One major issue with the CUSL/TUSL is, you can't lock the speed
of the PCI/AGP bus. I'm running a P3-S 1.26GHz, and my
Adaptec SCSI cards (2940 and 29160) choke at anything much
over standard 33MHz PCI. Even a relatively small overclock
(e.g. 148 FSB, 37MHz PCI) results in occasional failed boots
and random hard hangs. However, it's completely stable at 140
FSB/35MHz PCI and has been running this way for years. So I
settle for 1.33GHz from a 1.26GHz CPU, instead of 1.4GHz or
higher.
I agree with your opinion about the P3-S. It's a sweet chip.
Memory latency is outrageously small.
