Processing at standard performance level
Your CPU has unexpectedly dropped to 1.2 GHz, as shown in Task Manager, BIOS, and XTU. You've already adjusted the Intel PMM start balance but haven't seen improvement. The power plan is set to Performance, and you're using an Alienware Area 51 R5 with an Intel Core i7-9800X at 3.80 GHz. Have you checked for overheating, BIOS updates, or possible thermal throttling?
In the registry, reset the Intel PPMC start value to its original setting (3 or whatever it was). In Power Options, click the Restore plan defaults button. Leave Intel XTU open and attempt to run ThrottleStop instead; don’t run both at once. https://www.techpowerup.com/download/tec...ottlestop/ Remove the BD PROCHOT box from the main window if enabled. Ensure SpeedStep is selected. Share some ThrottleStop screenshots. Include the main window, FIVR, TPL, and Limit Reasons panels. Many Dell Alienware machines experience throttling issues—provide more details and we’ll resolve it together.
Please verify the Set Multiplier option and adjust it to 45. Execute a basic benchmark such as the built-in TS Bench to assess your CPU performance. Configure it for a single-threaded run. Capture a screenshot of ThrottleStop during the load process.
You aim for the processor to operate at peak speed continuously. Activate the Ultimate Performance power plan. This can be achieved by executing the specified command in CMD with admin privileges and then setting the plan via Power Options.
Did you attempt to use the Restore plan defaults button in Power Options? It seems the BIOS or Windows has set the CPU multiplier to the lowest value, 12, which is slowing performance. The Set Multiplier setting in ThrottleStop can override this. Have you installed a recent Windows or BIOS update? @Analog recommended creating a Windows Ultimate Performance option. Ideally, you wouldn’t need ThrottleStop, but it provides an alternative if the issue persists. Press the C6 button on the main ThrottleStop screen to access the C states window. If C states are disabled in BIOS, the CPU will be limited to a 41 multiplier for single-threaded tasks. When enabled, the 9800X can run at 4500 MHz instead of 4100 MHz under light load. What should you do with your CPU? Restore it to default settings or overclock it via the FIVR window. You can fine-tune turbo ratios so the CPU consistently uses the 45 multiplier regardless of active cores. It looks like the default Dell turbo settings differ from Intel’s for a 9900X.
