Bios question

[ChrisLandin]

Hi all,

just been rooting about in my bios and I have come across a setting I have no idea what it does or means.

Its called PCi latency timer. It is set to 32 as default but when clicking into the option it has a range of 0 - 255. What does this function do please?

Each device in a computer that is connected to the PCI bus (this includes AGP video cards and other motherboard components such as USB and FireWire devices, as well as add-in PCI devices) has a latency setting of between 0 and 255. These settings are decided either by the device itself or by the operating system, depending on the device. The latency setting can basically be thought of as the "priority" of the device on the bus. The higher the number, the longer the device can block other devices from using the PCI bus during data transfers. Note: It does not affect PCI-e devices.

If it isn't causing you any problems just leave it as it is.

Oh and by the way......Google is your friend!
