Mac Minis, for example, can drive two displays simultaneously one for your operator and one for your projector. For video folks, what you need depends entirely upon what you’re trying to accomplish. GPU and VRAMįor audio-only users, GPU considerations are fairly negligible. Processors on Macs cannot be upgraded after they’re purchased, but most Macs let you select from several processor options at the time of purchase. Large numbers of audio or video cues playing back simultaneously, for example, benefit from an i7, i9, or Xeon processor which have better handling of multi-threading tasks than i3 or i5 processors. The more work QLab needs to do, the happier it will be with a more powerful processor. QLab is likewise not supported in a virtual machine environment. Please do yourself a big favor, and just keep away from those. QLab is not supported on “hackintoshes” at all. Please take this information not as a firm set of instructions about what to do, but rather as a set of recommendations about what to consider. What follows is a discussion of general concepts surrounding processor, GPU, RAM, and hard disk use for QLab. Starting with version 4.6.8, QLab 4 is compatible with macOS 11 (Big Sur) and Macs which use Apple Silicon (M1) processors.īecause of QLab’s great flexibility and the varied scenarios in which it is used, it can be difficult to determine ahead of time how much computer power a given QLab workspace will require. It requires macOS 10.10 or higher, and will work on any Mac that can run 10.10. Many people however have run two GPUs stacked close together in this configuration without overheating problems so it doesn't seem to be a major issue.QLab 4 is a Mac-only program. This unfortunately reduces ventilation and blocks PCie slot #3. Therefore to optimize performance from GPUs in Mac Pros 3,1 // 4,1 // 5,1 both GPUs need to be in the bottom two slots (PCIe slots #1 and #2). In the 2008 model the top two x4 slots are further reduced to PCIe revision 1 speeds. The top two slots (#3 & #4) will only run at x4 lanes.

The only drawback here is the loss of Drive Bays #3 and #4 to make room for the double width 5770 on the top in PCIe slot 4.įor 2008-2012 (Mac Pro 3,1 // 4,1 // 5,1): Unfortunately only Slots 1 and 2 can run at full speed and and use x16 lanes of the PCIe bus. This will use the two fastest PCIe lane combinations (x16 in slot1 and x8 in slot 4), and allow for increased ventilation, as well as leaving slots 2 and 3 open for other add-on cards.

I notice in my istat menu results (GFX-cards.jpg)įor 2006 & 2007 models (Mac Pro 1,1 & 2,1): The best approach will be to use tpayton's method to install one 5770 in slot 1 (the bottommost slot that accommodates a double width PCIe card), and the second 5770 in Slot 4. Which made me more concerned about this test. but I am a bit concerned about the power? I am waiting for 2x power cable splitters.Ĭoncerned this will draw power from the motherboard and maybe fry it?but I should probably get a dedicated power supply? any suggestions appreciated.įrom what I have read, slot 1 and 2 are more powerful at 12lanes and 3+4 are at 4 lanes? I would like to install 2x 7950 cards to do a BruceX test. Did Mavericks solve that?įrom another thread I created - before I saw this one.

Another concern I have.or maybe not., FCPX/Motion is the only app that supports 'dual'.what will having 'dual' do to my other apps? Some setups can cause major headaches! Trial and error I suppose.į/showthread.php?t=1583723Ĭurious: Having dual GPU's was a big stability NO NO before on the tower.
