I have an ASUS-V551LB-DB71T and called Asus to check if the CPU was socketed. They looked it up and said yes it was. I then used CPU-z, the CPU is a I7 4500U, socket 1168 BGA. BGA= Ball Grid Array=ment to be soldered to the motherboard. This not the first time Asus has given me incorrect data. I asked about adding an M.2 SSD since I saw a stencil on the Motherboard saying "SSD" . They said no SSD socket is provided. My M.2 SSD is working fine in this CPU for over a year now. What is the Story with a processor upgrade? I want to upgrade the I7 dual core to an I7 quad core so I Can use it with VM.
