I'm just wondering if those of you using non-ECC RAM have any stability problems. The SW hardware requirements does not mention using ECC RAM, but it was recommend in an article from 2005 SW World conference from a SW rep. I am considering using a motherboard with either a Intel 965 chipset which does not support ECC RAM or a 975X chipset that will support it. The 975X is on back-order, so I would prefer not to wait for this system if I don't need to.
