The following processors are in question, Processors 735, 745, 755, 780. Other than the FSB and clock speed. Is there one in this set which has, in your opinion seemed to be a more reliable chip than the rest.

As long as you don't overclock or undervolt, I don't see how any of them can be unreliable.

As Sugo said, as long as you don't try to undervolt, overclock, and then stress them, they are all extremely reliable.

For just about all CPUs made in modern fabs, they either work when they get tested or plugged in....or they don't; it is really rare to ever get a CPU that only "half works" or "works half of the time."

Hmm, does anyone care to elaborate on how undervolting *might* have a negative effect on the reliability on the long or short run?

Based upon what I know about memory systems, undervolting will not physically damage the processor, it just may cause the system to become more unstable and open to mis-processing. Undervolting is typically done to reduce the operating speed, and therefore, temperature and power consumption of the CPU. One could say that it will even lengthen your CPUs lifespan because of the reduced temperatures.

Yes, but the downside is that it can introduce instabilities, especially when running many floating point calculations; it is best to stress test the CPU anytime you undervolt it and plan to use it for any period of time.
