Over speeding

Hey I got a question when I’m flying to my destination and usually I get the overspending signal at 350 knots when I am 32,000 ft and I’m flying a Boeing 777-200ER and after the 32,000 it converts into Mach speed about 0.88 how can I change to go faster. I am a grade one.

Don’t go faster; slow down. You don’t cruise at more than m.85ish in the triple 7 which equates to 320ias below FL280. Slow down and you may experience the wonder of not getting lots of violations.
