mac pro maximun RAM
How much RAM can I use in my MAc Pro?
Mac Pro, Mac OS X (10.6.8)
Which model do you have? The original Mac Pro's limit is 32 GBs. Later models could accommodate much more - upwards of 96 GBs depending on CPU configuration.

Dual quad core Intel Xeon processors.
I did add 64 GB,.. in the Abou this MAc menu it finds 64, but in the activity monitor only shows 32
32 GBs is the maximum for that particular model (8-core.)
Thank you.
Is it possible to change the matherboard to increase the max RAM?
I really need more RAM for the job I want to run.
I really doubt you can change motherboards given their different designs. What are you doing that would require more RAM than 32 GBs?
HOw about if I boot it in 64 bit mode?
Bioinformatics,..DNA sequence analysis,.... in essence making a several hundred million pieces puzzle.
Imagine you take the all the books of the Bible,... ramdonly break all sentences in 2-3 contigous words,... put all of them in a bag mix well and now try to reconstruct the original without looking at a reference, but just looking at the reference.

Nope, the machine can only physically address 32GB even if it physically accepts more.
So for that you need a lot of RAM, a RAM disk too I'd bet. đ
So you need a newer machine that can handle more RAM you can feed it.
EveryMac (http://www.everymac.com/systems/apple/mac_pro/specs/mac-pro-eight-core-2.26-earl y-2009-nehalem-specs.html) cites 64-128 depending on booting mode and OS,... 128 with Linux
Where does it say that?
under standard RAM,... follow the link I posted earlier
look a the table down the page,... in the tech specs tab
Ok, I got it, I had it blocked the first time
*Apple officially supports 32 GB of RAM in this model, but site sponsor OWC first discovered that it is capable of using 64 GB of RAM when booting MacOS X 10.6 "Snow Leopard" in 64-bit mode. Later, OWC bumped this unofficial maximum RAM to 96 GB running Mac OS X 10.6 or 10.7, and yet again to 128 GB, but only when running a 64-bit version of Windows XP or later or Linux. Mac OS X only can support 96 GB of RAM.
There you go 128GB, would make for a **** of a fast machine with a RAM disk. đ
how the RAm disk works?
how do I go about setting that up?
