Unusual CPU throttling occurs.
Unusual CPU throttling occurs.
Hello, I'm working on identifying CPU throttling issues I haven't fully resolved. I'm using an i7-13700 (non-K) on an ASRock Z690 Extreme with the latest BIOS. Benchmarks are showing lower results than expected, and the CPU only reaches around 180W during stress tests, occasionally spiking to 200W even though the TDP is higher. I've set PL1 and PL2 to maximum, but it seems like a current limit based on HWinfo64 is causing the problem. I'm attaching a screenshot for reference. The graph starts while using Chrome, and you can see the throttling begins right after launching Cinebench. It's curious that some load still triggers this issue. This is my first build, so any advice would be greatly appreciated.
Your load temperatures are looking down. How much have they decreased?
It seems like you're asking for advice on cooling systems. Would you like suggestions for remounting a cooler or checking thermal paste? Also, what type of case are you using?
The non-K CPUs are blocking FIVR voltage controls, preventing adjustment of the IccMax limit. Setting IccMax to a low default can cause steady EDP throttling during full load tests such as Cinebench. Choosing a K series CPU for overclocking is better even if you don’t plan to. Consider using ThrottleStop 9.6 at https://www.techpowerup.com/download/tec...rottlestop and close the ThrottleStop window. Look for red indicators under the CORE column when Cinebench runs. Share a screenshot of ThrottleStop with the Limit Reasons open while Cinebench is active. Also post images of the FIVR and TPL interfaces so I can review your configuration. It’s warm, but the temperature is typical for an air-cooled Intel CPU during Cinebench. The CPU isn’t experiencing thermal throttling.
You received this CPU at no cost, which explained why you chose to integrate it into your system. I've included images from ThrottleStop showing the initial performance data. The first snapshot displays EDP OTHER yellow under both ring and core during idle, turning red under core when using cinebench. Additional screenshots capture the situation while cinebench is active.
The latest screenshot displays a consistent 51.00 multiplier, which is optimal for a 13700. Before beginning a game or Cinebench, verify the Log File option. This helps confirm the 51 multiplier remains stable. All indicators appear normal so far. Temperatures remain within expected ranges.
