I am using two 512 meg sticks of Corsair XMS PC3500 in my A7N8X-DLX and running dual channel mode. In order to stay in dual channel mode I cannot put a stick of memory in the middle slot, correct? If I want to increase memory and stay with dual channel mode I must leave the middle slot empty?

Nope.
The ideal situation is the same amount of RAM in bank 0 (slots 1 and 2) as in bank 1 (slot 3), but even with differing quantities, you'll get dual channel.

That was kind of confusing. With 2 equal amount modules, put them in sockets 1 and 3. Add the combined total of the previous 2 to the middle slot later if you need it. That wasn't really much clearer :)

Or correct... that would give you three times the amount in bank 0 as in bank 1...

With only 3 slots how could one bank be 3 times the amount of the other? We should combine the 2 previous in bank 0 and add to bank one. This is giving me a headache Page 14 of the A7N8X-Deluxe maual. " NOTE: To enhance system performance, utilize dual-channel feature when installing addidtional DIMMS. You may install the DIMMS in the following sequence: Sockets 1 and 3 or Sockets 2 and 3 or sockets 1, 2 and 3."

You can run dual-channel using 3 sticks of memory. I'm running a 512 stick in slot 1 and 256 sticks in slots 2&3. Below is a lengthy bit copied from the XHardware forum on the subject.
By user bdubya:
3 sticks work as well however there is one drawback: you have 3 slots for 2 channels. slot 1&2 = channel 1 slot 3 = channel 2
if the amount of memory in one channel is bigger then in the other channel, only the amount of memory in teh smaller channel times two is run in twinbank mode (128bit). the remaining ram is run in 64bit mode.
example: slot 1&2 have a 512MB module in each slot: channel 1 = 1024 MB slot 3 has a 512MB module as well: channel 2 = 512MB
channel 2 has only 512mb of ram *2 = 1024 in 128bit mode, the remaing 512mb of channel 1 are run in 64 bit.
example 2 slot 1&2 have a 128MB module in each slot: channel 1 = 256 MB slot 3 has a 512MB module : channel 2 = 512MB
channel 1 has only 256mb of ram *2 = 512 in 128bit mode, the remaing 256mb of channel 2 are run in 64 bit.
example 3: slot 1&2 have a 256MB module in each slot: channel 1 = 512 MB slot 3 has a 512MB module: channel 2 = 512MB
channel 2 and channel 1 have the same amount of memory so the whole ram is in 128bit mode.
example 4 slot 1 has a 512MB module, slot 2 is empty channel 1 = 512MB slot 3 has a 512MB module: channel 2 = 512MB
channel 2 and channel 1 have the same amount of memory (1GB) so the whole ram is in 128bit mode.

"This flexibility allows the users to populate up to three asymmetric DIMMs in any organization, size and speed. DualDDR simply adjust to the lowest common density that will facilitate 128-bit bandwidth, allowing a wide variety of different DIMM combinations to operate reliably regardless of the individual density and latency characteristics."
Which says that you can use any 2 or 3 dimms, with at least 1 in each bank and you'll get dual channel on twice the minimum amount of memory in each bank.
Since bank 1 (slot 3) will have 512MB and bank 0 (slots 1 and 2) will have 2x512MB, thats dual channel on 512MB*2 = 1GB.
