Carl,

Are you really suggesting that an RDRAM heat spreader temperature of 37C is a problem? At human body temperature it will not even feel hot to the touch.

As for drawing any conclusions from the SDRAM running 3 deg C cooler, I don't think that is possible.

You pointed out that the ambient temperature was not quoted, so concluding anything about relative power consumptions is impossible.

Another point is that the thermistor was relatively large and had fairly thick connecting wires. The thermal loading due to the thermistor will have had a greater effect on the SDRAM plastic package than on the aluminium heat spreader, so causing a larger under-reading for the SDRAM than the DRDRAM.

Measuring device temperatures in this kind of situation is not straightforward.
