Just vmod and OCP mod that I've seen, no real need for a memory mod as there's minimal gains anyway. Vmods and OCP (sometimes OVP mods) work together, one raises the voltage and the other moves the over current trip point up and out of the way allowing the use of the higher voltage. Occasionally the only mod needed is the vgpu mod, depends on the VRM architecture and design limits. Both mods should let you OC higher with this particular card.
