USED MAC PRO 2012 12 CORE UPGRADE

I'll order the 1333 Mhz memory upgrade today (didn't want to jinx myself).

USED MAC PRO 2012 12 CORE PLUS

I counted turns of the heat sink screws for CPU A but used the "finger tight plus 1/4 turn" method for CPU B. I liked knowing I could boot with CPU A before installing CPU B, I think this would have made troubleshooting easier.

The Web instructions have you install CPU A first, then remove CPU B and after this test CPU A alone in the computer. Pindelski or I will be responsible if you damage your processor board while attempting the upgrade - if you're concerned, go back to the present day version of the page and let the pro do it.īoth processors POSTed on the first try. The Wayback Machine will get you where you want to be will get a beautifully illustrated (Archived) guide to doing the upgrade ( Link removed after Guide was pulled from Archive), much nicer than the video.

Geekbench 3 with this setup gave up an 18255 multi-core score. I had already upgraded the firmware (to the 5,1 version) a while ago and dropped in an Accelsior 960 GB PCI-e SSD (an amazing piece of gear in its own right). Apple's top config was dual X5670 (95W TDP).)Īfter reading, thinking about it, reading again then thinking some more I finally decided to upgrade the processors on my Early 2009 Mac Pro to dual 6-core 3.46 GHz Xeon X5690's. (I know many owners won't go this far for a CPU upgrade but your notes and the video should be useful for those that are willing.)Īnd IIRC, the 2010 MacPro5,1 firmware also added support for audio over MDP as well as faster ram and 6-core CPUs.Ģ009 Mac Pro -> 12-core 3.46GHz Upgrade - Dual Xeon X5690 CPUs Thanks Mark, appreciate the notes on problems you saw and what you did to solve them. Some will be lucky and it will work the first try. Once I got CPU A right and it seeing all my RAM, then I put in CPU B. Also unlike the video, do CPU A first because if you don't, you won't be able to tell which heatsink to tighten or how much. These are points the youtube video doesn't make. I also want to tell the readers that when your remove the glued down fan/temp wires (they are very fragile), take a very small flat head screwdriver and slide under the shrink wrap, slowly pulling up. Watch the youtube video of this guy and you will get there. Be patient, it really works! I left out the obvious like tools, thermal paste and cleaning and prep. The trick is not to panic when things go wrong. I paid $370 for the Processors and now my Geek Bench is slightly over 26,000 - that's pretty much double my 2.26GHz 8-core. Follow this guy's (youtube video) tips: "Mac Pro 2009 CPU upgrade 8 core Nehalem to 12 core Westmere". If your heatsink fan connectors don't seat far enough down you will never post. I used a small mirror to look into the heatsinks and made sure the fans were spinning. So I took out the second nylon washer on each screw and made slight equal tight and loosen adjustments and after several attempts it finally posted as a 12 core Mac with 24 gigs RAM. After many more adjustments of B CPU heatsink it still would not POST. I then made very slight adjustments to CPU heatsink A and the lights went out but when I checked my "about this Mac" it saw only the A CPU.

The fan speed was normal but I had red lights on the CPU board.

The fans on CPU A were at full speed and no matter what adjustments I made they stayed at full speed until I put in CPU B. I replaced the second washers with one's half as thick and now it posted with the 3 sticks of ram. I had a problem POSTing ( Power On Self Test), so when I looked closely at the processor under the heatsink I noticed it wasn't down cleanly on the socket. I put in (2) 1mm nylon washers on each heatsink screw and slowly tightened them down first on processor A only. ( Ref: Intel's X5670 specs.) I read everything I could find but so many things can go wrong. I finally got my nerve up to buy a matched pair of used X5670 2.93GHz CPUs.
