Text: commands should be used for transfers that are not CL-aligned and cross the CL boundary. A single snoop is performed on the host bus for MR. Snoop ahead is performed for MRM and MRL and a complete CL is read from , recommended to use MRM or MRL since snoop ahead would provide better overall bandwidth and data streaming , bandwidth is wasted due to the overhead of snoop aheads, and memory efficiency is lowered since a portion , snoop bandwidth. 2.
