My PC's GPU and Mem clock constantly jump from 1000mhz (GPU) and 3800Mhz (CPU) to around 400Hmz each. I have issues playing games with frame drops and performance issues. This has been happening on and off for months. I replaced my thermal paste about a year ago when I started having temp issues but my temps seem fine on both GPU and CCPU so not sure what's going on.
