RAM Upgrade on Thinkpad L490

I have Thinkpad L490 with Ventura installed
I have 8GBx1 RAM and i can expand upto 64GB

Is it safe to install 32GBx2 RAM ?
Do i have to reinstall OS ? (maybe a very dumb question , but hey i am using a hackintosh )

What kind of performance boost should I expect on this laptop using iGPU ?
