Difficulty speaking beyond PCIE Gen 1.
I have an i7-8700, GTX 1070 EVGA SC, everything works fine except for basic window movement which stutters. The issue turns out to be related to PCIe 16x Gen 2/3. Setting it to 1 resolves the problem. The challenge is with games needing high bandwidth that run at very low FPS—like Deathloop at 60% GPU usage and 35 FPS. Switching to a 4X slot lets me enable Gen 3, but Gen 3 4x equals Gen 1 16x, so no real difference. Can I force the mother to run at 8x lanes to test 8x Gen 3? I replaced the mother thinking it was a slot issue, but the new one has the same problem too—so it’s not the hardware fault.
Gen 2 16x matches Gen 3 8x, meaning testing one effectively covers the other. Have you thought about limiting your frame rate with tools like RTSS in MSI Afterburner to ease stuttering? If your system is constrained by CPU power, boosting headroom by setting a comfortable FPS can help lessen strain and reduce lag.
it's not the typical kind of stuttering. changing it to anything other than version 1 causes issues with moving the file explorer window and audio problems.
That is not normal behavior. Since you already tried replacing the motherboard, that sounds like a graphics card issue. It's sounding like something is broken with regards to the way it handles PCIe. I hate to be the bearer of bad news, but it sounds like your card may be dying.
card is working like this for over a year now. i just posted it now. maybe some end pins have issues? thats why i wanted to force 8X, maybe the left side pins are working normally. here's vid on pcie link speed set to Auto in bios everything goes back to normal with pcie gen 1 speed VID_20230501_191949_0_COMPRESSED.mp4
Your video seems bugged - it's only audio. Have you inspected the pins to see if there's any signs of damage or corrosion? While it could be bad pins, it could also be that there's a problem with the interface that is causing the card to have issue when the bandwidth is above a certain level. The fact that the card doesn't have issues at PCIe 1 16x and PCIe 3 4x leads me to believe this is more likely to be the case, because I don't see why (if bad pins alone are the problem) that it wouldn't also have problems at a lower PCIe level.
It might relate to the CPU since the main graphics slot is usually connected there. Alternatively, the PCIe controller on either the CPU or GPU could be malfunctioning. Having someone test your card in another system would help determine if the problem lies with the card itself or the CPU. My opinion leans toward the card being the cause, though the CPU isn't impossible.
Testing the GPU on a different machine, plus another one on your system, is a logical follow-up.
