Line 43: === RAM Reliability (ECC vs non-ECC) === ECC (Error-Correcting Code) RAM detects and corrects memory errors, improving reliability, while non-ECC cannot. There is ~~significant~~some misinformation about random ~~“cosmic~~cosmic ~~ray”~~ray bit flips. Large field studies show errors are usually caused by physical faults in specific DIMMs (Dual In-line Memory Modules, the removable RAM sticks), not uniform random events. Most DIMMs experience no errors, while a small number produce the vast majority of faults. Modern DDR5 memory also includes on-die correction that silently fixes some errors before they leave the chip. A failing DIMM on a non-ECC system is more likely to cause crashes or obvious corruption than a silent incorrect result. In numerical solvers, bit flips often trigger instability or failure rather than plausible but wrong outputs. For a single TUFLOW workstation, ECC is generally not required solely to protect result quality, though it may be beneficial for servers, critical workloads, or environments operating many machines.
