Nvidia Geforce 820m : Clock dropped suddenly

[wataru junior]

Hi all.
Not sure what happened to my GPU.
I was overclocking my Nvidia 820m. I set the graphic clock from 625Mhz to 800Mhz (actually it's detected 720Mhz Min and 954.6 Mhz Max) and memory clock from 900Mhz to 1080Mhz. I was using Nvidia Control Panel and Asus GPU Tweak.

And then when I was playing game, for a while ( around 1-2 hours ) everything run well. Temp max is 74 C. And then I tried to raise the memory clock to 1100Mhz ( 2200 Mhz effective ) to get better FPS ( I thought ). Run well to for a while, but suddenly the clock drop fro all things. Graphic, Memory, Shadder core drop to below default clock. I really don't know what happened. I thought my GPU crash. So I try to put the clock to it's default clock, nothing happened. And then I restarted my Laptop. And it's back up normal again. So, what was happening to my GPU? Is my GPU damaged ?

Thanks for any advances.

Hi,

With overclocking it will come with a price. If it's a laptop make sure to connect it to it AC adapter to be sure it getting enough voltage to power the GPU. Next is to make sure that the PC is being cooled enough since it's going to be working double time as normal and it will heat up that fast. If all these doesn't work try updating your graphics card driver first to the latest.

Here's the link: http/www.nvidia.com/download/index.aspx

Uninstall the old driver first from Device Manager and same goes in Programs and Features. Once done you try overclocking it back to your preferred settings.
