Best cat litter for odor control?

My boyfriend and I got a cat just over a week ago from the humane society.

He has the smelliest poops I’ve ever encountered with a cat. Vet says he’s fine. I come home and just after 1 day of cleaning the litter, there are 7 whole turds in the box.—I was like “really? I don’t feed you THAT much. C’mon.”—

In addition to changing it more often, I need a better litter. Something to deal with the smell better. Any ideas? I’m using the Arm and Hammer brand and no real luck.
