MOTHERBOARD: 785gm-e65 processor: AMD Athlon II X3 435 Rana 2.9GHz TL;DR: how do i test temp with the core temps disabled, is amd overdrive good for a stress test or is something better? ok first things first! when i changed the bios setting "CPU active core control" (not yet changeing the "core activation" setting ) i saved and exited bios, my monitor then went black and eventually went to sleep because it wasnt getting any signal. i didnt want to just turn the computer off, so i waited like 5 minutes, but with it not doing anything i eventually turned it off. when i turned it back on the monitor still got no signal and again nothing happened. (i was s#itting bricks at this point lol) so i took the side off my tower, and seen the blue off switch on my PSU and decided to switch it off then back on. after that i tried my computer and it turned on with out a hitch...wtf happened??? (i dont know what i planned to do with my panel off the tower lol) ok anyways, so after that little scare i restarted into bios and turned on the 4th core. i only booted up long enough to ensure that the core indeed was enabled, then i booted back down and disabled it. so now that i know i can do it, i have a few questions, and concerns i know i need to monitor their temps, and i have amd overdrive that i can watch the temps that dont get disabled. but i dont know what is what, its showing me 4 diff temps besides the CPU ones, which sit at about 23C. they are labeled TMPIN1,2,3, and 4 and the temps are (in that same order and give or take) 37, 128(which never changes), 29, -293.4 (all temps are gived at idle speed) also what is an unsafe temp? i also know i need to run a stress test on it, is amd overdrive ok or is there something better? and what is the diff between a cpu test and an fpu test? do i run both? do i test all cores or just the 4th? and for how long? any other info you think i should know is aprecaiated, thanks!
