Was wondering if unclewebb might be able to give me some input on calibrating RealTemp. I just upgraded/rebuilt my system with a new i5-750 CPU. Installed my Xigmatek HDT-S1283 cooler and noticed a large variation between core temperatures (especially at load w/Prime95). I went so far as removing the heat sink and reapplying my AS5. I'm still showing a 6C deviation between Core 0 and Core 3 (hottest and coolest). I should note I have the CPU overclocked from 2.66Ghz to 4Ghz. Everything is running smooth as silk so far. Just would be nice to make sure my temperatures are accurate.
