Hi iv been scratching my head for the past few months, i got this laptop asus k75vj, and it has a dedicated gpu the gt 635m, my problem is when i play games sometimes it will throttle down its clocks when it gets to 85c, i was wondering if there is a way to disable this, i know its a laptop, but i really don't care i doubt it would go past 90c, i just want to stop the damn throttling, when ever this happens my games slow to a crawl for a few seconds, as expected do to the damn annoying throttling.

The reason i ask this is because there are other ppl on the internet, with my gpu and they get to 90c no problem, and never get throttle'd.

what surface are you gaming on?

have you considered a cooling pad?

have you repasted it?

 

[soulwrath]

throttlestop program stops any throttling but you risk the chance of frying your mothoerboard if you dont have sufficient cooling

i have my laptop on a wood table,
.

are cooing pads necessary even if it on a desk?

no repaste yet, whanted to try something else before doing that, sooner or later ima gona have too.

issint that for intel cpu's? whats throttling is my gpu not my cpu.

I can't see increasing the throttle temp for a mobile GPU as ending well. It's set there for a reason.

The OEM who designed the laptop really sucks at what they do if they can't even cool a 635....

Intel CPUs have a feature called BD PROCHOT or bi-directional processor hot. This is a signal path to the CPU so other items on a motherboard or the GPU can send a signal to the CPU. This signal tricks the CPU into thinking it is too hot so it immediately begins to thermal throttle which usually drops the CPU down to about 800 MHz. FPS will drop like a rock when this happens and the GPU might slow down too because the CPU is unable to keep up. This was a significant problem for many Asus laptops.

ThrottleStop can be used to disable the BD PROCHOT signal path so these signals to slow down will not go to the CPU anymore. If your CPU ever gets too hot, it will still be able to thermal throttle if it ever reaches the Intel specified thermal throttling temperature. No software, no matter how you have it set up, can disable this safety feature.

Long term, it is hard to say if your GPU will be happy or not. If it only lasts 5 years instead of 10 years you probably won't be too concerned but if you cook it by the end of the week, that won't be too good.

I would suggest turning off the BD PROCHOT function and then closely monitor your GPU temps. ThrottleStop has a feature so you can set up 2 different profiles and automatically switch your CPU speed based on either the CPU or GPU temperature. In the second profile, you could disable Turbo Boost so your CPU runs slower and puts out less heat without it having to drop like a rock down to 800 MHz. By default, the Lenovo Y510P has this feature. It disables Turbo Boost when gaming to keep the thermals under control.

Not sure what Asus was thinking when they produced gaming laptops that had a hard time playing games smoothly.

Before doing anything, it would be a good idea to make sure your heatsink fins are clean. A good cleaning with some compressed air can really help drop your temps.

thanks i will check this out, i had no idea the intel had such a technology, but im almost sure the cpu is never throttle'd i run my games with msi afterburner, on screen monitoring, , the only thing that lowers its clock is the gpu, the cpu stays at the max turbo boost speed witch is 3.0 or 3.1 not sure right now.

Yesterday i decided to take a look at my vents and fan,but they were both almost immaculate with no dust, not very surprising this laptop is about 5 month's old.anyways what's left is to try and re paste y gpu see if that makes a difference.
