I have a presario F572US and I placed an order for a 2GB stick of corsair memory for it, only to discover a day later that my laptop has 2 memory slots (originally occupied by 2x512MB sticks) that support "up to" 1GB each for a total of 2GB total memory. When i got the RAM today from newegg, i popped it in just to see what happens, and viola, Vista detects every bit of the 2GB. Now i have 2.5GB of RAM (left one of the 512's in there). I checked it with CPUZ, and DXDIAG, and they all show the full 2.5GB.
Is it really true that I'm using the full 2.5, or does it just say that, and actually use less?
