Issue with CPU benchmark execution.
Issue with CPU benchmark execution.
I own an i9 9900 non K model. When using benchmark tools like cinebench, tests begin at 4.6 GHz on the multi-core but drop below boost speeds—around 3.4 GHz—while keeping CPU temps near 50°C. I’ve consulted MSI Afterburner during Cyberpunk runs; CPU stays between 4.2 and 4.4 GHz with temperatures in the high 60s or low 70s, which seems to let games run smoothly. I’m puzzled why benchmarking is behaving differently.
I don't have a motherboard or Cinebench scores. Could you provide those details?
The turbo power caps are configured in the BIOS settings. Non-K CPUs come with a 65W TDP rating, and at the default setting of 65W they tend to throttle excessively under heavy load. Use HWiNFO64 to monitor the throttling reasons. Adjusting both limits can boost full-load performance up to 200W or 250W.
Open the BIOS and navigate to the OC Tweaker, CPU Configuration section. Scroll down until you locate the Long Duration Power Limit and the Short Duration Power Limit. It seems your long PL1 setting is likely at the default of 65W. You should raise both limits considerably to achieve stable full-load performance.
It's failing due to excessive power usage at 140, so I'll attempt to reduce it and check the results.
Ok so set the limits to 128 and it seems to be fine but I do not reach the maximum turbo of 4.6 ghz on all the cores, only get to 4.4 ghz but it still crashes. Wondering now if there is an issue with my cpu.
The image indicates Power Limit Throttling. Full performance isn't achieved when power settings are too restrictive. Your system may be failing because the CPU voltage isn't configured properly or the motherboard can't supply sufficient power. This explains why higher-end Z series boards are preferred.
The article explains that increasing the power limit to a very high setting in the UEFI BIOS leads to a stable long-term all-core Turbo speed of around 4.6GHz with a 1.28V core voltage, while the CPU draws about 160 watts. Since your CPU is set to auto, you should choose the fixed option and set the core voltage to 1.28 to achieve this stability.
I believe the problem lies in the VRM overheating during high-frequency operation, leading to crashes. I also notice a clicking noise from the motherboard and freezing after performing the stress test with increased power limits.
