i cannot seem to figure it out i thought it was cause it is the windows 7 premium so i upgraded to pro which says that it supports up to 32 gigs but im only getting 2.96 usable
Pro should do up to something something like 192GB IIRC. 3.96 is just perfect for 32-bit address limit minus 1GB card. Home Premium would still do 16GB.
If you install another OS, such as Ubuntu, what happens?
