I have used DDU to unistall my previous card and selected the one where it said “for installing new graphics card”. I also changed out the thermal paste and pads once again. After I did so, the laptop just kept shutting down once I hit the lock screen (on windows). I’m honestly not sure why. But after some time, I ran some games and I noticed that my temps are 10c lower than average. I’ve only seen it shut down once it hit around 88c-91c. I can under clock the card using msi after-burner, but I can’t really change anything else since it wouldn’t let me. I am aware that my gtx 675m is a 100w and the radeon is. 55 watt, but I don’t really have any other working card for this laptop lol. I do have a 330w adapter, but the m17x r2 doesn’t recognize it, and the computer would just run at very low performance and speed. I also ordered a replacement card (a hd 5870) and it ended up being defective. Since I have 2 alienware m18x’s, I decided to just take out the spare gtx 675m and slap it into the m17x r2 (since I don’t have anything else to use).
(Also this m17x r2 laptop is just for a project. I’ve seen people out there putting newer mxm cards in older alienware laptops so I wanted to try it myself)
