Mem,
i agree, it gives a good approximation on BIOS with compensated Temp Readings. Your MB is not with compensated readings. I have stressed numerous times that if your chip runs fine, and your temps are within reason, that you have nothing to worry about.
but it is important to know that one ones without compensation, that the temps are at least 6C too low, and often 10C or more too low. This is the same case as with P3-Socket Boards with VIA chipsets. The socket-thermistor reads 13C too on a 7VCA, and doesn't show temp changes.
SO, knowing that the Duron/T-bird runs significantly warmer than a p3, one can surmise that the socket-thermistor on a socket A board is likewise off, at least 6-10C, and sometimes 20+C off.
With Inaccuracy that high, it really doesn't give you an "approximation" of what the cpu is running at. With compensation it is better, but not perfect.
The additional problem is when people with compensated temps and alpha heatsinks see people with taisol's running at much lower temps then they are. Most people dont' know of the compensation in most bios', and assume that their chip is running too hot.
