Hi Sylvia_intel,
I have tried uninstalling and reinstalling the software IDU v 3.3.6.068 and still the 124 degree readings on "Memory Temperature" and "CPU VR Temperature 1" jump to 124 degrees C intermittently causing IDU to flash an error and the fans to speed up to maximum. I have reset to default bios settings and am using the latest bios v.0590 dated 2013.7.17. I know the memory temperatures are normal because I have the "ambient air temperature" thermocouple on the memory modules.
Any other recommendations? Thanks in advance!
