Mac Pro Memory Limit

[rsamms]

Hi, I'm in the process of upgrading the memory on my 1st gen Mac Pro. (2 x 3.0 Ghz Xeon). Apple publishes a memory max of 16GB., but I have seen references to these machines running more. My question is , has anyone successfully run larger configurations of memory, and will these systems recognize 4GB modules ?

Thanks,

Robin

32GB works. No chips larger than 4GB exist, but there should be no reason that 64GB wouldn't work, either.
