Question Games started crashing after installing additional RAM on Laptop

Aug 3, 2020
So i bought a laptop (Lenovo Ideapad s145-14API), I usually use it for mild gaming and AutoCAD/ Sketchup work. I recently thought of upgrading its RAM since it does have one more slot, by the way the slot is DDR4. So i researched what kind of RAM should I buy, i bought a "Kingston 4GB PC4-2400 CL17 260-Pin SODIMM, DDR4". While installing it i noticed that the pins arent aligned so I flipped it backwards then it fits, slotted it then booted up the laptop, showed that i have upgraded from 4 to 8 gigs so i thought its working perfectly, then i booted some of my games about 10-20 mins ingame , it crashed, games that i tried Calibur VI, MuseDash, Osu, The Witcher 3, Valorant, all crashed while it didnt before, i thought my onboard graphics is the problem so tried a bunch things like reinstalling drivers and even resetting windows 10, after a few days i removed the ram figured that it caused the crashing.
So my question is:
  1. Is the RAM i bought faulty.
  2. Is the RAM just not compatible while the slot and the RAM are both DDR4?
  3. Did i install the RAM the wrong way?
  4. In case the RAM i bought is wrong, what kind of RAM should I get?
That was pretty long but thank you for reading this hopefully.:giggle:
