I sure hope so!
The next time you're considering a CPU or other hardware upgrade, my suggestion would be to ask before you order.
The Dell CPU is validated. We never tested the retail one.
UP673 Kentsfield Quad Core QX6700, 2.66GHz, 8MB, 1066FSB, B3
I thought I had ordered something else, then when I read the fine print it was different!! Anyway I installed it and it seems to be working fine, but now the CPU fan sounds like it is running louder and faster (I used the original). Don't know if that's indicative of a current or soon-to-be problem.....What do you think?
