    The Quad-Core Module (QCM) is based on the well-known POWER5 Dual-Core Module (DCM) technology. The dual-core POWER5 chip and the dual-core POWER5+ chip are packaged with the L3 cache chip into a cost-effective DCM package. The QCM is a package that enables entry-level and midrange IBM System p5 servers to achieve additional processing density without increasing the footprint.
