EP, Re: To paraphrase.
That's precisely what it says. Let's read it together:
My paraphase>>> 1) You must enable the throttle mechanism for the P4 to run within spec.
Intel>>> Thermal Monitor controls the processor temperature by modulating the internal processor core
clocks. The processor clocks are modulated when the TCC is activated. Thermal Monitor uses two
modes to activate the TCC. Automatic mode and On-Demand mode. Automatic mode is required
for the processor to operate within specifications and must first be enabled via BIOS.
Seems pretty clear. In particular, "Automatic mode is required for the processor to operate within specifications..." So, "the processor" means the P4, yes? And "specifications" could reasonably be paraphrased as "spec", yes? I thought so. The only possible quibble you may have is if you think I mean "throttle" instead of "throttle mechanism". I am not asserting the P4 must be at 50% duty cycle to run within spec, rather that the potential for going to 50% duty must exist to run within spec, i.e. you can't disable the throttle and run within spec.
My paraphase>>> 2) Even with an adequate thermal solution, the throttle may kick in during "high load" code.
Intel>>> Processor performance will be decreased by ~50% when the TCC is active (assuming a 50% duty
cycle), however, with a properly designed and characterised thermal solution the TCC most likely
will only be activated briefly when the system is near maximum temperature and during the most
power intensive applications.
Again, seems pretty clear. A slightly longer paraphrase is: "Look we know that having the TCC on kills performance by half, but if you provide a proper heatsink, the TCC should only activate briefly when the die is hot and you're running power intensive code." The clear implication is that even with a proper heatsink, the die *will* get hot enough for this to happen, otherwise, it would read: "however, with a properly designed and characterized thermal solution the TCC should never activate."
Do you dispute either of my two paraphrase claims? Which? Why?
"Not waste any more time," often means, "I've lost the argument."
