I recently updated my bios from 0703 to 1004 because I got a pair of mushkin xp2-6400 that didnt work and I thought upgrading the bios would help. Apparently one of the sticks is faulty, one of them works perfectly in single channel mode and with the other memtest hangs at start, etc.

Anyway I noticed that the "CPU temp" is now always 5 degrees lower than it was before. The Tcase one, it was usually 33º with normal usage (not totally idle) and now it's down to 28º. The cores still report the same temperatures. From what I read, the bios calibrates the Tcase, but the Tjunctions are already calibrated, which explains what happened. Should I believe the new temp?
