Howmany minutes per lb. at what temp for prime rib?? Help...?!

Question: put it in a 475 oven and immediately turn the heat down to 350. 15 - 20 min per pound is a bench mark but I always use a thermometer. You spend too much on a roast to take a chance. 120 is rare, 130 is medium. This sounds low but
temp will go up @5-10 deg once you pull the roast. Always let it rest for @ 20 min before carving. (Just enough time to make the Yorkshire pudding... yum

I always sear it for 20 minutes at 425 degrees (seals in the juices) - then turn it down to 350 - 20 minutes per pound for medium.

I cook it at a constant 325 at 20 minutes per pound for a medium rare.
Don't poke it with a fork it will let the juices out, and then take it out when thermometer reads 140 degrees, let it rest 20 min. or so and by the time it's ready the temperature will be perfect, it cooks after you take it out of the oven.
