It's an HP bios, so there's not much you can tinker with. I don't know what you're driving at with memory frequency, but I think you're talking about overclocking stuff (setting cpu cycles and power levels). Either way, doesn't apply here. And no, DDR is a type of ram (that this computer doesn't support), not a mode in bios. Only two ram slots in the compy, too.
