I installed the cpu in CPU tray A. Didn't delid, so I couldn't broke it.
You should have giving the specs of your Mac Pro, looks like you have a 2009/4.1
Did you upgrade the firmware to 5.1?
Did you read about the difference between the two?
Here a lot think you need to delid the cpu's, but that is totally not neccesary, just read about what to do,...rivets
Yes, it is a 4.1 2009 upgraded to a 5.1, I guess. Running Mac OS High Sierra. How can I check that I upgrade to 5.1. Bought it second hand.
Yes, it is 5.1
No, I tried it with a non-delided cpu.
Thanks for the support.
I don't want to take the risk. So a non delidded cpu will work?
It is a 4.1 2009 with dual cpu 2.26 ghz upgraded to 5.1. That's 100% right!
I have no access to a single cpu tray.
I'm waiting for the new cpu and try with both cpu installed.
I won't delid them because I see many video's where everything is working good without delidding
I gotcha. Like I said, it's a matter of preference and risk evaluation. Good luck w/ the new CPU...hope it arrives quickly!
