I use a HWInfo64 with RivaTuner and AIDA64 for Save LOG on Disk, but i discovery a weird bug on AIDA64, this error i think is caused if you use HWInfo64 with AIDA64.
Look a LOG generated by AIDA64 running with HWInfo64, Sensor inform a wrong CPU Clock's and FSB.
After various test's, changing Power Energy Control profile of Windows, i noted this BUG of AIDA64 Sensor LOG wont appear, if you close HWInfo64.There may be some kind of interference between the two, preventing both from operating simultaneously. Unfortunately the use of HWinfo64 is necessary ATM, as it works very well
