CPU (i7-4910mq) Keeps Throttling Down to 800MHz Unnecessarily

[-ism]

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!

if it has a decent biois, go there and thermalthrottling option should be there, otherwise improving cooling could help, changing thermalpaste and running the fan at higher rpm

how quickly do you get up to 70°C where it throttles? IF it reaches it fairly quickly, the thermal paste might not be as good anymore. But your CPU throttling at 70°C is odd definetely

Control your power and thermal settings from the bios first, disable any thinkvantage stuff that’s installed, re-paste the cpu, and make sure the fan/Heatsink is clean.

 

As a thinkpad nerd, it’s a T440p, it just sucks, don’t expect greatness out of the haswell machines.

But I would try bios power management first.

Your problem is a common one.

 

Use ThrottleStop to disable BD PROCHOT. Set the FIVR Non Turbo Ratio to 1.

 

Post screenshots if you need help.

My T440p with an i7-4800MQ did the same. I used ThrottleStop to disable BD PROCHOT and haven't had that problem ever since

That did it, getting a rock-solid 60 FPS now. Thanks for the suggestion! Still some micro-stuttering but that could come down to the game or some other emulator setting.
