So i troubleshooted my mac and came to the conclusion that my logic board doesnt work anymore. ( it was a good run 6 years ) my friend just told me that they dont make the logic board for the first gen anymore. i have quad.core . i was wondering , where do i go from here. i dont want to buy a Refurbished logic board cause it only comes with 90 day warrantty.

can i use the newer gen. mac pro logic board with my first gen quad core processor?

Are you absolutely sure the logic board is bad?

At this point I'm of course not sure what the problem is (since you didn't say)...and what sort of testing/troubleshooting you have done so far. But if you're REALLY sure it is the logic board...what sort of prices are you seeing for a replacement logic board?

The reason why I ask is...first gen. Mac Pros are selling for around $500-$600 on e-Bay. So if the replacement logic board is close to that (or even half of that)...maybe just purchasing another exact unit would be a better choice.

Of course you could apply the same $$$ towards something newer if that works as well.

What makes you think it is the mobo and not say the Power Supply or Graphics Card or hard drive? You can still purchase them new. Not cheap however:-


661-3919 Apple Mac Pro Desktop Intel Xeon Logic Board

Might pick a used one up much cheaper on eBay etc. Here is one to get you started:-

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

And what dud you mean about the Mac Pro graphics card? Cards must be manufactured as Mac Pro or flashed PC cards. PC cards will not work natively. Some graphics cards have no cables to the mobo, some have one and the more upmarket later model cards have two such cables.

Suggestion was to check the cables out. Fair bit of heat in there can make them brittle and liable to fail.

No answer it should not unless it is a very very rare PC/Mac compatible card. Graphics should commence within five seconds of booting.
