have, but my chipset is Bolton D4 [A88] so should be compatible? I'm sorry, this seems to have become quite an extensive project. $20CAD via Paypal to whoever manages to get my BIOS working with A8-7680.
