Super stable. Had it since last January. This board has seen 3 cpu's, a celeron 366@550, a celeron 566@952, and currently holds a P3 850@1054. Using PC100 Cas2, running it at 124 cas2. Don't really know what kind of settings you are talking about, is there anything specific in the bios you were wondering about?
I'm all SCSI too so the lack of ata-66 means very little, this is the perfect BX board for me (Other than the lack of multiplier settings, like on Abit's. I could take this thing higher if I had settings between 124 and 133 FSB). BX boards and PC100 ram forever, maybe in a year I'll see about another major upgrade. By then I'll need some DDR ram I'll bet
