    MP 1,1-5,1 cMP 2.1 slower using SSD than HDD

    Hi guys, got a cMP 1.1 for peanuts. It was working decently (and by decently I mean astonishingly fast for a 15 yo computer), booted in 10 seconds, overall workflow was great & snappy. I wouldn't be myself, if I wouldn't try to make things better, so I took an SSD laying around (it was working...

    macOS Big Sur on cMP 5,1

    I was encouraged to share my experience with installing macOS Big Sur on two of my cMPs as I wasn't able to find anything already prescribed for those like me who use the RefindPlus/OpenCore Chainloader, and hopefully it covers off some useful information for others attempting the same. I have...

    MP 1,1-5,1 Latest on cMP and FileVault?

    Hi, I tried to understand the state of things as far as FileVault (aka APFS-Encrypted) on cMP units is concerned. Read some threads here and on MacVidCards' blog, and still confused. I have a MP4,1 updated to 5,1 with a vanilla RX580 and 10.13.6. Considering whether to update to Mojave or...

    MP 1,1-5,1 5,1 cMP & GTX 1080

    A friend gave me his unused GTX 1080. I'd like to get it working in my cMP. It seems that Nvidia drivers work up only to 10.13 (I'm on 10.14 at the moment). I'm using this to run Folding@Home applications for COVID19 research. AMD cards (like the RX580 I have) aren't optimized to run...

    MP 1,1-5,1 OpenCL vs. Metal with Mojave on cMP 5,1

    I upgraded to a metal-compatible GPU (Radeon RX 580 Pulse) primarily because Mojave requires it and the clock is ticking on High Sierra. Now I'm trying to figure out whether or not to utilize metal or OpenCL for Photoshop, Camera Raw and photo stacking. I found comments on online forums saying...

    Resolved Mac Pro Server (Mid 2012) strange antics powering up

    Just bought another cMP 5,1 Server (Mid 2012) Quad-Core (single CPU). When I first plugged the power cable in it started automatically before I even hit the power button. All good, so I upgraded the firmware from the original 7F to 89, then popped a RX 580 in and upgraded to, but...

    Everyone knows our dusty machines vrm cooling section attached to cooling blocks. When we upgrade 2009 cMP's with 130W lidded CPUs, cooler height increase nearly ~2.2mm. After all, thermal pads should be used 4.5 or 5mm to avoid future overheat problems. Vrms forced extra and cooling solution...

    MP 1,1-5,1 Pulse RX 580 8GB or Pulse RX 590 8GB?

    The Pulse RX 580 is a supported GPU, and the Pulse RX 590 also probably works in cMP from other reports of success that the Nitro RX 590 works. So is it safe to go ahead and get the Pulse RX 590 and that future macOS support will follow if Apple continues to support the RX 580, or are there...
