P2B said:
I don't know about the A7V, but in the P2B series there were often two
revision levels for a given board - the 'main' revision level printed
between the PCI slots and formatted as 1.xx (sometimes with a trailing
period which was significant), and the 'PCB' revision on a sticker
somewhere and formatted as D0x. As an example, a P2B-DS with a main
revision of 1.06 could have a PCB revision of D01, D02, or D03 - which
is significant because only D03 has a 133Mhz-capable clock chip.
Sorry to add to the confusion...

Here is an example of a revision number. The revision number keeps
track of the "copper pattern" used to make the board. Any time the
conductors are changed, the revision number changes. A revision
number can change artificially, as for example the last A7N8X of
the 1.xx series is electrically similar to the 2.0 version, and
2.0 stickers were placed on the last of the 1.xx boards.

A second number used to track the boards, is the PCBA number. The
letter A stands for Assembly, and at Asus, there will be a "shopping
list" of the components used to fill the board, filed by PCBA number.
From this, Asus can keep track of which stepping of chipset was used,
what FSBs they supported and so on. PCBA changes more frequently than
Revision number, as if there is a shortage and substitution of a
component in the middle of manufacturing, the PCBA number has to be
changed, to keep track of the change. If a field recall is needed for
a product, the PCBA files determine what ranges of serial numbers would
need to be pulled from the market etc.
The PCBA is pictured here:
