Overclocking 4870 from 770 to 800 will cause crash

post #1 of 10
Thread Starter 
Hey guys.

I have a Powercolor Ati Radeon 4870 1 gi ddr5 card.Problem is when i Oc the card to 800 Mhz(using ATi Overdrive)and when i play games it'll crash after some 10 mins.this has been happening only very recently.When i bought the card a year back,i had immediately OC'ed it to 800 Mhz and experienced no Crashes then.


My catalyst version:10.12(i have tried this in many catalyst versions and even in windows deafult driver for 4870,still it crashes after the OC)

Well,

Chances are it's just getting old, the problem in is when the card heats up the solder in the PCB heats up and fractures. Chances are since you've been running this card at this speed for a while it could probably caused microfractures which has now made your overclock unstable.

You have 2 options, drop it back down or bake the card. Baking the card imho isn't really an option, it's used to revive dead cards as a last resort, not to make your overclock stable.

Or perhaps your power supply is degrading. Ripple current would cause enough fluctuation to make an overclock unstable.

True, what PSU do you have? If it's a good quality one I doubt it's that though.

i have a cooler master 600 w PSU.would a GPU-Z screenshot help?as far as i know.gpu temps average around 63 C when running a game

I doubt it's the PSU, they aren't great but they aren't horrific.

I'd say the card is just getting old.

just get a new graphics card. Your one will be outdated soon anyway

The 4870 performs nearly as good as my card. What's the point in replacing if he doesn't need the extra GPU horsepower?
