From my own experiments (see
here and
here) I have found ISO1600 to give the optimal signal-to-noise ratio with both my 400D and 1000D at virtually all sub exposure times and at all temperatures. I take LOTS and LOTS of sub exposures and also dither my sub exposures to keep noise in check and provide a further boost to the SNR.
