High Temperature Reading

[Duallies]

I have an Athlon 64 X2 5200+, and I turned on CoreTemp logging for the night. When I checked the Temperature Readings in the morning, Core #0 was reporting a high temperature of 385F. I checked the logs, and at some point in the night, the recorded High Temperature jumped from 157F to 385F. However, the Core #0 temperature never appear to rise above 157F. I'll paste the CSV from the time of interest. My logging interval is set to 10 seconds. Could this be a bug?

What version of Core Temp are you using?
Try upgrading to the latest one.

I am using CoreTemp Version 0.99.6.1. I believe this is the latest version. I am using the 32-bit version as I am running 32-bit Windows XP.

Were you able to reproduce this problem? From my experience, the A64's DTS sometimes reports incorrect readings.
I wouldn't worry too much about it.
