AM1640-U1401A Motherboard

I have an older Acer AM1640-U1401A that I am trying to upgrade. Rather than buy a new machine, I am wanting to put in some new memory and upgrade the processor. I can probably do this quite cheap, considering the age of it. I cannot find a manual for the motherboard ANYWHERE online. I don't even know who makes it. I want to check to make sure I don't buy a new processor that isn't compatible. I also cannot seem to find any model number on the motherboard itself.


Does anybody know what processors will and won't work in it? I know it has an lga755 chipset and is currently a dual core 1.8 GHz (from what I can find online). What is the best processor that this motherboard will support? I found many with MUCH higher specs for only like $20 or $30 on Amazon (cheap upgrade), but I need to know that I am buying something compatible.
