well I am going to buy an OCZ pc 3200 dual channel kit because they stopped making the ocz ddr 500 vx line. The thing that worries me is that it won't boot with one stick alone in slot #3 or #4 is this normal? Do i have to have both rams in order to be able to use slot #2 and #4. i just don't wanna buy the kit if i won't be able to use it ini dual channel. I am only gonna use the new kit and not my old memory do u think this will give me any problems. when i place the ram in slot #3 or #4 it just has long beeps and three leds light up. It was like this when i 1st got the board so i used slot #2 and then i flashed to 6-23 but yet it still won't boot with memory in slot #3 or #4. Do u think the board is doomed i just got it 2 weeks ago so maybe i can RMA it. thanks for the fast reply and help.
