That's a very small prime rib, so best just cook it like a steak. BBQ it on a grill, it it is not done enough for you, finish it in the oven, 325 till internal temp is 125. Let it REST for 20 mins, after heat will raise the temp to about 135 or medium.
Nothing special about this small a cut. Just a real nice steak!
