There is no doubt in the stability of this board in non-overclocked condition. There're two undocumented bus speed of 125MHz and 133MHz. However, such high bus speed option could result in system instability. My hard disk failed just after I rebooted my system after running the system for a while. I personally prefer ALi Aladdin V chipset since it proved not only to be faster in performance and also runs cooler than VIA MVP3 chipsets.
Jumpers are well organised and easily accessible.
Asustek's P5A is indeed an overclocker choice and is a great performer. I'm planning to get this board as my review reference board for Socket 7 category.
