Exact situation is this:
My A7V333 has been reading the RAM as 768 MB for ages. After recently getting a new 1 GB stick, I realised/remembered that it had two 512 MB sticks rather the 512/256 combination.
now it will not show anything past 1 GB no matter how they are installed. It does show a single 512 stick correctly.
Starting to wonder if the bios is somehow involved. I last upgraded this bios 4-5 years back (if memory serves)and have no desire to now. My other thoughts are this fine MB is getting old and creaky before its time like its owner
