Dual Channel success with BIOS rev. 1005?

[Howie]

I currently have three sticks of 256mb PC3200 DDR400 memory installed
in my A7N8X Deluxe board. I have been running with this setup for
several months, ignorant to the possibility of achieving dual channel
capability with a small reconfiguration.

I now realize I can pull one of the sticks (from either Slot 1 or 2)
and the motherboard will default to this capability. Problem is, I
would then only have 512mb of total RAM and with all the multi-tasking
I perform, I really need double that amount.

So, I could trade in my memory and buy 2 sticks of 512mb... this is
cost prohibitive, so I wonder if the following strategy would work?

-- Uninstall one of the 256mb sticks and substitute with a 512mb,
ensuring the 256mb sticks occupy Slots 1 and 2 and the 512mb stick
occupies Slot 3. If I understand how this is supposed to work, I
would then have equal amounts on both channels (Slot 1 and 2 = one
channel and Slot 3 = the second channel)?

Assuming this will allow me to upgrade to 1gb of RAM while achieving
dual channel success (and being more cost effective), I would ask if
others have accomplished this with a BIOS of 1005 or below? I read an
earlier post suggesting it required BIOS 1008 or higher for the board
to recognize the "mixed size" solution. Is this a valid requirement?
I hesitate to reflash my BIOS unless absolutely necessary!

Thanks in advance for answering my questions as well as any additional
insight which might help...

Go for 2x 512 in dual mode.
Slot 1 and 3 or 2 and 3.
Does you cpu run on 333 bus?

My CPU... 2500+ Barton, overclocked to 3200+, runs on the 400 bus...
the board is PCB 2.0+...

Thanks,

Howie
