kn1 SLI lite dual channel ram become single channel

[gohand]

Hi, I recently upgraded my pc's motherboard from ASUS A8N5X to ECS KN1SLI lite Extreme; everything worked fine except 2 things, the original dual channel ram became single channel, which is 2x 1gb of OCZ platium low latency ram I've tried to play with some of the setings in bios and read up on some simular problem in some forums which suggest crank up the ram votage, which don't help either, I tried 3.01 V and i've also updated its bios to the latest. also the second problem is that I tried to tweak around with the CPU frequency, I had it originally OC on my old board cpu is Opteron 165 1.8 @ 2.1 originally, but now the frequency setting almost had no effect on the clock, even if i up from 200 to 300, the clock doesn't change, its like that value is just for show.... any help is greately appreciated.
