TBH I nevr had any problems booting my IP35 Pro with 4 sticks of Crucial (I wanted to see if there were problems and it only takes seconds to fit/unfit RAM). I did go straight to the BIOS and up the voltage to 2.1V though - I didn't want Vista to crash half way through installation!
Don't have a P182 either, let's hope MSIC pops back in. Can't say I've ever had a problem fitting an OD.
