Im pretty sure this question gets asked all the time.... anyways. i recently bought a 1gb stick. Now i have 3gb (2x 1gb and 2x 512mb). The two 1gn are in dual channel as well as the 512 sticks. Right on the board says DIMM 1 and 3 are side by side and the same for 2 and 4. My computer and windows won't detect the 3rd gb but cpuz does. I have updated my bios to the most recent but no luck. I checked the manual but no luck. Im out of ideas. Anyone know whats the issue is? I have a machspeed mk8-939a. with a AMD Athlon 3000+.
i should also add that when i take both of the 512sticks out, it stays at 2gb. I heard that other hardware like the video card can take some of the physical memory.
