==== Continuity modules ====
[[File:RAMBUS-Terminator.jpg|thumb|upright=1.7|A Rambus continuity RIMM (CRIMM), wrongly known as terminator and also known as dummy]]
The design of many common Rambus memory controllers dictated that memory modules be installed in sets of two. Any remaining open memory slots must be filled with continuity RIMMs (CRIMMs). These modules provide no extra memory and only served to propagate the signal to [[electrical termination|termination resistors]] on the motherboard instead of providing a dead end, where signals would reflect. CRIMMs appear physically similar to regular RIMMs, except that they lack [[integrated circuit]]s (and their heat-spreaders).
