Cinebench cares very little about RAM speed/timings (as do most things) and XMP CL16 3200 to XMP CL18 3600 is hardly an upgrade anyway. Most people wouldn't have noticed a difference between CL16 3200 and CL16 3600.
Not to mention if you're setting XMP and calling it a day your motherboard is going to set all secondaries and tertiaries, and your motherboard is going to set them far looser at auto 3600 than auto 3200 to increase compatibility. XMP only sets the primary timings and command rate, the rest is up to your motherboard.
I'd probably return the RAM and spend the money elsewhere if you don't feel like investing the time setting all your timings manually (which even if you do isn't likely to get you huge gains either).
