GT 520 safe overclocking numbers

[iTzGoNeViraL]

i have a gt 520 and would like some overclocking guidance so i dont end up destroying my gpu.

factroy clock:
graphics clock: 810 mhz
memory clock: 500 mhz
processor clock: 1620 mhz

i can overclock up to:
graphics clock: 1620 mhz
memory clock: 600 mhz
processor clock: 3240 mhz

i really dont want to damage this gpu, but need to squeeze more power out of it. keep the numbers safe please.

You wont be able to adjust voltage on that GPU, so clock away? Raising core/mem clocks alone won't do any damage to your gpu.

Also make sure its not set to auto apply clock settings on boot. That way if you hit an unstable clock it won't be applied at startup. Once you find the max clocks then allow it to be applied at boot.
