Dell Specifications state memory will run at 2933 MHz. Intel's specs for your processor state that it uses only DDR4-2933 RAM. Yes, you may install 16 GB (two x 8 GB). Crucial has RAM that they guarantee to be compatible with your system. It is 3200 MHz RAM, but it will downclock (run more slowly) to 2933 MHz in your system.  Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard. (Repeatedly touching a metal case part is not sufficient mitigation with modern components.)
i'm thinking of making my dual channel 8gbs into 16gbs (because you make gaming computers out of potatoes) but im just wondering if my laptop can handle 3200mhz, since the current set is 2933mhz. if it matters, here are the specs - gtx 1650 and an i5-10300h + ssd   (i know my laptops not alienware, just the closest thing to it)
