It is almost never the motherboard that fails early for us. We use a 'lot' of supermicro. It is things like slow memory (non supermicro), or failed disk (non supermicro) that are the usual problems. Methinks you have a different perspective on the problem than we have seen in reality. Slow memory, may not matter much for most. Things run fine. In fact, most things will run at 100%, but certain heavy HPC workloads might only run at 85% speed, and we can isolate it to a marginal dimm or dimm pair. It's one of those situations that if you aren't measuring it and you don't have a standard, you will never know.

I come from the HP perspective and really don’t do anything of that sort. What do you expect to catch during burn-in? http://serverfault.com/q/518239/13325 However, if you’re using modern HP boxes (Gen8), you can run a diagnostic loop with the built-in Intelligent Provisioning tool (press F10) or just load the current HP Service Pack for ProLiant DVD/ISO (HP SPP). The latter is important because it brings all component firmware up to date and can allow you to run timed tests or a specific number of loops through the installed hardware.

We're an all-Dell shop, though we are also looking at moving to HP sometime soon-ish (leaving us with supporting both Dell and HP). Ideally, we'd love something that can easily be automated and is Linux-based. What tool recommendations do you have? -Mike
