Hello, I have a Dell Inspiron 546s with an amd Phenom triple core cpu and i got an AMD Phenom quad core HD985ZXAJ4BGH CPU. THEY ARE BOTH SAME SOCKET TYPE BUT I THINK ONE CPU IS AM2+ and other cpu is just AM2. Will the quad core listed above work in a Dell Inspiron 546s slim tower? Thanks in advance for any help you can give me.
