I'm wondering if this has any bearing on system stability at higher FSB? I know it would makes sense that if the agp/pci are locked at 66/33 then it should not matter, but I noticed that my system would lock up while I was playing mp3, running my ftp, and running xp cdkey finder benchmark test all at the same time, but when I only did two out of the three I had no problems. I also occassionaly would get the screech of death with my sound card in certain games. I found a link that talks about how the agp latency is set to 248, while the pci latency for sound and network are at 32. He recommends using powerstrip to adjust the latency of the video card so it's not hogging the bus. Anyone have any thoughts on this? Anyone found that pci latency affects overclock?
