Ram only works with one stick installed or two different sticks installed
My parents had an old emachines t5254 in their closet so i took it home to use just for web browsing when i discovered the power supply and motherboard were toast. I got a PS from a friend and bought a GeFORCE6100SM-M motherboard with Dual Channel DDR2 800 memory for cheap and threw it all together. Then i hit my problem, the two sticks of ram (2x 1gb) from the old mb wouldn't work together on the new one. Only one stick would work at a time. So i bought a 4gb set (2x2gb) thinking a newer set would work and nope it still only worked with one stick. The weird thing is, I installed one of the new 2gb sticks and one of the old 1gb sticks and it works just fine like that. If anyone has any clue as to why it's like that and can help i would deeply appreciate it!
