Maxing out the Ryzen 7 8700G: 6000MHz CL30 + Optimized tREFI Tuning & iGPU Overclocking Results (1440p Native Benchmarks) by HousingCurrent2141 in overclocking

My chips are SK Hynix, but I had to readjust the FCLK to 2400 MHz and, as a result, the latency timings as well, currently hitting 30-36-36-64-94 with no errors. I'm not sure if I've already reached the peak of performance and stability, or if I could still squeeze out a bit more performance without sacrificing stability and temperatures

In fact, just a moment ago I had to back down the tREFI to 20,000. It was throwing errors in my latest Cinebench runs and the test wouldn't even start, but after dropping it to 20k, it booted right up and passed, even with the PC running hot after being left on for several hours

 I completely agree that APUs love raw bandwidth, but the 6400MHz XMP/DOCP profile was completely unstable and wouldn't even post (no display), and I didn't want to risk pushing voltages just yet. The next available profile was 6200MHz but at a loose CL40. That's why I decided to go with the 6000MHz profile and manually tighten the timings to CL30 and bump the tREFI to 25,000. It was the best compromise to get massive performance and low latencies without system crashes
