      Hello guys,

      In 2018 I bought you a macpro with these specs :

      • MacPro5,1 – 6 Core 3.46GHz X5690 (2010)
      • 32GB (4 x 8GB) 1333Mhz DDR3 ECC
      • AMD RX 560 4GB (1204 StreamProcessors) (OS X 10.13.4+) (New) (Slot 1)
      • Sonnet USB 3.0 PCI-e (4 x USB 3.0) (SON-USB3-4PME) (Slot 2)
      • 500GB Samsung 970 NVMe SSD (10.13+) (Bootable) (1,500MB/s) (Slot 3)
      • macOS 10.13 High Sierra (Recommended

      I’ve 2 questions for you :

      1. I work mainly with Creative Suite and recently i had to work on very big files, so now i need more RAM !
      I read on many websites that MacPro quad and 6-cores can upgrade to a maximum of 48 Gb (3 x 16 Gb)…
      On OWC website they say that you can’t put a fourth module of 16 Gb“due to an OS system limitation”.
      …Whereas on macfinder.co.uk, I can buy a MacPro6-Core Xeon 3.46 GHz 2010 (exactly same specs as mine) with 64Gb RAM.
      So… Can you tell me if it’s useless to upgrade to 64… or not ?
      2.I’m still on High Sierra, can I upgrade to Mojave with my GPU ?
      Thanks a lot !

      With the X5690 you can run up to 4 x 16GB modules in your Mac pro. I have them available for £25.00 per 16GB module. [email protected] if you need any.


      Yes your GPU will support Mojave and even higher, up to Big Sur if you use opencore.

      The X5690 allows you to use up to four 16GB modules in your Mac Pro. I’m selling these for £25.00 per 16GB module. Yes, if you utilise opencore, your GPU will support Mojave and much higher, up to Big Sur.
