Hello, I'll try to keep it short and give you a timeline in what happened:
ps: only thing I did that could result in any kind of damage is I used canned air on the fans when I cleaned the laptop and I just let it rip because I didn't know it was bad. I don't think this is relevant but who knows.
- 07.2020: I got a new laptop (used but it was in brand new condition, irrelevant info tbh) and the first thing I did was to go out and buy 2x16gb identical ram sticks (wasn't a 2 stick bundle). Installed them, everything worked good, no problem.
- 12.2020: Cyberpunk came out and I wanted to play.. and to my surpsire the game constantly crashed, even got one blue screen. I brushed it of as the games fault. But now comes the fun part: when I first got the computer I played a lot of Apex Legends, sometimes 8 hours a day but I stopped playing for a bit. Right after the Cyberpunk incident I got back to it again and the game simply just closed after 15mins. No error, nothing. Same in Star Wars Battlefront 2.
- If I use the 2 identical 16gb ram sticks, games crash (not all of them, Apex, Battlefront 2, Cyberpunk does, but Minecraft and League doesn't for example)
- memtest shows an error, doesn't matter if new ram1 is in slot 1 or 2 etc
- If I mix one new stick with the one that came with the laptop everything works, no errors nothing (I've been using my laptop since december like this) the only thing that's different is the mixed memory only runs at 2400mhz and the matching ones run at 2666
- Every ram combination works without memtest error as long as I'm mixing. I tired old ram + new ram 1 / old ram +new ram 2 /old ram in slot 1 /old ram in slot 2 etc... you get the point. As soon as the new rams are together it's rip, but both of them work separately
ps: only thing I did that could result in any kind of damage is I used canned air on the fans when I cleaned the laptop and I just let it rip because I didn't know it was bad. I don't think this is relevant but who knows.
