i9 14900K performance problems with Facebook connection
I’ve observed unusual CPU activity when Facebook is active in the browser. After some time, the temperature increases and varies between 80°C and 90°C. This only happens with Facebook—not other sites. I reinstalled Chrome without extensions, but the problem returned. I also tried Edge, but the issue persisted. Since Chrome and Edge use Chromium, I switched to Firefox. I cleaned up my PC, installed just essential drivers and Firefox, and everything worked for a while. Eventually, even Firefox started showing the same problem. I checked QuickCPU and got detailed data: when the Facebook tab was open, P-cores ran near 5.7 GHz, power use was about 90W, and temperatures stayed between 70°C and 80°C. Once the tab closed, everything normalized. In another session, browsing other sites and YouTube, temperatures dropped to around 40°C (with occasional spikes up to 60°C during page load), and power consumption halved. My setup includes an ASUS ROG Strix cooler, latest BIOS, and default power limits. Temperatures are around 40°C during idle, and up to 60°C in games. The Intel diagnostic tool passed. Although hardware appears normal, I’m still puzzled about the cause—possibly a background script or tracking process from Facebook. It seems like some hidden activity is consuming resources. I don’t know how to stop it, but I’d appreciate advice on identifying and resolving this issue. Anyone else facing similar problems?
You've successfully saved the newest BIOS, which contains the microcode update as indicated in the image.
That's right, it's because Zuckerberg collects your personal data, uses it for credit, shares your photos with advertisers, and drains your finances. Don't worry about it.
Ensure your BIOS runs on the most recent update. The default CPU profile is typically Extreme; I recommend changing it to Performance and turning off IA CEP in Bios. For even better performance, consider using Intel XTU to reduce the P-core clock from 57x to 55x, which can improve temperatures and stability. The 14900K tends to run very hot and may require some adjustments for optimal control.
Could hardware acceleration be turned off in the browser or on Facebook? What’s simple for a GPU to process can demand much more power from a CPU with built-in features. My browser, Brave, which uses Chromium, has problems with the standard 3D engine, so I switched to OpenGL and it works better. I also own a 14900K, my second one after the first warranty. Both have overheated and become unstable out of the box. After updates and microcode fixes, the second model still struggles. If you haven’t reduced your 6Ghz P cores to 5.7Ghz, be ready to adjust that setting. That’s the only solution I’ve found for this chip. Look up “brave://flags/” in your search bar if you need more help.
I've already adjusted the power settings manually—set the power cap at 253W and the core current limit at 400A. With Intel XTU, I tried several configurations and then tweaked BIOS settings: reduced clock speed to 5.5GHz, synced all cores, activated Adaptive mode for SVID, and set a negative voltage offset of -0.065V. Temperatures have improved—now around 80°C when Facebook is open, compared to previous spikes at 100°C. That’s definitely an improvement. Still puzzling is why this only occurs with the Facebook page; other sites don’t trigger it, even those that are more demanding. GPU-based 3D rendering is enabled. As @jmwhite33 noted, I’m not surprised anymore when Chrome’s Developer Tools show long CPU-heavy tasks. This could be an issue for processors using both P-cores and E-cores. The challenge is figuring out how to block or limit those non-essential tasks.
