Abstract: : Disable the Snoop Ahead function for SMBA systems, or non-SMBA systems that do not satisfy the conditions listed above. Disabling the Snoop Ahead function will prevent this erratum from occurring. Disabling Snoop Ahead affects PCI-to-memory bandwidth, there is no performance impact to commonly run benchmarks or desk top applications. Note: in a non-SMBA system with Snoop Ahead enabled this erratum has not , arbiter policy changes when the Snoop Ahead function is disabled, the following bits need to be set as ... Intel

U115 snoop ahead intel DOC 82439HX 430HX TEXT
datasheet frame
Abstract: 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. PCI Addressing Non-CL aligned data transfers result in lower bandwidth since ... Intel
