Interesting method for calibrating the CPU diode courtesy of arctic silver-

I had already artifically changed the calibration of the diode on my DFI MB as it read 11.C lower than the socket temperature( hardly believable). I found by adding a 20.C offset in MBM5 it gave readings that were believable.
I just used the calibration method above changing my CPU Mhz from 2511 down to 1537 Mhz and found the temp ratio was out by 1.C- so upped the offset to 21.C and now all is fine.
Detail
CPU ratio =2511/1537= 1.633
Temp ratio= (47.c -17.C)/35.C -17.C)=30/18= 1.66
Not far out but adding 1.C to the diode temps gives a ratio of 31/19= 1.631
I used CPU burn-in to load the CPU.
