Brave, yes, ECC memory DIMMS are cheap (only 1/8 costlier in chip cost), but the hardware platform which will use ECC correction/detection is not cheap. For example, Intel disables ECC support in all memory controllers in desktop CPUs, like Core2, i3/i5/i7. Only Xeons have the ECC circuits enabled. Not sure about AMD.
