i have 2xAMSN2200 running on a MSI K7D Master bios 1.82
my cpu2 is always 5-7'C higher than cpu1
the BIOS does not report mesurement of vcore2
also, i highlighted in red some differences between the 2 cpu
including the "Model Name, Reported cpu voltage,

Sandra doesn't always provide accurate info - your 2nd CPUs' Vcore is definitely NOT 2.48V...it'd prolly be burning if that was true

As for the difference in temperature are you using the same HSF and thermal compound on both CPUs ?
Also, if you have some case fans, the difference could simply be caused by the position of each CPU in relation to the airflow in your case, IMO.

Is it stable or are you encountering stability problems or anything?

The temp is not that high, the problem is with the heatsink on the north bridge. I changed mine to a ZM-NB32J and now they are within one degree of each other...if you go ahead and order this heatsink keep the old pins from the orginal one as the ones shipped with the ZM do not fit. Also the voltage is miss reported. At that high of voltage the cpu would fry, I think it is a problem with the sensor on the mobo itself.
