I have decarbed buds in the oven at about 220 degrees for I think it was about 20 minutes. I could be wrong on the time. I guess you can go between 220 and 240 degrees for the process. Any higher and you risk damaging some of the more delicate compounds.
I looked all that up on line last year before I did it. I think I wrote a post about it after I did it.
