Embodiments of the present invention provide a method and apparatus for optimally mapping a tiled memory surface to two memory channels, operating in an interleaved fashion, maximizing the memory efficiency of the two channels, while maintaining the desired access granularity. The system comprises a tie member anchored in an anchor hole bored into the existing foundation and a tensioned against a base plate and a cover plate seated along the top of the wall. Equalization is then achieved by adjusting the power of each channel as a function of the difference between the channel-specific figure of merit for that channel and the site-specific figure of merit for that channel’s drop site.
