Digital_Fuzion I have a PCI Latency Timer Question. Is it better to set the PCI Bus Clock higher or lower? My motherboard supports 32 all the way up to 248 in addition to PCI-E Gen3 technology. What do you all think? There's no real reason to adjust this unless you're using a device that demands a huge amount of bandwidth. Increasing it can.. The PCI Local Bus Specification, Revision 2.2, has this to say: (in section 6.2.4, Miscellaneous Registers) Latency Timer. This register specifies, in units of PCI bus clocks, the value of the Latency Timer for this PCI bus master (refer to section 3.5.).
PCI Latency Timer: This item controls how long each PCI device can hold the bus before another takes over. When set to higher values, every PCI device can conduct transactions for a longer time and thus improve the effective PCI bandwidth. For better PCI performance, you should set the item to higher values. settings range from 32 to 248 at a.. "PCI Latency Timer Controls how long each PCI device can hold the bus before another takes over. When set to higher values, every PCI device can conduct transactions for a longer time and thus improve the effective PCI bandwidth." I can not do anything more than speculate at this point.
