Ati Hd5770 Overclock

So i have this computer :

Motherboard : Intel DP55WB
CPU : Intel i5 760 @ 2.80Ghz
RAM : 2 X 2Gb DDR3
Graphics : ATI Radeon HD 5770 1Gb

All this in a very basic box with a few fans. nothing cooled with water or anything cool (see what I did there?).

I was looking inside Catalyst Control Center and saw an overclocking section.

I know it can be dangerous or unstable to overclock graphics cards so i'm just asking you any tip or recommended settings.

I like to play Battlefield 3 a lot and i think i could push my card a little bit further, it would be awesome :nod:

 

Overclocking creates a lot more heat and generally shortens the Graphic Cards life expectancy.

 

It is right that overclocking causes more heat and can shorten the life expectancy of components but not something that would be noticeable unless your really hammering it,in reality you would probably knock a few years off the life expectancy for some overclocking (say 15% and above) and when the life expectancy is usually in the region of 10-15 years (though this assumes the graphics card hasn't been run at high temps continuously, like above 75C), your way more likely to have replaced the part at least once or twice before that.

Personally I've never had much luck overclocking a graphics card, they are certainly more tricky than a CPU, my current GPU doesn't allow voltage changes in the BIOS from what I can see which would be needed if you wanted a significant overclock, additionally I would advise against enabling AMD Overdrive in the CCC it gave me nothing but problems.
MSI Afterburner is usually recommended.

I'm not going to give specific advice because this depends on the situation and equipment used and we are in no way responsible for any damage if you are overclocking, but some generalised advice below should suffice (this could also apply to CPU's by extension as well).

Don't let the temperature go too far above 75C at full load (i.e. Stress Test), this should negate some of the shortened life expectancy that can be caused by overclocking (heat).

Stress test for at least 15-30 mins while your overclocking and finding a suitable clock and voltage, try first increasing the clock rates (steadily say 10-25MHz at a time for GPU's and 100MHz for CPU's) with the default voltage and see how far it goes then obviously nudge it back once you find that stress testing causes the computer to crash, then increase the voltage slightly (0.1-0.2v should do, though this has to be within the Manufacturers minimum and maximum voltages for the GPU or CPU, you will have to look these up) and continue raising the clock speed till your happy or want to stop, don't worry too much about the voltage early on you can aim to save some power and knock the voltage back slightly once you get to a clock speed that suits you within the temps mentioned above.

Once your done overclocking stress test for an hour or so to make sure there are no stability issues and you should be ok.

And most importantly take it steady overclocking, patience is key.

 

Ok thank you, will look further into that.

Thanks for the great response
