Well, whenever the new Mac Pro gets released, you can probably do something like this with it:

128GB RAM, 16 cores/32 threads. The CPU's are Intel E5-2690.

So OSX 10.7.3 recognizes >96 GB of RAM? Did you have to hack anything to make that happen or was this a change Apple made recently?

It's a hackintosh, but nothing out of the norm. Just the standard multibeast stuff.

Ok, well I'm pretty sure the board can handle 128 on these 2010 Mac Pros, and so can the CPUs, so if the OS recognizes it...it should work...? I don't think we'll be getting another 2x16 GB sticks to test it, but something to think about.

I would assume it should work fine. 8 sticks of 16GB. This is 16 sticks of 8GB. And it's the default Lion install.

wallysb01 is referring to what is a 96GB limitation when using eight 16GB QR ECC RDIMMs on the 2009-2010 Mac Pros. OS X seems to not recognise the 2nd DIMM in in the first channel. So it seemed logical that there was a 96GB limitation within the OS as 128GB works under Windows and Linux.

However I believe this was only OWC's theory and they don't appear to have tried with 16GB dual-ranked DIMMs or 32GB DIMMs. They may not even have tested it since Lion was released, though you'd think they would have.

Hopefully, when the new Mac Pro is released this all get sorted out.

i heavily doubt that you needed all those cores and threads.... you are barely using 2 of those at the moment :D :D :D

either way.... the current mac pros can have up to 128GB of RAM right now, but yes, it would be nice to see that option on the next mac pros, but expect a high price point, though. 64GB of RAM is expensive as it is from apple, even if no one will never buy or utilize that much RAM :rolleyes: although it would be nice for the next generation of mac pros to officially support 128 gigs of RAM lol.

and then a couple of days after the refresh: someone is gonna come along and find that the new mac pros will support 256 gigs of RAM :rolleyes:

Hopefully they will support more than 128GB as 32GB DIMMs will come down in price and 64GB ones will soon be available and then those also will come down in price.

64GB ones? Computing just gets better and better lol. But then you have to consider when in the future intel will ever make xeons, or even i7s, that will support 64GB DIMMS per slot? And maybe support up to 512GB of ram? Or am I just being to over-ambitious on the latter? :D

Oh I would think any processor that currently supports LR-DIMMS will support them in 64GB capacity. Xeon 5500, 5600 and E5-2600/4600 do. Can already get 768GB with 24x32GB LR-DIMMs.

768GBs you say!? :O who on earth will ever utilise that much RAM, or even have the money to buy it?? Lol. Any processors that can take a terabytes worth of RAM yet? Or is that for ivy bridge or 2013?

I have used, and topped out, cluster nodes running 1 TB of RAM.
