    Hi,

    I have been having some issues with my Mac Pro where it would say "you need to reboot your computer" only on a reboot during post. Also the USB would drop out randomly and ethernet wouldn't work at all. I took it to the Apple store although it was out of warranty. At first they thought it was the logic board which is what I was going to guess. They replaced the logic board, all memory, and hard drives, and have determined it's supposedly both the processors. I find that a little crazy for both procs to be bad..... They said the cost of a repair would come out to 2300 dollars! I might as well buy a new machine at that point. Before I do that though, I'd like to see for myself if it is both Procs or just 1. I have the service manual for the early 2008's but was wondering about the memory configuration. Can someone shed some light for me how to configure the memory with a single quad core installed?

    Thanks,

    Victor

    Take one CPU out and then try?

    It will run with just one in it...

    Right, that's what I want to do. But how do I configure the memory on the two riser cards for 1 proc? I know on the 2009's it's different.

    I don't think it matters TBH.

    If it doesn't like it it won't boot at all, not just crash.
