[Help] Overclocking nVIDIA 745M

[HerySean]

Hello and Yes it's a laptop, I'm trying to overclocking my graphic card but there's 1 problem: I have no experience of doing so, and II don't know what software i'm gonna using, and even if I know what software I'm gonna use I have no idea which setting i'm gonna adjust, can anyone help me? 

 

Thank you.

I'll post my graphic and RAM down below.

 

Note: The actual VGA is 2GB

Use MSI afterburner. Increase Core clock, when you've reached its limit then start increasing memory clock.
P.S. It's not a good idea to OC  a laptop.

It really is not a good idea to overclock a laptop, as the cards are usually very weak compared to desktop grade variants. Overclocking a laptop will not get you much of a performance increase, and will just make your laptop much hotter (making it run worse) and shorten your laptop lifecycle. 

 

That being said, I recommend MSI afterburner with a benchmark tool like valley benchmark and slowly increase the core and memory clocks until you find the sweet spot for performance.

I have no idea hat you just said, what is a "sweet spot for performance"?

Sweet spot is the point where your overclock isn't too high that it will crash your computer/overheat it, nor the point where it is overclocked so minimally that it doesn't even matter. It's the spot in the middle that will grant you the best performance while keeping your PC healthy.

Just keep increasing core clock by lets say "10". then test if it it's stable and temps are fine. If all good increase by 10 more and repeat.
One temps are too high or system unstable, go back to last stable clock. then try same thing with memory clock.

Well yeah, that's how you OC, keep increasing Core clock and memory clock little by little(+245 to memory from get go is too much ). Test it with program called Heaven benchmark

Yeah, I took your advice and reduce memory clock down and increased core memory to 50%, I think it's kinda too much, maybe I should go with 25%, what do you think on my current clock?

I think that you should benchmark it and see if you system is stable.
