Extreme, random slowdown when playing any game. Lenovo Y510p

[weirdiolio]

Hey guys!

I have been getting random slowdown in any 3d game on my y510p. This has only been happening since I used throttlestop, and/or updating to win 8.1 (Two weeks ago). I've been monitoring my cpu temps, and when the slowdown occurs, the temps are around 87 C, however, this isn't any different from my normal temps while playing games. Even ingame, (Using Planetside 2 as a example), I could be just sitting there, with no difference in gameplay, and a slowdown would occur, for about 10 seconds, then in the next 30 seconds. Finally, I know the cpu is the problem due to CPU Z showing my mhz going down from 2400 to 800.

Any way this could be helped?


Edit: This is the single Nvidia 750m gpu model.

Don't use throttlestop then 😵

Actually... This started happening after I used throttlestop for the first time, I don't use it now 😛

Your CPU is slowing itself down automatically most likely because of overheating. Those temperatures are pretty high even for a laptop. Get a notebook cooler, try cleaning your CPU cooler and possibly even changing your thermal compound (only if your laptop is 2-3+ yrs old). Don't put it on wooden surfaces because they tend to heat up and transfer that heat back to the laptop even more.

Thanks for the quick reply! I've looked into notebook coolers/heating pads for this model, but I've heard that they don't work all that well with this laptop...
Also, I currently have my lenovo on a plastic/ rubber coated plate(Think a solid stand with no legs), with my wood desk underneath Would that be fine?

Yeah, coolers aren't that great but the important thing is to raise the bottom of your laptop and basically have good airflow underneath it. Now all of this is assuming that it is an overheating problem...

Exactly... The temps of my laptop remain usually in the high 80s, and rarely flucuate, even when not slowed down... So.. I'm thinking this isn't about overheating.

I'm out of ideas, pretty sure win 8.1 isn't the problem, consult someone smarter than me...

Uh.. Alright.. Btw.. How can I unsolve this thread?

The Lenovo Y510P has several throttling problems that can be triggered by heat or by power consumption. Here's how fast a Y510P can run.

The first question is why on a good day does your Y510P only run at 2400 MHz? Answer: Lenovo quietly added a feature to this laptop that disables Intel Turbo Boost soon after you start gaming. They forgot to mention that and most review sites also glossed over that problem. 2400 MHz is the default speed for a 4700MQ but Intel Turbo Boost is supposed to be enabled and this CPU should be running far faster than 2400 MHz when gaming.

Another common problem is BD PROCHOT which stands for bi-directional processor hot. This is a signal path to your CPU and lets other sensors on your motherboard send a signal to your CPU which tricks it into thinking that it is too hot. This forces it to immediately throttle down to 798 MHz and it can stay there for quite a while or indefinitely if a sensor is broken. Does that sound familiar?

If you spent time learning about ThrottleStop and did some Google research, you could have diagnosed this problem as well as solved it. No other software in the world lets you disable the BD PROCHOT signal path or lets you enable Turbo Boost like it should be enabled. If you would like to try this program again, you can download the latest version from here.

How do I know so much about this laptop and its problems? Besides owning a Y510P, I am also the guy that wrote ThrottleStop. I specifically added features to this software to deal with the Y510P and its issues that Lenovo decided to ignore.

Thoroughly cleaning out your laptop is a good place to start. The cooling solution provided by Lenovo is in the barely adequate category. If everything is not perfect, you start running into problems. Don't get me wrong. It's a decent laptop once you fix its numerous issues.

Thanks for the great response! I'm taking my laptop in to get cleaned out and possibly some new thermal paste applied, since it's just over a year old. Thanks for the help!

Hi, weirdiolio did you manage to fix overheating after cleaning the laptop or not ?
