Overclocking Nvidia GT750m?

How can I OC my GT750m? I know there's a lot of app that can OC a graphic card, but Im still unclear on the process of OCing

 

1- Download GPU-Z for Monitoring, Check if your temps (max temps while gaming) allow some OC headroom. (e.g., Battlefield 4 MP 64 Players).
2- DL Nvidia Inspector for OC.
3- push to +75MHz core/250MHz Memory and test (semi-random safe OC values).
4- Play a demanding game on CPU+GPU and check your max temps with GPU-Z.

 

So I tried GPU-z with BF4 and the temp were quite good I guess, around 60*C to 67*C

SUPER EDIT: BF4 crashes everytime after I tried OCing to +75MHz/250MHz.. sigh Is there any other option other than 75/250 or is this the end of my OC journey? haha

 

overclock now just core and set any number between 0 and 75.
notebook model would help.

 

What do you mean? I just change the core and see if its ok without changing the memory?

Here is my laptop, Lenovo Y410P tho mine is with a GT 750M Nvidia GPU not a GT 755M

EDIT: So I did only change the core to +75 and the game did not crashed, the temp were the same as before, around 60*c to 67*c. What's next?

 

you RAM doesnt like to be OC'd, so max out the core (+135MHz) and enjoy

 

Thank you, I did it and I can run a perfect stable 60 FPS on BF4! HEHE but boom, it did crashed after like 30 mins of playing but its fine, better than crashing every 2 mins haha x'D

 

What driver version do you use ?

 

Latest one, 344.75 and I have one small problem now but it does not apply to all, maybe I need to reboot my PC or Idk, but I tried playing other game (BFBC2 and Dragon Age:Inq) and I noticed something after I OC, there's like this small stuttering, it's not going smooth.. but on BF4, it does went well, I dont know why haha but anyways, time to sleep, I'll catch up with you tomorrow, cheers for the help!

 

limit those to 60 fps and enable vsync by D3D Overrider.
Lower clocks until rock solid crash-free and the 5MHz less just in case

 

Thanks, I tried with the D3D overrider and the game crash. I guess the Vsync is what causing it to crash. I will report back if I found any problem, thank you And yeah, after gaming, do I have to change back my OC to normal? To keep the GPU at a normal working state

 

The gpu goes to idle mode by itself

 

Nice! Alright Thank you guys hehe

 

vsync should never be turned on, it introduces input lag caused by 1 frame always presented late

 

You forgot to tell that this you personal opinion.
And yeah, it truly gives 1 frame lag which equals holy... 16ms ping!.. wait... just 16 ms? yeah, just 16ms. Which means that only those who notice that lag should turn it off, but not "vsync should never be turned on by anybody".

@germs95, Sorry about BF4 crash, that method was for your other games which had strange stuttering after more fps. BF4 is 64bit and incompatible with that program, you need to exclude it in that program by creating profile and checking detection level NONE. And fps limit is done for each game separately after that in nvidia inspector (try to google for more).

 

BF4 has built-in triple buffering enabled by default. Console/user.cfg command is RenderDevice.TripleBufferingEnable [0,1]. FPS limit command is GameTime.MaxVariableFps [FPS].

Guys... I have a question, when using MSI, I set the core to +120MHz then I restart my computer, when I check back, it goes to +405MHz and when I try to change it, it won't work. Ummm any clue For now, Im using EVGA since MSI is giving me that weird problem :/

 

2- DL Nvidia Inspector for OC.

 

Well I did use Nvidia Inspector but then it annoys me that I have to open it everytime I reboot and set the core everytime because it will go back to 0

 

In Inspector OC window, right-click on Create Clocks Shortcut and select 'create clock startup task'. This will add a task in Windows Task Scheduler to automatically apply your OC at startup 30 seconds after you log on. The clocks will still reset whenever your system wakes from sleep or hibernate, so you need to add a manual trigger to the task on System Power-Troubleshooter Event ID 1 to have it automatically apply the settings on resume from suspend mode.

 

Thank you And do you know any OSD app to monitor Temp? Preferabbly a standalone OSD monitoring app that does not have any OC cause Im afraid that if it has, it will overwrite Nvidia Inspector

EDIT: If I close Nvidia Inspector, will the OC go back to default or will it stay?

 

Standalone RTSS + HWiNFO64 for OSD.

OC will still stick after you close Inspector.

 

Cheers, sorry for asking too much, Im so new to OC haha :hi2:

 

No problem.

 

Well this thread was just what I was looking for. Thanks everyone.
So, is temp. the only thing I need to worry about with this gt750m? After reading the posts here, I overclocked it the 135 MHz and my GPU temp is still only 58-60. If I want to overclock it more, do I just select "performance level 1" unlock the min. and move the slider to (lets say) 150MHz and watch the temp doesn't rise to a dangerous level?
I haven't done anything with the memory offset slider or any of the others, should I ?
I'm using Nvidia Inspector and have driver version 347.25 btw.
Thanks again.

 

Yes, temperature is the main killer of overclocking. 135 MHz is fine, as long as the temp is not over 80/85* IMO but I do not OC anymore tho, I don't see any much difference so might as well be safe and stick with the normal one hehe.

 

You can't OC more then 135 core anyways due to NVIDIA limit.. You need an unlocked vBIOS which isn't there for GT750M..

 

I used afterburner to oc +135/300mhz and its stable.

I tried to do 340 memory and play a game but it underclocks to 405 core/ 800 memory. It wont change at all until i restart.

Does this mean it cant handle more than 300 mhz memory?

Single 750m on y500

 

@TomJGX
Thanks for taking the time to respond, I appreciate it! I'm using nvidia inspector, and seem to have the option to unlock it there. I did that and played with the slider, then chickened out. Unless I'm misunderstanding the program and the overclock wouldn't save. which is possible.
@germs95
Thanks, your right, better safe than sorry I guess. I do wonder if OC ing the memory would have much benefit, or should I just leave it alone?

 

Hey guys, I am a complete noob about this, I have a Acer V5 and i am not liking the results i have seen of overclocked laptops. I am not sure about those big numbers Im scared it will explode because i dont have any cooling pad. What do you think? Should I do the same?
?

 

Its really recommended not to do it if you dont know what you're doing. A cooling pad would help a bit but if you do OC a 750m, make sure you stress test it to see if its stable and it doesnt get too hot, If it gets a temperature over 80C, back off the OC or otherwise sooner or later you might end up frying it. I only OCed the memory of my 750m to squeeze out some extra bandwidth since i have the DDR3 version and not the GDDR5 version

 

Hi James D, Im newbie here i have no idea how to write you directly. I need some quick info about overclocking GPU, coz my game constantly crashes. Have nothing else to try than this, and i cant do it. My FB https://www.facebook.com/lFueL , please hit me up.
THANKS, Dave

 

Hello there, i would like to know more specific detail about OCing the Nvidia 750M, i am just not sure if im doing it right.
In "Overclocking" tab at Nvidia inspector i have 3 options "Performance level (0-2) (P8, P5, and P0).
I have 2 GC with SLI function. So 2 of them are these 2 GCs and one is internal GC of the laptop? If yes, shouldnt 2 SLI cards have the same values?
