A few months ago I started getting MCEs. Seems to be a malfunctioning memory module. I was wondering how to decode the processor and bank fields.
After reading the accompanied pdf file, i assume that these values are 0-based. On my K8N-DL I assume that processor 0 would have 4 modules with 8 banks, and processor 1 would have 2 modules with 4 banks. With this in mind I find these values confusing. There is no bank 4 on processor 1. Although there is a memory module installed on bank 4 on processor 0. Am I confusing the numbers?
