Sager NP8130 GPU OC

If I OC the 560M in an NP8130, will the stock 120W power adapter suffice?

 

Yes. Nice thread btw.

 

Even to the fullest OC?

 

Most overclocking programs like MSI Afterburner and nTune don't affect the voltages, mainly just the clock speeds, so it'll stay around the same voltage. You should be OK but we always caution people who plan to overclock of course

 

But of course most overclockers want to increase the voltage as well to maximize the OC, right? In that case, 120W can't just cope with it?

 

Potentially, but on laptops it's often the cooling that reaches the limit first. There just is not much headroom for overclocking in a laptop with a powerful card because of the heat generated. You'll be seeing 90+C with even a modest overvolting.

Also, as overvolting has a higher chance of frying the card outright, it's highly discouraged unless you don't mind the risk.

 

To expand on this a bit, with most of these GPU's when overvolting you're not even hitting the max voltage the GPU can handle, these GPU's and the one in question, 560M, are undervolted underclocked GPU's from desktop cards (albeit underclocked and undervolted to meet the lower TDP of laptops).

The 460M and 560M use roughly the same GPU chip as the GTS 450 desktop card (460M using exactly the same GPU, 560M slightly tweaked for voltage table) which sports higher voltage and clocks, another thing to note is that these cards have a multitude of protections built in for handling overheating and over power draw, the GPU will simply turn it's self off momentarily resetting the graphics driver which will crash some but not all games, Windows ill let you know it restarted the video driver as well.

While there may be a risk it's also not nearly as bad as "overvolting" may sound at face value given the circumstances.

 

So with that, I'm sure you're recommending overvolting, yes?

 

I'd say it's up to you if it meets your needs, I personally only recommend overclocking and the like when you hit a wall and need the extra performance, While I like seeing how far things will go, I don't typically run anything much over stock the majority of the time, just as/if/when needed but I will link this: P2657 3DMarks

Thats an overvolted & overclocked 460M.
