Well we got these cool new laptops for school with 8GB of 1333mhz RAM n shit. AV school.
But they have 32 bit versions of win7.... When i asked our so called tech support why. He said that its because: "We've been having some problems with drivers on 64 bit windows before".
So they select a laptop with 8GB RAM, And the 5GB of it just sits in the laptop untouched. Nice.
