Always wanted to know if server cpus are of lower base/boost frequencies, compared to HEDT cpus, precisely because they are designed to work 24/7 at 100% load for a decade, while consumer grade cpus have looser reliability requirements and would fail in this regime at a high rate(without overclocking), so they allow for higher frequency, provided that it's not 24/7 100% load.

The conventional explanation is that server cpus are designed for power efficiency and higher frequencies are wasteful/inefficient. But I wonder if reliability is also a factor, since there are applications for high single threaded performance, but even special high-frequency server cpus never come close to consumer-grade ones.
