Hello friends, I would like to use my laptop, a ThinkPad T440p, with an Intel Core i7-4910mq processor for some Wii emulation on the go, but as the title of this post would suggest I'm running into quite the snafu. I've been keeping CoreTemp open while running Dolphin (Wii Emulator, Kirby's Return to Dreamland) and I've noticed that the CPU clock speed keeps dropping down to 800MHz. When this happens, the emulator drops from a steady 60 FPS to a glitchy 24. I figure that some sort of temperature protection is the cause of this, so here's what I've done so far. Enabled high-performance mode in Windows power settings Set minimum CPU Performance to "95%" in power profile (does nothing) Closed every other program It appears that as soon as I hit 70 degrees on any of the 4 cores it throttles back. Is there anything I can do to prevent this? I can see in coretemp that the tj max is 100 Celsius. Is there anything else I can do to get my PC to take advantage of the seemingly available headroom? Any advice would be appreciated, thanks for taking the time to read and reply!

Check for a solid bioimage; if present, visit the page and ensure the thermal throttling feature exists. If not, consider enhancing cooling by switching thermal paste or increasing fan speed.

How fast does it warm up to 70°C at throttling? If it hits it quickly, the thermal paste could be less effective. Your CPU throttling at 70°C is definitely unusual.

Your issue is typical. Apply ThrottleStop to turn off BD PROCHOT. Adjust the FIVR Non Turbo Ratio to 1. Share screenshots if you require assistance.

Another user with an i7-4800MQ on a T440p also experienced the same issue. They used ThrottleStop to turn off BD PROCHOT and haven't had that problem anymore.

That's great news! Achieving 60 FPS is solid. The micro-stuttering might be due to the game or emulator settings, but it's something to investigate further.
