You seem to have encountered an unexpected issue with your CPU performance. It looks like you followed MSI's instructions closely, but the results didn't match expectations. The benchmarks ran smoothly for others, yet you experienced high temperatures and power draw, which is concerning. Comparing your scores to typical gaming setups, it seems your setup is underperforming relative to what you're seeing online. It might be worth checking your cooling system or considering a different CPU model. If you need further help, let me know!
It's a bit on the higher side, around 1.35 to 1.40 which is typical for a 5GHz rating. I'd aim for 1.40v when using Cache, pushing it closer to 4.9-5GHz+. That voltage doesn't seem too unusual either. The main concern is the v-core limit of most solid coolers available.
i have a 360mm AIO. That high voltage is gonna jump that die up super high though too quickly for any cooler to have any immediate effect.. Super bad design having to go through all the layers.. die, thermal paste, ihs, thermal paste, copper plate, water, tubes, radiator, air..... lol. We need to figure a better way to cool cpu dies.
Probably just a silicon lottery if you're confident about the settings. 200w on a 360 AIO works well. By the way, there aren't 1.3V 5.3 chips available for continuous use, so don't rely on random bench listings. 5.2 AVX 1.35V was in the top 2%, but that was before the 9900ks binning affected the 9900k.
They were likely full of nonsense. The top two percent probably weren’t very reliable.
It's time to move on from the R15. Try Cinebench R20 or R23 for better performance. The latest builds use AVX instructions that the 9900K can handle. You can find them at the links provided. If you need constant availability, staying with all cores at 4.9 GHz might be necessary. With an 8-core processor and hyperthreading, a 2% speed change usually goes unnoticed.
I’d attempt to lower the voltage and observe its reaction to a small LLC adjustment. If temperatures stay stable, I’d consider increasing it further.
