Since the first channel is not populated the server must be running in advanced ECC mode. You can populate DIMMs in slots 8,9 on both sides. You should be able to put 8GB or larger DIMMs in those slots to accomplish the task of adding 32GB of memory.
There are two main concerns with expanding the memory. If the 4GB DIMMs you have installed currently are Unregistered/Unbuffered DIMMs then you can't do it. Also, you may run into population issues if the DIMMs you add in are quad rank. If your current DIMMs are registered and the DIMMs you add are single or dual rank then you shouldn't have any problems.

No, you can mix memory within a channel. You can put DIMMs of a different size in slots 8,9.

Page 31 explains the memory population rules.

Hello Daniel,
the 4GB Dimms installed are RDIMM http://www.memoryamerica.com/hmt351r7bfr8a-h9.html
So I can install 8GB DIMMs from what I understood.
My doubt is, is it a mandatory fact that the 3 channels per processor have the same DIMM size? or this depends on the memory mode selected?
