How do I boost my CPU speeds to said "4.9 GHz" a link or youtube video would be helpful...
The boost speed is probably not something you'll be able to maintain in a small laptop. Depending on the bios, there are options for setting the power level durations for PL2, it will boost for that duration. Though the heat and power use is going to be huge, and your laptop won't be able to handle it, except for a very short amount of time, which it is already setup to do. In the end the 4.9 Ghz is a marketing gimmic on a small laptop. But you're free to fiddle. Just be aware that you may hit thermal limits, so keep an eye on that, I believe if your CPU goes over 100 degrees it will shut down, but you should avoid it getting to that point, it's not good for the components, perhaps your cooling pad will help a bit, but I don't see it helping enough.
Not having a GPU is the biggest mistake I made but graphics does not mean a lot to me. As long as I can play and run the game smoothly...
To be honest, if I were to buy a laptop these days, not having a GPU is one thing, but I would definitely make sure it has thunderbolt, so that running an external GPU is possible, I looked up your laptop, and while it has USB type C, it doesn't have thunderbolt unfortunatly.
You mention running the game smoothly, that's a loaded statement. Smoothly isn't actually easy on compromised systems. Smoothly will depend on the game, the settings, and the hardware (both CPU, GPU, Memory, etc..). But in general if you want to run smoothly on an integrated graphics do something like this:
- Lower resolution in the game to the lowest it will go, 720p, perhaps
- Lower all game graphics settings, perhaps use preset 'low'
- Make sure no other applications are running, even go as far as turning off unused services (do a google search, you'll find some guides).
If the game you want to run doesn't run "smoothly" for you using the above procedure, then you're pretty much out of luck.
If it does, then you're in luck, either keep it that way, or start to bring up settings, probably start with graphics presets to medium. You'll notice the biggest improvement to image quality that way. If still "smooth" for you, bump up the resolution somewhat.
And remember, you need to do this on a per game basis, as some games will run more smoothly than others.
Different people call different framerates "smooth", so perhaps 30fps will be fine for you. But even FPS is complicated, and it's usually the changes of frame times that people notice as not being "smooth", hiccups. Those can often be caused by memory bandwidth problems (running single channel, especially with integrated graphics), but can also be caused by a weak CPU, or just the game and how it is optimized and utilizes the GPU.
Good luck!
