I purchased an Alienware M18x R1 about 2 months ago. It was from Mercari and the guy said he only checked to see if it booted to BIOS and forgot about most of the other stuff about it, including what model GPU, other than it being dual AMDs and from what he remembered it (he said its been a minute since last use lol) had graphics issues loading games. I planned on restoring the machine (getting newer outer shell, parts etc) and seeing for myself what exactly the issue was with the GPU while pulling them out. So after getting all the stuff i needed, I eventually got to pulling out the GPUs and the cards looked like they were in good shape. Didnt see any noticable damage. Alot of dust which i suspected mightve been the cultprit for the issues. Thermal paste was very hard and dry lol also suspected that. Crossfire cable looked good too. So i took some pics of the GPU itself in hopes that a google image search would tell me the exact model. I got mixed results but i kept seeing the "AMD Radeon 6990m" pop up the most and it did match the dp/n number. So after putting laptop back together, i install windows 10 and downloaded the AMD drivers. One driver was called Catalyst and Radeon Crimson. Keep in mind i know jack about AMD (first experience believe it or not) lol so i downloaded both. I had no issues with the installations as it said there were no issues or wrong model or w/e, but i didnt see any screen flickering like usual with NVIDIA (which im used to) and it installed rather fast. After restarting and checking Device Manager, it still was the Intel HD graphics. I checked BIOS, says nothing, checked GPU-Z and it just shows the intel HD. The only AMD related thing on my start menu is "AMD report wizard". Nothing else AMD related is in my system. So what am i doing wrong here exactly? How do i find out the exact model of this GPU? If its even that? How do i know if they even work? Should I remove the Crossfire cable? Maybe thats it? (Also first experience with Crossfire). Is there some settings checked or unchecked that im unaware of? Im probably going to get the best GPU for this model anyway, but im just checking to see how good this AMD works, (if i even can lol).
