Problem with gpu overclocking
Problem with gpu overclocking
I'm experiencing difficulties when trying to power off my GPU. After some time while running benchmarks or games (like GTA V), the FPS drops sharply and remains low until I restart the computer. What's unusual is that the GPU core clock stays unchanged despite the FPS drop; only the power consumption changes, dropping from 115-120% TDP to 50-60% TDP. After the drop, GPU usage stays at 100%. Could this be related to my PSU or motherboard since the GPU clocks aren't dropping at all? More testing would be needed. My current specs are: i7-8700K (4.8GHz), GTX 1080 Ti, Corsair CX750 (from a previous PC, could it be the issue?), Asrock Z370 Extreme4 (or possible VRM overheating?), G.Skill Trident Z 3200MHz CL34 2x8GB). I'm cooling with air using an NH-D15 and have two fans blowing on the VRM heatsinks, so it shouldn't be a VRM problem. My CPU and GPU temperatures are around 70°C, which suggests heat isn't the main concern either. Thanks in advance.
When you adjust the GPU clock manually at specific values, you wish to keep it above your set limit. The VRM circuitry will still enforce the assigned speed, but you can check using the default GTX 1080 Ti reference rate (auto boost clock). In gaming, you'll experience maximum and minimum frame rates. On typical hardware, issues mainly stem from software factors—such as BIOS, drivers, or patches. If storage is slow, consider an Optane module for your spindle HDD. For ineffective RAM speed and timing, use the lowest timing setting with the highest MHz option.
It seems your GPU is hitting the temperature limit and then reducing performance, leading to lower frame rates. Please check your GPU temperatures (including the 1080ti model) and share the data here. Thanks!
I agree with 7664stefan, it's always better to OC a GPU with an good aftermarket cooler. Founder edition meh not bueno. Good air circulation in your case and place for your case to breath should be something to consider too.

On normal hardware, issues often stem from software factors like BIOS, drivers, or patches. If storage is slow, consider using an Optane module for your spindle HDD. For RAM, an ineffective speed and timing combination can be resolved by setting the lowest timing and fastest MHz.
