Baking potato gratin AND ham?

I have a gratin recipe (90min at 325F) and am heating up a 6lb boneless ham (about 2hrs at 300F). Do I need to increase the oven temp because I am cooking both together?

You can cook both at 325F, the ham might cook a little bit quicker, but I always feel it's better to cook at a higher temp, especially when you have two things in your oven, depending on its size. In this case, since the gratin is supposed to cook at 325F, just use that.
