Will this machine power on with only one CPU?
I recently acquired a 2006 Mac Pro, which, according to the diagnostic LEDs on the logic board, has a fault on CPU B. I've tried replacing the thermal paste and checking all connections, but to no avail.
I've also tried removing the second CPU entirely, but this still doesn't work. The machine powers on and the fans spin up (the GPU fan in particular is rather loud), but nothing happens beyond that.
It may also be worth noting that when both CPUs are installed, the system will push out a video signal, though it's just a black screen. It appears to be restarting endlessly and encountering the same error. When only one CPU is installed no video signal is sent out.
Am I missing something, or can the Mac Pro only boot with both CPUs installed (I've even tried putting the heatsink back and plugging in the temp sensor)?
Bu iyi bir soru mu?
