which model Presario C700 do you have?  https://www.crucial.com/usa/en/upgrades/hp---compaq/presario-c700-series

 

Also, when you have the 1×2GB with an 1×1GB memory configuration, does the bios read 3 GB?

Officially 2 gigs is the maximum memory on that model series but it will run 3 gigs OK. You are seeing a limit in the capabilty of the chipset and BIOS. It will not run 4 GB of memory.
