SoftFSB with SIS735???

I was looking at the cheap ECS and PcChips mobo using this ddr chipset. Before you all start, I know these aren't the best manufacturers around. But they are cheap, in fact half the price of most other ddr boards!
Any, from most of the reviews I've seen they have said that they are rock stable, but bad for O/C. What I want to know is whether I could use SoftFSB to crank up the heat a little? Cos if you can, then this could be an amazing deal!
