Uncertain about the behavior at 800Mhz.
Hi everyone, I'm trying to solve a persistent issue with my Asus Tuf fx505. It runs an i5-9300h and GTX 1650, but I've been experiencing serious power throttling. Even when idle or browsing the web, my CPU stays stuck around 800Mhz instead of the usual 3500-4000Mhz under load. XTU and Afterburner confirm this consistently. My performance is really poor, and the stress test showed power limits instead of thermal throttling. I've rebooted multiple times, changed power profiles, and tried plugging it in and out, but nothing seems to help. Recently, I noticed that when I put it under load, the processor cache frequency drops dramatically from about 2.1Ghz to 0.8Ghz almost instantly, and the core frequency follows a few seconds later. It's strange because it can run at normal speeds when idle, but everything plummets under stress. I think something like the armoury crate might have set my turbo limits to 5W. After adjusting manually, things are back to normal. Thanks to Unclewebb and Threecakes for their help and guidance!
It might be a power-saving option, but it shouldn't slow down during high demand. Have you attempted to reset the BIOS?
I believe you're using the FX505GT and the same problem has been occurring for about three days. I've reset the BIOS to defaults, drained the CMOS battery, restarted it, flashed the latest BIOS, and performed a hard reset, but nothing has resolved it. I reached out to Asus support two days ago and asked them to send me images, videos, and feedback so their team can help. They haven't replied yet.
THANKS TO UNCLEWEBB FOR THE HELP Here's a solution to fix the Power Limit Throttling issue: Download ThrottleStop and look at the settings below. Image 1-Turbo Boost Limits (TPL) Window 1. Check both Turbo Boost Long Power Max and Short Power Max boxes. 2. Change Long Power Max to 45 and Short Power Max to 60. 3. Check the Lock box then Apply the new settings and click OK. (OPTIONAL) Look for Speed Shift and change Max to a different number if you do not like the temperatures you see. Image 2-FIVR Window 1. Check Disable and Lock Turbo Power Limits box then Apply the new settings and click OK. Image 3-ThrottleStop Main Window 1. Uncheck Disable Turbo box and Save \ Image 4-Options Window 1. Check Start Minimized and Minimized on close (OPTIONAL) Asus set the PROCHOT Offset value to 8 so the CPU will throttle when it hits 92C. Change this value if you want the CPU to throttle at a different temperature.
It appears the laptops are experiencing incorrect power restrictions due to BIOS or Asus software. The turbo limits are stuck at 5 Watts for both short and long durations, causing significant throttling. Adjusting the limits to 45W for long sessions and 60W for short ones, then applying ThrottleStop Lock, prevents them from reverting to 5W. To modify or remove these settings, exit ThrottleStop, delete the configuration file, and restart the computer for a reset. When you activate ThrottleStop again, a new file is created restoring default values. This issue seems linked to Armoury Crate, though a Dell representative previously mentioned similar power management problems.
Hi everyone. Thanks for your support. My brother's laptop began experiencing this issue lately. After applying throttlestop, I adjusted the power limits to 45W and 60W as advised. Given that the chipset's TDP is 45W, is it safe to set those values? I thought since the CPU won't run at full capacity during games, it shouldn't draw maximum power. Still curious to be sure. It might also be due to a recent driver update, so if anyone finds a patch or fix, please share it here. Appreciate your help!
Intel suggests aligning the long-term turbo power cap with the TDP. For a chip with a 45W TDP, matching it to 45W is suitable. When considering the short-term turbo setting, Intel advises increasing it by 25% above the rated TDP. Adding 45W plus 25% equals 56.25W. Exceeding the rated TDP temporarily is common for Intel CPUs in both mobile and desktop forms. If 60W seems excessive, opt for 56W instead. To keep your laptop cooler, lower these numbers below the rated capacity—this will reduce full performance but avoid throttling. An example of this occurred when an Asus engineer set both limits to 5W, which was an overreach. On 6-core mobile processors, exceeding the 45W rating is typical, with 70W and 90W being standard. As long as the heatsink manages additional heat, slightly higher limits are acceptable. This could stem from a recent update in Asus Armoury Crate software.
