Scumbria: I haven't seen the temperature requirements for P4. Are they doing the same phoney-baloney overclocking thing with P4 that they tried to pull with PIII? The only number I've seen from Intel on the P4 is the maximum case temperature (which is 72ºC). Intel provides specific instructions for measuring Tcase (which is the temperature of the CPU casing). I have not been able to find a max Tj for the P4. -fyo

Scumbria, <Are they doing the same phoney-baloney overclocking thing with P4 that they tried to pull with PIII?> It's not quite as extreme, 72 maximum case temperature probably corresponds to 77 degrees maximum junction temperature, a few degrees better than the PIII. Its obvious, however, that Intel's transistors can't operate anywhere near the 95 degrees that AMD's can. I don't think its a slowdown effect, but probably higher leakage current that kills the noise immunity at higher temperatures. Petz
