Anyone knows a safe overclock

[Guest]

Hello does anyone knows a safe overclock for the Sapphire AMD Radeon HD 6770? would want to overclock it without breaking it.

You'll only break it by adding silly amounts of voltage to it. Run something like Unigine Valley or 3DMark and slowly bump up the core/memory sliders until you start to artifact. When you hit that point, back off a little bit and as long as your temps are fine there's your safe overclock

I just upgraded from the 6670 to the 970 (Massive Upgrade) and i should do 20% more fan power and 200mHz extra clock but I'm not sure so look for the temperatures in MSI Afterburnner.

Will try it and see how far i can get it.

And i will try your clocks and then bump it up if its ok temps

Just increase core and memory clock speeds conservatively until the system shows signs of instability.

 

As long as you're not adjusting voltage, you can't hurt the card.

Got 300 on the core and 250 on the memory.
