PC specifications include an MSI PRO B660M-A DDR4 Intel i5 12400 processor, 32GB DDR4 memory at 3600MHz, an RTX 4060 Ti graphics card with 2560x1440 display, and a Seasonic B12 BC 850W power supply. The main issues stemmed from previous hardware: a 7900XT caused frequent shutdowns, the PSU couldn't handle it, and after returning it, the 4060 Ti still experienced similar problems. Before those models, I used a 3060 Ti without issues. All three graphics cards had the same stuttering behavior, suggesting no GPU-related cause. Possible causes point to the PSU possibly being damaged during the 7900XT replacement. The system isn’t performing well overall, even with high FPS in many games. Monitoring data shows GPU usage dropping near zero during stutters, especially in titles like GTA V and PUBG. I’ve tried various fixes—reinstalling drivers, updating OS, turning off G-Sync, adjusting sync settings—but nothing resolves the problem. Could you help? Thank you!
It's interesting to explore different approaches. Setting an FPS cap might help, but I'm unsure if it addresses the main issue. The main worry is the clockiness, which seems to be a recurring problem. An 850W PSU should easily support the 7900XT, as the card only draws under 500W and the CPU stays below 125W. This suggests a power supply issue rather than performance limits. Have you considered using a UPS?
It doesn't make sense at all—everything functioned smoothly before the 3060 Ti a few months back in those games.
I'm glad I could assist. It seems like a UEFI issue, though vBIOS might be more probable. Testing with several cards removes that chance. If you're okay with the GPU using a bit more power while idle, just leave it as is. Otherwise, check for a BIOS update for your motherboard to fix any strange C-state problems.
I'm in the final BIOS upgrade and also tried to resolve the problem. Another question about the C state feature—Windows keeps displaying fluctuating clock speeds, isn't that typical? I assumed C states maintain a consistent frequency.
PCIe C-state relates to the specific PCIe version being used. This technology enables devices to communicate with older versions for efficiency, such as PCIe 1.1, which consumes less power compared to newer standards like PCIe 4.0 or 5.0. You can check this information using tools like GPU-Z, which displays the current PCIe version and its C-states when idle. Performance metrics can change significantly depending on the GPU, such as your RTX 4090 fluctuating between 2400-2700MHz at stock settings and 2900-3050MHz with overclocking. These variations may lead to benchmarking inconsistencies, though they are generally manageable. If the clock speed shifts widely—like from 300MHz to 2000MHz during high power usage—it often indicates a deeper system issue, possibly linked to UEFI, power management, thermal control, or stability problems.
