AFAIK, you see it when the motherboard supports ECC RAM but you only have non-ECC RAM installed - the kernel doesn't even try to load the ECC module unless it detects that the hardware is capable of ECC. I see this warning all the time on my machines (all with AMD CPUs - currently a Phenom II 1090T, an FX-8150 and an FX-8320, and a Threadripper 1950x). As you say, it's not something to worry about unless, of course, you KNOW you paid extra for ECC RAM and it SHOULD be detected :) ECC RAM typically costs at least 30% more than non-ECC RAM and it's typically not available in stock in most whitebox computer shops, it's a special request you have to go out of your way to ask for or find - so, unless you've re-purposed an old server machine, it's not likely to be something that someone has and doesn't know about. > Typically you will only find ECC support on server motherboards, not > comsumer level motherboards. Most AMD motherboards supporting Phenom II, FX or newer CPUs support both ECC and non-ECC RAM. i.e. since at least 2008 or so. Intel motherboards and CPUs typically don't support ECC unless you've bought a "server" motherboard and CPU. Intel likes to engage in artificial market segmentation to prevent customers from using cheaper CPUs and motherboards for what they consider to be high-end server tasks. because near-monopoly allows them to get away with shit like that. craig -- craig sanders <c...@taz.net.au> _______________________________________________ luv-main mailing list luv-main@luv.asn.au https://lists.luv.asn.au/cgi-bin/mailman/listinfo/luv-main
