So I have an hp pavilion p7-1020 that I beefed up a little bit a while back. I have a N-Alvorix-RS880-uATX (Alvorix) motherboard and I just bought a AMD Phenom x6 1090t CPU and I installed it, but when I tried to boot up my computer it said that I had installed an unsupported CPU. I have no idea what's wrong. I would appreciate some help with this! Thanks!
