ML350 G5 Memory

I'm going to be upgrading the memory of my server from 4gig to 8gig. (PC2-5300 ECC 240 pin). Currently the server has 8 sticks of 512mb RAM (4GIG total / all memory banks are occupied). The 'new' 8gig memory will be 2 - 4gig sticks (8gig total). With this 'setup' 6 memory banks will be 'empty'.
Questions:
. Does the 6 empty memory banks need 'dummy' memory sticks?
. Should the 8gig of memory occupy 'all' 8 memory banks?
I can not find any documentation on this memory upgrade other than the system can handle a total of 32gig.

The purpose of the memory upgrade is to install VMWare AND Windows 2008. (System currently has MS Windows 2003 R2 Standard and will be kept).

Current ML350 G5 setup:
. 2 - Dual core 3.0 processors
. Raid 5 setup
4 - 160gig of Dasd
3 - active
1 - spare
. MS Windows 2003 R2 Standard
. 4gig of Ram

No.

No.
You can also take out only two 512mb sticks to install the two 4gb stick and leave the remaining six 512mb stick in. This way you will have 11gb total memory.

These are three examples only. Many other memory combinations are possible.
Ensure that the two 4gb sticks are installed in slots 1A and 5A.
