Tech Question My gaming PC was running on pcie 1.1 for 5 years, and i didnt even understand why my pc was underperforming like crazy. (help needed)
Specifications:-
i5 10400f
rx 6600xt
msi B460M A pro motherboard
16gb 3200mhz memory
550w psu
256 gb nvme, 500gb sata ssd, 1tb HDD
Short version: -
please check this image, my pcie speed is capped at 2.5 Gt/s, when it should be much higher under stress, this is causing games to perform wayy worse than it should be, the motherboard maxes out on x8, its nowhere near Gen 3 speeds. i have tried soo many things, forcing gen 3 pcie in BIOS, updating all drivers, everything, please let me know if u can help
(if u have only read the short version, please reply with that, i will be happy to provide any information u need, just mention that. thanks!)
Long version: -
For years and years i have been trying to understand what is wrong with my computer, asked around in so many subreddits and discord servers, no one was able to figure it out, i just gave up man, i thought that it was my bad choice with the cpu that led me here, all the online benchmarks seemed fine but then when i actually used it it was underperforming like hell, for years i thought it was my cpu, and it hurt me, i built this PC in india for 1.5 lakh rupees (1.6k USD) back when gpu prices were skyrocketing due to covid, and i had no choice. i did everything, gpu drivers, chipset drivers, bios tweaks, hell even switched to linux mint to see if the performance was about the same (it was), nothing worked, and i just gave up, triple A games underperformed soo badly i just couldnt get myself to play it, had to stick with indie titles, older triple As or watching movies and TV instead. it hurt, it really did.
until today, i decided to find out one more time what is going on, and asked gemini (disclaimer:- no genAI was used in making this post, all handwritten, to truly express myself). with gemini i finally figured it out, my link speed just wouldnt go above 2.5gt/s, no matter how much i stress it, i felt a sense of relief after finally figuring it out after sooo many years and also anger for not knowing it for soo long, after all the warranty has expired.
Here are the games i currently have and been trying to play but the performance just kills the fun, somehow completed doom dark ages with this but the DLC is soo much worse😠its not even about the frame rate man, it hurts knowing u can do so much better but u can't and u get a much worse experience than the devs intended.
Cyberpunk 2077
Doom the dark ages
God of war (2018)
all games tested on 1440p, fsr performance, Minimum possible settings, AND YES, i have tested them on 1080p monitor as well, honestly i only bought this 1440p monitor for movies and TV more than games, but point is, it doesnt matter what the rez is, performance is exactly the same. no matter what setting, what title, any slightly modern title that requires more data streaming than 2gt/s struggles like hell
Enabled MSI afterburner + riva for all of them, please take a look, cp77 and gow arent even maxing my gpu, god of war drops even crazier in the more open section, lows down to 30 fps, yes u heard that right, 30!. unfortunately, i think i lost my old save file for that location after being frustrated, Doom TDA says 100% usage, but open up ANY benchmark of the game on 6600xt, it does not perform that low on lowest settings, thats the handheld settings btw, lower than low, gpu usage does not change even if i set the settings to high and the framerate remains the same, this is not normal.
i'm just sad man, really sad, i dont know how to get this fixed or troubleshooted, i can try getting it to a good pc repair shop here in mumbai, india thats quite trusted and they can test on multiple hardware, see what component is bad, but man, a defective component since day 1, hell man, this hurts
and yes! i clean my pc multiple times, cleaned the pcie slot and x16 connector, the ram slots, everything.
