Can I use 2 642L's in Mac Pro 5,1? - I've heard there's problems if I do?

It is possible to use 2 x 642 in a Mac Pro 5.1, make sure the latest RAID management webGUI is installed. In regards to problems that may occur, in a Mac, the BIOS for the RocketRAID controller is not used so it does not matter what BIOS is on each controller. Also each controller is identified with a specific identifier name in the RAID webGUI so you can have identical devices connected to each controller. The RocketRAID 642 is a PCIe x4 controller, which means it has a PCI x4 physical connector. A PCIe x4 physical connector cannot and will not fit into a PCIe x1 physical slot. I hope the information provided is helpful, it was given to me by HighPoint support. It is possible to use 2 x 642 in a Mac Pro 5.1, make sure the latest RAID management webGUI is installed.

They might, but the 1,1 and 2,1 have a slower memory speed than later versions, I bought these for a 1,1 because the speed matched. Check the MHz of the RAM in your MacPro now, then match that to get the best performance, its likely these: http://smile.amazon.com/Komputerbay-PC2-6400F-Buffered-Heatspreaders-PC2-6400/dp/B005HIWDFK/ref=sr_1_3?ie=UTF8&qid=1426168218&sr=8-3&keywords=komputerbay+mac+pro

I don't think so, that mac pro would be too old. I'm a 5.1, 2009 model...and to get the speed from this card you need PCI2 2.0

I believe the model ID on that model is MacPro5,1 in which case yes this memory is compatible with that machine.

If this helps, mine is running on the Mac Pro 1,1 Quad-Core (MA356*/A) and handles Yosemite perfectly.

Greetings: I installed on a Mac Pro (1,1) with Lion 10.7.5. It fried my computer. I would leave it alone, especially after I spoke with a Mac repair type in Oklahoma City. Sorry.

Hi. From what I've researched, this Airport Extreme Card is compatible with all generations of Mac Pro through 2009. My Mac Pro is an Early 2009 model with a 2.66 GHz Quad-Core Intel Xeon. It is easy enough to install once you remove the modules around the area where it will be installed (looking at the inside of the tower, it is just left of center), but it is somewhat difficult to attach the wires unless you have small enough tools. I had to have a local computer repair shop do that part of the installation. It was worth the extra $25. You might find additional installation instructions at www.ifixit.com. :-) Hi.

No it's likely not compatible. Actually caused my Mac to lock up. Check the manual or Google for very specific specs. I ended up going to a microcenter since I couldn't get the specifics and still had to return twice as mine had a max memory limit. So don't use more than the manual specifies. Might want to go local so you can return easily if necessary.

No it will not work in a Mac Pro 2,1. You need to buy one that is specifically made for apple. This is the one with the PC bios. You can flash these versions to work with Mac but its a lot of hassle when you can just buy the correct one.

No. You can replace the two 2G RAM chips in your Mac with two 4G RAM chips (if the model of Mac you have will accept and read a total of 8G of RAM) and you should notice improved speed and absence of hesitation and "spinning beachball." If you replace only one 2G RAM chip with a 4G RAM chip, you won't see a lot of difference from the original(I was told by a Mac technician).

Yes this should work fine. that is the same mac pro I have except I have the 3ghz version.

We're using them on Mac Pro's (non-trashcan) running either Leopard or Snow Leopard. But I've also had it run on others, I would bet money that you'll be fine, they've kept up with the drivers for each new OS as it comes out. (It is strange wording though)

My Mac Pro is the 3,1. This card works well in it. Your Mac Pro is the 4,1. See here:http://www.everymac.com/systems/apple/mac_pro/specs/mac-pro-eight-core-2.26-early-2009-nehalem-specs.htmlI looked at the specs for the 1,1 2,1 3,1 and 4,1 the earlier modes have a slightly older versions of PCIe slots. You and I the same version and it is working for me. If there is some other issue I can not find it. If Apple Core Tech has a decent return policy go for it.

I'm unsure. Check your "About Mac" and see if the specs line up. I do know that you won't get the 1600MHz out of this Corsair RAM...the Mac Pro doesn't support it.

You can run as many as you like providing your Mac has sufficent resources to handle them all. I have a MacPro 12 Core with 48GB or Ram and can easily run three seperate Windows sessions (1 Windows 2008 R2, & 2 Windows 7), (I've never tried more). I also have a Late 2013 Core i7 MBP with 16GB of ram that runs 2 windows sessions (Win 8 and Win 7) no problem.

I have a Mac Pro mid 2010 with a 2 x 2.4 Ghz Quad Core Intel Xeon 1066 Mhz DDR3 ECC and it worked flawlessly in mine. No issues what so ever, snapped right in and the Mac recognized it with zero issues.
