Actually, the accuracy spec on the DS2438 temperature is +/- 2. You have to calibrate it to get higher accuracy readings.

I just tried this and it seems the 18S20 on the board agrees pretty well with an external 18B20 daisychained together, as well as with an actual mercury thermometer. It's only the 2438 that reports 1 or 1.5ºC more. It seems I've been getting high readings because I screwed up and used the 2438 reading instead of the 18S20.
