I have recently changed my FSB/multiplier on my CPU. It used to run at\n133FSB X 16 multi, 1.825vcore for 2.13GHz. Athlon XP1800+ Tbred-B. I had no\nchoice as one of my memory modules (Dual-channel mode) was PC2100 (2 X\n256MB). I now have two PC3200 modules and have changed the settings to\n200FSB X 10.5 for 2.1 GHz and have been able to drop the vcore to 1.80 volts\nand still have it run stably. I see a slight improvement in both CPU and\nmemory scores in PCMark 2002. (It won't do 11X even at 1,850 vcore, the\nhighest setting available to me without pin-mods, I think I have reached the\ncapabilities of my CPU).\n\nHowever, running at 100% (SETI or Prime95) my CPU temp had gone up nearly\n5°C compared with 100% load previously with the CPU running slightly faster\nand with a higher vcore. I find this paradoxical. I have since rectified the\nproblem at the expence of extra fan noise.\n\nWhat would explain this phenomena? Isn't 100% in fact 100%? Would the\n(presumed) faster through-put account for this?\n\nJust curiousity, I actually expected lower CPU (diode) temps, particularly\nas I was able to lower vcore.\n\nThanks for any input.
