I read around that the ATI 5770 Series is good for overclocking, but i don't have any experience with overclocking so i would like some help on how safe is it to overclock it?

It is as safe as any overclock. It will run hotter and consume more power while delivering better performance. If you don't have overclocking experience run the Catalyst and there's an option to auto-tune.
That way the computer will do the work for you

So there is no risk of frying my GPU if i set it to auto tune?

And what are the avg temps and max temps so i can monitor it.

The auto tune is kind of soft on the GPU. It will overclock it a bit but not to extreme speeds.
About the temperature I'm not sure but I think anything over 80 or 90 degrees Celsius is dangerous

And how will this impact the FPS?

Slight increase, 5-10 fps tops. Depends on the OC.

Depends on what cooler you have on the card, but the best you can really hope for is a 10-15% overclock. You might get it to 950MHz on the core, and 1300Mhz on the memory, but don't try much higher. Slide to those settings in CCC and see if you get artifacts in games. If so, or if the card cuts itself off and then back on (don't panic - it's a safety feature - takes a minute or two) then lower the clocks by 10MHz and try again.

950mhz on core? isn't that too much? the maximum in the CCC is 960.

From the base speed, he is saying you can up 10 by 10Mhz. +10Mhz try the sistem for a while and over. but 950 it a lot idc :S

It all depends on your specific chip. These settings are the maximum that a decent number of people have reported overclocking to. Like I said, start there and then back down if the card doesn't like its clocks that high. You won't burn out your card - it will reset itself (freeze, then black screen, then pop back on with a message that says "display driver stopped responding and has recovered") if the overclock is too much. Back it down by 10Mhz on each until it stablizes in games.

I went to 950 and 1300 and played some BF3, 15 more FPS and max temp of 62.

That's great - great temps too!

Yea it's weird considering my case got bad airflow(only 1 120mm fan at the back and another 120mm on the heatsink) and i live in Egypt where it's hot already(30 atm) let's see how will it be comes the summer.

I noticed that there is an option to manually set the fan speed, it's unticked and at 35% atm should i edit that or leave it auto?

Leave it alone - apparently it's doing just fine keeping the card cool :)

Alright thanks a lot, you've been a great help.

I have an xfx radeon hd 5770 2gb, and I consistently run it at 950 core 1400 memory. Stable and it stays around 50c. Make sure you turn the fan on manual and force the fan to 100% at ALL times. I had it over heat once because the fan was speeding up and slowing down being inconsistent with cooling. After I set it to manual and 100% no problems.

I have gone as high as 955 and 960 core and 1415 mem with no problems, but you want to make sure you have lots of cooling consistent, if it is warm where you are especially during the summer, I would clock it back down to 950/1400.
