Abstract: A method and apparatus for analyzing the configuration of a computer main memory. A complex memory controller which imposes restrictions on the memory's configuration, determines whether a configuration is consistent with those restrictions. The results of the determination are then reported to the user, the memory controller assesses a memory configuration's compliance with interleave restrictions, memory row size restrictions, and memory speed restrictions. In addition to reporting restriction non-compliance, the memory controller can also assess and report whether a particular configuration is optimal.
