what's your pci latency timer set at?

What do you guys have your latency timers at? Especially those overclocking.

The "latency timer" just says (in multiples of PCI clocks) for how long a device may transfer data in its "turn" before it has to yield to the next one requesting the bus. This is not a timing adjustment!

Yes, I read about it before posting. I understand the basic concept. I was looking for what other people have theirs set to since it was an option in the bios.

I don't see how it's not a timing adjustment if adjusting it changes the time a device has.

Here's a howto I read on it. PCI Latency Timer Howto

Timing adjustments influence the fine tuned relationship between signals on a certain bus. The Latency Timer value doesn't do that. It's just a behavioral thing to balance fairness against throughput.

32 clocks is the standard on Intel chipsets.

No On any chipset, the default is what the BIOS engineer decided it should be.

32 is too short nowadays. SCSI, LAN, and multimedia stuff runs better when it's on 64. This doesn't compromise multi-agent fairness too much either.
