I'm able to get some ECC PC100 256 MB RAM from HP. For around 40$. And I have a BX board. So this should work, eh? But are there any speed tradeoffs? Does ECC RAM works beside non-ECC RAM? Can I still activate ECC? Or should I get PC133 no-name RAM for about the same price? I've got a celeron system, so a FSB over 100 MHz doesn't interest me.
