i5-7600K runs at 0.80Ghz initially, then slows down at Base Clock
Hey! Today I powered on my PC and noticed it was running really slow. I checked the Task Manager and saw the CPU stuck at 0.80Ghz. I looked up solutions online and found a helpful guide at bradshacks.com. It helped fix the problem and now I need to enable ThrottleStop to reach above 800Mhz. Before that, I tried several BIOS tweaks on my ASUS Strix Z270F: turned off Intel Adaptive Thermal Monitor, disabled C States, reset to normal EZ Mode, and updated the BIOS (which showed the CPU could hit 4.5Ghz). Now it’s capping at 3.9Ghz. On ThrottleStop, the limits were showing PL2 (yellow) for Core and Ring. Before applying the fix from bradshacks.com, I saw PL1 in red and PL2 in yellow under Core. I’m planning to replace the CPU and motherboard soon (targeting Intel 11th gen), but I’d love to know if it’s possible to get back to 4.5Ghz later. This would really help with gaming, especially with Bottleneck already in place.
Several programs on your machine may be malfunctioning. They are restricting power output to zero watts. When the Clamp feature is active in the power limit register, the CPU will be forced to operate at 800 MHz. Share screenshots of your ThrottleStop configuration. Show the main window, FIVR and TPL windows, and any red boxes in the Limit Reasons section. Opening the TPL window and securing the turbo power limits register has assisted some users in reaching full performance. This action locks these settings so no software can alter them. If you notice a red BD PROCHOT entry in Limit Reasons, remove the corresponding box on the ThrottleStop main page. Different systems use various throttling techniques—provide screenshots if you require further guidance.
Attempted to secure turbo speed but no adjustments made. Attached are screenshots of FIVR and TPL: https://imgur.com/a/CzCV9VS. Also shared a picture showing what occurs in Throttlestop at startup with 3.8Ghz: https://imgur.com/a/IQUx9ir. When I didn't open Throttlestop immediately after booting on Windows, waited about a minute, and then opened it, my CPU was at 0.8Ghz. After roughly one minute, PL1 turned yellow and the clock returned to 3.8Ghz: https://imgur.com/a/Uc93MGk This is quite unusual, lmao.
@LaBaguetteBelge You asked why your turbo power caps were set to 100? To prevent throttling, adjust both turbo limits to their highest setting, 4095, and configure the turbo time limit to 28 seconds. Ignore any clamp settings and verify the Turbo Boost Short Power Max option. I’m aware Brad prefers clearing this setting, but as long as the caps are correct, it’s acceptable. Now review the Lock option and confirm OK. In the FIVR section, disable and lock the Turbo Power Limits box. Intel CPUs support several turbo limits; this setting handles the secondary ones. Since you’ve locked the CPU register, exit ThrottleStop, remove the ThrottleStop.INI file, and power off your machine to reset the register properly. This is the recommended method. In the FIVR window, all ratios are set to 39, which caps performance at 3900 MHz. Adjust these values to match your desired speed. Also, align the TPL - Speed Shift Max with the highest turbo ratio you’re using—typically setting it to 255 avoids conflicts. What are your current turbo ratios and power limits in the BIOS? This might be the root cause. If you modify the BIOS, delete the ThrottleStop.INI file before running ThrottleStop to ensure you start from a clean slate. Don’t rely on the Task Manager for this; it’s less precise. ThrottleStop indicates the CPU multiplier is at 39.00, which aligns with the correct setting when all ratios are 39.
Ok thank you very much, I did everything you said and now I'm able to reach 4.59Ghz. For the bios settings, I don't know much, everything looks set on "Auto" Here is a screenshot of everything who could be interessting : https://imgur.com/a/s0PyQZy I must have Throttlestop to run when I boot my pc to have the cpu clocked at 4.59Ghz, If not, my cpu stay stuck at 0.80Ghz.
The latest BIOS screenshot displays CPU - Power Management Control settings. It appears the turbo power limits are configured there. There are two power restrictions in place. I’m uncertain if the BIOS is mistakenly setting both to 0 Watts, or if some software on your system is doing the same. This causes the CPU to freeze at 800 MHz. On certain MSI systems, MSI Dragon Center seems to be linked to this issue. You have an Asus motherboard, but are you using any comparable Asus software that might be triggering this? Any game optimization tools? ThrottleStop can resolve it, though most users prefer identifying the root cause first.
The power management settings are configured as shown. I attempted to disable certain states but didn’t fix the problem, so I left them off. I’m aware I lack these features. The only adjustment I made was changing a setting in Equalizer (APO Equalizer) to "Install as SFX/EFX" on my sound source. After rebooting, I noticed the 800Mhz frequency—whether this was the cause isn’t clear. I removed the software and Asus AI Suite after trying them without success, but I’m unsure what could be responsible.
@LaBaguetteBelge Your second BIOS screenshot indicates the positions of the two turbo power limits. Visit AI Tweaker - Internal Power Management. These are currently set to AUTO, meaning the BIOS should handle the turbo limits properly. You can manually adjust them. Set both limits to 4095, similar to what you use in ThrottleStop. After booting, avoid running ThrottleStop and observe if your CPU throttles. It’s challenging to pinpoint exactly when this issue began or what caused it. I’ve heard about this problem on Asus boards, but I haven’t found a reliable source yet.
I think I've identified the problem, though it seems really simple after all my attempts. I recalled this morning that I had a software for my graphics card—MSI Dragon Center. I remembered enabling a CPU setting, so I turned it off in the software, ran an update, then re-enabled the CPU setting and restarted my PC. Now it works fine without needing ThrottleStop. That was the original issue. I was considering buying an MSI motherboard for future upgrades but am now unsure. Thanks a lot for your help!
