I'm looking for hard numbers involving the Mean Time Between Failure (MTBF) or lifetime that can be expected of the Intel Xeon 5000-series of processors. I'm just looking for stock data (no overclocking, or running at above-average temperatures, or so forth).
I've looked through Intel's official sources (i.e. the processor datasheets) and haven't found any relevant information. I'm wondering if anyone here knows of a source (hopefully reputable) for the data.
