![]() ![]() While a brand new 2019 Mac Pro 7,1 would have been a logical replacement for my old cheese-grater, it was completely out of my budget for this unexpected upgrade, especially with the uncertainty 2020 has brought to our industry. ![]() At this point, I needed to decide between fixing a decade-old computer or looking for a new system. ![]() It was down to either the logic board or processor tray. I swapped an older system drive build, swapped the RAM, graphics card and even the power supply with no luck. I spent the better part of the day trying everything to get it working again. However, upgrading the firmware is a reversible process (although some refurbished models have a specialized firmware installed that is not publicly available), and users have not yet reported any problems related to upgrading the older model's firmware.I had started spec-ing out an upgraded graphics car from when the unthinkable happened: I sat down to work one day, pressed the power button on the Mac Pro, entered my password and it promptly shut down. The new firmware also enables Mini DisplayPort to deliver audio signals over HDMI.Īpple doesn't support the firmware upgrade, nor does it consider the CPU a user replaceable part exchanging either could run the risk of invalidating AppleCare. Upgrading the firmware also enables Nehalem or Westmere CPUs that can support faster 1333MHz RAM components to do so, enhancing performance above the 1066MHz limit supported by the firmware that 2009 Mac Pro models shipped with. Single CPU machines take standard W-series CPUs, while dual CPU models require dual-QPI enabled CPUs to function properly. Both machines are similar in that they support Intel's new x58 chipset with QuickPath Interconnect using the Nahalem or Westmere microarchitectures rather than the Core-base Xeon CPUs of 2008 and earlier Mac Pros.Īfter the update is installed, it's then easy to upgrade to faster new Westmere Xeon CPUs, given that the new chips are socket compatible with the 2009 Mac Pros. Loading the new firmware results in Mac Pro 4,1 machines (also referred to as " Early 2009") to report they are now Mac Pro 5,1 models (" Mid 2010"). The discovery, originally discussed on forums and detailed by Chris Foresman of Ars Technica, allows users of the earlier Mac Pro models to install an EFI firmware update that essentially converts the machine into the 2010 model, albeit lacking the faster CPUs and RAM that Apple began installing with the new model. Wednesday, May 11, 2011, 01:00 pm PT (04:00 pm ET) The discovery of how to install new firmware updates on 2009 Mac Pros enables the machines to support dual six-core Westmere Xeon CPUs, faster 1333MHz RAM, and adds audio-out support to the Mini DisplayPort interface, features that were not delivered by Apple until mid 2010.
