In another project of mine, I've got an A-Trend OPTi-895 1442G v1.3 motherboard.
The closest source of information about it that I could find is here (currently down, wayback link). It mentions v1.2 of the board, but seems to be almost the same.

However, I can't really decode its CPU configuration jumpers. For instance, in CPU speed table it mentions exactly same settings for all and when it says "3 2 1", what does it mean?
Furthermore, that page mentions voltages 3.3 and 5, but currently the board is configured at 3.45V (I can measure 3.48V from the voltage regulator). So it looks like there is some information missing.

Does anyone has similar board who could share some more insight on how to configure this? From quick tests, seems to be a fast board and I've read some good comments about the chipset, but couldn't really find more useful information on how to configure the jumpers. Any help would be greatly appreciated.

Edit:

Actually found more detailed manuals at this location. This motherboard was briefly discussed in another post.
From the manual it seems that the board is configured for 3.3V CPU, but as I've said above, I am reading 3.48V (and the installed CPU is 3.45V). Maybe there is a hidden jumper for this?
