just the normal 65 the 83MH was a bug he couldnt replicate.
You're thinking of the 6800xt, the 6900xt does 87 stock. look at my previous post.
1 video showing 87 and other videos showing 65, on the video that showed 87, the guy got just one time, failed other attempts, must have been a bug or some sort.
