Neither had i with my PCI boards so far. :-) But for sure, i've seen crappy PCI boards en masse. It pays off in the end to spend some DM 100 more in a decent board. So far, i think ASUS had only one widely known misfortune (that's been the use of the totally buggy SMC8669F chip on some older Tr*ton boards). Don't forget: the CPUs are getting faster and faster, and in order to be cheap, some vendors tend to operate hard at the border of usability. 10 pF more dead capacitance make can already be very important these days -- this wasn't the case with a 386/sx16. > >You aren't perchance overclocking your CPU? > > Sorry? Would you like to explain what "overclocking" is? Running at more than the designed speed. I.e., if iNtel designed that CPU to run at 100 MHz, but you're operating it at 133 MHz (knowingly or innocently), the picture might also to get various mystic traps. Most Windows users don't immediately suspect hardware problems if they see Yet Another General Protection Fault... so they probably won't even notice this. Alas, it's hard to know the real CPU speed if some dealer was cheating. Read the various horror stories in the c't magazine... ps: No, i don't know how much you're losing by disabling the external cache. OTOH, if your machine is still under warranty, return it if it doesn't work. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
