PCI Latency Timer in BIOS?

[wquiles]

What does this do? :confused:

Do I want to change it? If so, to what (mine defaults to 32)?

Could this improve my system's performance? :drool:

The only timing setting I've ever head of from posts is the ram timing.

So far it seems that the majority of people use tight timmings running 5:4 cpu to ram ratio with BH-5, it seems to increase their Front Side Bus for more speed.

I posted this in another thread about Storage/RAID Performance, enjoy the READ (http://www.lostcircuits.com/hdd/hdd5/):D

Sonny,

Excellent - thanks much for the read :attn:

So it seems that I in fact "should" start playing some with this value, right? :confused:

I downloaded HD Tach and here is my READ run on default values for my Maxtor Diamond Plus 60Gb, 7200, 8MB, ATA133:

and here is the one for my RAID 0 with two WD 80GB 7200, 8BM, ATA100 on a Promise TX4000 Raid Card on the PCI bus (66Mhz slot):

What would you recommend I do to improve these scores? :D

I also know that if you're having troubles with sound cards (esp the soundblasters) you should increase the pci latency to 64.

Start playing with the available parameters & keep detailed notes on the performance gains/losses & look out for speed mismatches.
