Yes, I currently have a laptop with this, and you can use MSI Afterburner to overclock it to 1000 Mhz from 700.
You just need to go into settings and check the box "Extend official overclocking limits".
And it works very well. I went from 30 fps in ROBLOX to 60 with pretty good graphics.
I'll attach some screenshots.
(Setting to be able to overclock that high)
I hope this helps!
