To run 20 Loops in 10GB size will take about 30 minutes. The most of instability for me was the memory. I ran memtest when I built my computer and assume it was stable as it had XMP. Linpack can spit out miscalculations for all sorts of issues such as hyperthreading mishandling, cache error and memory. Some of these errors are not critical, but I am learning that MSFS is very sensitive to memory handling.
