Nvidia GT 750M Throttle at 80 Celsius

EDİT:

Hey my friends i have recently recognize that GT 750m throttle no related to temperature. My gpu throttle at 67 celsius or any temperature near, like the SS i have posted. What possibly can do this please help me, i have tried MSI afterburner to change voltage but voltage editing not enabled, i have overcloked and downclocked gpu but it still throttle not depending which temperature is, just depends playing any game. It throttle at the start and end of the any 3d game. Please you can find a solution.

Hello Friends,

I have a big issue that my GT750M is throttling. Here is my graphic in a average load game, help me fixing my issue please.

My laptop is Asus N550jv 127h İntel 4700HQ, 16 gb ram, GT750 m DDR3 4 GB Video card. It's a new laptop and coolers are very clean.

I have fixed Cpu Throttling wit stop throttle but cant fix gpu throttling with various programs. Gpu core clock throttles to 200-450 mhz whatever i do what program including MSI afterburner i use. This makes almost any game unplayable. I know my GPU is not a good one but throttling at 80 always makes it like a İntel HD graphics card. I think 80 celsius should not be the degree to throttle for such a laptop, is there any "Stop Gpu Throttle" program or BIOS edit program?

Only thing you can do is prop the laptop up using books to reduce the temps, get a laptop cooler to do the same or repaste the GPU(IMO best option)... It's difficult to repaste/repad the GPU but then your problem will be 100% solved...

 

I have noticed right now that my GT 750M throttle also at 70 celsius also. This is not a temperature problem this is a BIOS software issue.

How can i edit bios or whatever related program and set my Gpu throttle temperature to a proper degree please? MSI afterburner and similar software does not work.

Thanks.

 

You need an unlocked vBIOS and there is no such option for the GT750M..

 

Download Nvidia Inspector, go to the overclocking window, and check if Temperature Target is checked and set to 70C.

 

Is there any way to unlock vBIOS?

Nvidia inspector does not work, although i set priority temperature to 97, it still throttle after 70 or 80 celsius.

That machine is an oven. GPU downclocking is occur because the CPU hits TDP limit and then the whole system take a step back in clocks to prevent overheating. It's a "usual" thing for the N-series.

 

It's also the vBIOS/BIOS causing the throttling.. nothing wrong with 67-70C GPU temps IMO and I don't have such throttling on my 7970M at those temps.. It's just Asus etc causing this...

 

It's not the GPU it's the CPU that triggers the throttling. The original BIOS on that system is trying to prevent the components go above 80°C. The cpu hits 80 first, the the whole system throttle.

 

Is there any way to increase TDP limit? Why should there be a TDP limit when laptop sees maximum 67 celsius when FAN RUNNİNG %100?

Changing BIOS version to back versions may solve my issue?

I dont think Cpu triggers because throttling happens when cpu and gpu both 67 celcius.


Thanks all for your help, i try to solve this with your support.

 

I doubt it will be very solvable... The main things you can do is following...

1. Repaste CPU+GPU with some proper thermal paste like Gelid GC Extreme/IC Diamond
2. Use a notebook cooler to help drop temps a bit
3. The broke person solution IMO: Prop the back up with 2 bottlecaps or put your laptop on top of 1-2 books to help reduce the heat buildup...

 

Cooler won't be that efective. There are the fans and the red one sucks air through the keyboard not from the mottom.

 

Use latest ThrottleStop and uncheck BD PROCHOT.

 

You mentioned that you were using some sort of stop throttle program. Did you mean ThrottleStop? Head over to the ThrottleStop thread and post a screenshot of how you have ThrottleStop setup if you need some help with that program. You should also run ThrottleStop with the Log File option checked while gaming so you have an accurate record of what is going on. Head into the Options window and turn on Nvidia GPU monitoring before you start logging data.

Many Asus laptops have throttling problems. I think your laptop performance can be improved when ThrottleStop is setup correctly.

 

I have N56vz i5 & gt650m.. i don't think i've seen throttling which eventually decreases gaming performance with cpu & gpu temp is 80-90 deg C

 

Sorry but i say that i have edited my post after recognization that my laptop throttle not dependent to temperature. It throttle although cpu + gpu both 67 celsius. And my laptop is new and there is no cooling problem. After i have installed notebook fan control and running %100 fan the temperature of Gpu + Cpu never goes above 70 celsius. But gpu throttles. I think it is a Load or power dependent stupid throttle. Thank you.

Yes i have fixed Cpu throttling with perfect program Throttle Stop. Before i use throttle stop my cpu was going down to 700 mhz from 2400 when playing 3D games although the temperature was not high. What a stupid engineering from Asus. After throttle stop software cpu does not throttle with un picking BD prothocol. But gpu still throttle non-dependent to temperature but dependent to gpu load.

Thanks all for all helps, i am still wasting my all free time to solve this stupid engineering issue.

 

The GPU thorttling is due to temps... You have to reduce them by repasting/repading or raising the bottom of your laptop/using a notebook cooler...

 

GT 750M throttles at 60-70 celsius, is that a high temperature for a gpu? If not, it does NOT throttle due to temperature.

 

Well it's not really high.. IMO 70C+ is high...

 

What is the PSU power rating?

HWiNFO will show the CPU power consumption but I don't know if it shows the estimated GPU power.

The 4700HQ has a 47W power rating. Notebookcheck estimates that the GT 750M needs 35W to 40W so the system is likely to throttle performance if running off a 90W PSU. However, using a higher rated PSU may not overcome the limit unless the computer is clever enough to detect a higher power source.

Dear John,

My psu is 120 watt. Thank you for your interest.

I am currently tring undervolting cpu

 

Dear friends,

About my Asus N550jv gpu throttling issue:

I have solved gpu throttling:

Just downgrade the BIOS to older versions. I have done it to 206 and Gpu doesnt throttle, performance is nearly what it should be. But Cpu still throttle although temperature is not above 60 celsius. Throttle stop software still needed for cpu throttling, but this solves gpu throttling. So;

1- This is not a hardware issue, just a BIOS software issue.
2- This issue is with BIOS version 208.
3- This is a poor engineering from Asus engineers that laptop cant give the performance which it should. Meanningless throttling kills performance %50 and more.
4- I have spent more then 1 month of my free time to solve this poor software engineering.
5- I have not tried older then 206 BIOS versions but with older versions maybe also meaningless Cpu throttling does not exist.
6- I have to still use throttle stop software to stop Cpu throttling (if i try older BIOS versions maybe i dont need)
7- Shame on Asus engineers.
8- Shame On asus Enginers.
9- Shame On Asus Engineers.
10- SHAME ON ASUS ENGİNEERS.

 

Here a way with throttlestop 8.0 that did the trick for me, now CPU+GPU 100% load, no throttling at all GPU +Turbo and CPU +Turbo

This solution helped me to get 100% out of my DELL 7447 (Pandora) i7-4710HQ, GTX850m(4GBDDR3), 16GB DDR3L, FullHD IPS

I hope and I am confident, this trick will help you. Your 120Watt PSU should be powerful enough

SOLVED TDP and Power Limiting (Haswell) SOLVED the easy way

big Thanks to throttlestop 8.0 and a more powerful 150 Watt Dell AC Adapter (60Watt more than original, just to be safe for experiments)
1. deactivate C1E
2. activate clock Modulation 100%
3. in TPL (Turbo Power Limits)
> higher package power Limits (my i7-4710HQ Package Power Long 54Watt, Package Power Short 68Watt)
> higher PP0 Current Limit (if possible), higher PP0 Power Limit lock and clamp it (just set the Maximum rated AC (PSU) power of you AC)
> tick Intel Power Balance and set Intel CPU and Intel GPU to 31
4. undervolting CPU Core & CPU Cache Offset Voltage by xy (my i7-4710HQ rockstable -70mV)

Best regards,

Marcus Conrad
