Depends on the deschall code, what OS you're running, how much load you
have on the PC, etc, which all force the data for/from calculations to
be transferred to/from registers, L1, L2, and main memory. The chances
of a CPU failing at the register or L1 level while running at its rated
speed and environment are next to 0. The CPU is a single macrocomponent,
so we can fully expect it to work 100% of the time according to spec.
However, I am less confident about sustained, near maximum-bandwidth
transfers between CPU, L2, and main memory. See my previous, long-winded
message about memory refresh ratings and wait state configs.
