Ok, thanks for the info.
I guess I should have modified my question to, has anyone successfully installed a E7400 CPU in the P4M900T-M motherboard? I have seen some people seeling them online and claiming the system comes with a E7400. However, since the processor is not on the list of supported CPU's, I'm not so sure it will work. Also, keep in mind, the list ECS published was on 03/19/2008, which might be out of date. I guess it's not worth the hassel or waisting $70 for a CPU that does not work in my board. I will just upgrade to a new board.
Thanks again,
Chris
