Guys pls help me on this one. My mobo is a gigabyte GA-X48-DQ6 and I put a 4gb DDR2 Corsair XMS2 memory. Now the problem is this, when I check my windows XP system info it only showed there that my RAM is only 2.75gb Why is that? Is there anymore software out there that is free, where I can use to find out the real score? Pls guys help, Im new in this stuff. And I work so hard to invest on my hardware, that I feel I bought a wrong or defective DDR2. I'll give you more details just ask away.
