It still won't post with two sticks in dual channel. I don't have a hard disk attached to the board at the moment as I was just trying to do some high DDR2 clock memtest stressing. The voltages and temperatures look fine in the BIOS. The weird thing is when it does its DET_DRAM thing, the voltiminder LEDs simply do not light up. I'm getting a lot of hangs in the BIOS too.
