Its perfectly safe to try, It will likely do better than 2400mhz. All it will do if you choose a setting too high is fail to boot or cause instability, both can be solved by just reversing what you did to cause it. You wont permanently damage RAM by changing the speed and timings.
That looks like HyniX IC RAM which is not normally what I would recommend for ryzen if you want the best memory speeds but it will work perfectly fine, most hynix ram will tap out around 2933mhz CL17 or thereabouts.
To OC the RAM first I would enable XMP or I believe its called DOCP on ryzern systems in the bios. This will set the ram to run at its advertised speeds of 3000mhz CL16 1.35v. After your turn on DOCP restart the pc and see if it boots, I doubt it will but you have to start somewhere. If it does not boot either wait for it to fail and it should restart and enter the bios automatically if it does not do a hard shutdown and turn it back on and go into the bios. Then start gradually lowering the memory speed until it boots. Then you may want to run something like Memtest86 to verify the ram is stable and you are good to go.
You can play with timings as well, but its a bit more complicated. On ryzen speed generally provides a larger performance boost than lower timings, so you can raise the timings to hopefully allow for stable faster speeds.
EDIT: Forgot to mention to update the bios as said above, that is a good idea before you start OCing the RAM. If you dont know how to update the bios its in your mobo's manual, follow it STEP BY STEP you dont want to screw up a bios update.
