trx680,
When you mention a whole rib eye (boneless) are you referring to a full 7 bone roast with the bone removed. If so, I've not done one that large, but I have done a 4 bone roast sous vide where the bone had been removed and tied back on much in the same manner that Aldersmoke did.
I removed and reserved the bone, cut the roast in half to better fit a large Cambro container I use for SV, then seasoned and bagged each half and cooked them at 133F 3 days ahead of serving. I don't recall the specifics, but I think that I probably cooked them for around 6. hours. When done, I placed the bags in an ice water bath to chill then moved them to a refrigerator. On the day of service, the bags went back to a water bath with the temp set at 125F for about 3 hours to warm. Just prior to service, I removed the roasts from the bags, reserved the liquids to build a jus, patted the dry, then put them in an oven pre-heated to 500F for 6-7 minutes to sear and build a slight crust. I then removed the roasts, and sliced and served them. Simple perfection!
That said, doing the PR sous vide as I did somewhat mimics, with marginally better results, a process that I've used for at least 15 years when preparing roasts of any nature. With that process, I simply put the seasoned roasts in an oven (or smoker) set at the lowest possible temperature until it reaches the internal temperature I desire. From there, I wrap the roast in HD foil, and let it rest for 30 minutes or so before searing.
In a situation like this, the biggest benefit of doing the roast sous vide is that it allows me to do the cooking at the desired finish internal temperature well ahead of time so that at the time of service there's nothing more to do except hands off finishing in a warm water bath set at a temperature equal to, or slightly less than, the cooking temperature.
No matter how you do it, sous vide, in the oven, smoker, or otherwise, properly (and perfectly) cooking a prime rib, or any other roast, is one of the simplest cooking tasks to be had, but so many people tend to over complicate the issue with any number of meaningless steps.
