I'm looking at a ASUS P55SP4 motherboard, based on the SiS 5511/5512/5513 chipset. I BELEIVE that it supports parity memory (the earlier SiS chipset does - anyone know for sure?), but I know that it supports EDO. Hence my question. > Having said that, I'm not terribly enamoured of parity memory anyway; what > good does it serve? ECC memory I can understand, but parity? Nehh. Ok, do you know of any good&cheap ECC-supporting motherboards? I'm trying to avoid the cost that comes with the Compaq and HP server lines. I'm trying to build the most stable system possible for the best price. I gather that you don't think that parity memory is helpful to this goal? Systems with parity memory can't do much more than halt when a parity error occurs, right? Am I right in assuming that systems with ECC memory will correct such parity-type errors and keep chugging along? Will FreeBSD work with such motherboards? Thanks for your response!
