More notes on 2009 Mac Pro Northbridge Heatsink Retainer Repairs/CPU Upgrades
(from a reader that reported on repairing 2 'dead' Mac Pro CPU boards in December.)
"More on 2009 Mac Pro upgrades & northbridge (heatsink retainers)
Hi again, I got some more "dead" processor boards, so far only one was actually dead, the rest were northbridge heat sink repairs. I think I'm 5 for 6, now.

I finally did the dual processor upgrade. The youtube video (2009 Mac Pro 2009 8 core Nehalem to 12 core Westmere upgrade, linked in an earlier report) was accurate, but it's way less scary than made out to be. A matter of a few minutes, once you have the materials on hand. I did have to clip the heat sink power leads, but as an interim, you can use Macs Fan Control to slow down the fans (running on high if the connector isn't seated). I ran one processor with the connector unseated for a couple hours just to show that even without the connection there is no heat issue. My heat soaking application is still the dnetc client (where the team is still in 13th place) and the dual hex 2.93GHz setup is essentially twice as fast as the former dual quad 2.26GHz for this app...

Thanks Dana. (Checking on the other question you had. There was an (unofficial) Mac Pro 1,1 to 2,1 EFI updater but don't recall other than X53xx CPU upgrades w/2006 models.)
