Mac Pro 2010, cpu upgrade stuck at Apple Logo

[nudoru]

I picked up a 2010 dual 4 core tower a while back with the intention of upgrading it over time. I just "finished" upgrading the CPUs to dual 6 core and it's stuck on the Apple Logo screen. From what I've seen on line, this is a "good sign" since it booted this far. Looked at the verbose mode output, it freezes after the "End RandomSeed" line.

I'm not sure where to go from here. Seems like the CPU and Ram would be tested prior to the chime. What should my next steps be?

Put your original Xeons back and check if you can boot correctly. After that, test each Xeon on CPU-A socket.

I tried each new CPU opposite sockets, with new cpu A in A it froze at the Apple logo, with new cpu A in B there wasn't a startup chime. It's booting fine with the originals back in. I think one or more of these new ones is bad for sure and have contacted the ebay seller for a replacement.

^^^^The machine won't boot with a CPU in socket "B" and none in socket "A". Did you try the other CPU in Socket "A"?

I tried to boot it's with only CPU A in socket A but it wouldn't boot. I also swapped them so that each CPU was tested as a pair with each in the other socket, CPU A in A CPU B in B and the other way around. I contacted the seller and he's sending a new pair so I'll get to try again in a week or so.

You can test just Xeon-B into CPU-A socket.

Also make sure you're running in single-user mode, so that you'll see kernel panics.

You mean verbose mode?

I did test just A in the A socket and it didn't even chime. If it was supposed to work, pretty sure that it's broken. I'll test the new pair when they arrive.
