Should I be afraid to overclock my HD 5800 without a cooling unit?

post #1 of 4
Thread Starter 
I've had my rig for just over 3 years and have never tried overclocking my machine in fear of damaging it. Now though it seems that I'll either have to spend some money upgrading my gpu or overclock to keep up with today's newer games.

gpu: Radeon HD 5800
cpu: Intel i5
ram: 12gb Corsair DDR3
mb: Asus P7P55D Deluxe
power: 600w

I'm only interested in overclocking my gpu so any help or information would be greatly appreciated.

It must have a cooler... so, as long as temps are fine, then OC away.

Its fairly simple IMO. Download MSI Afterburner, enable unofficial overclocking, and start moving sliders (core clock and mem clock) up slowly. probably around 10MHz at a time. For example, my 5850 gets 850/1200 at 1.15V. There's plenty of tutorials for this.

Its pretty hard to damage the card unless you run voltages really high (in which case the computer should crash before any serious damage occurs?). And you probably want to run custom fan curves. Auto lets the card run too hot before the fans kick in.

OK thanks. My gpu has a fan and there are 3 fans in my case but no liquid cooling or extra fans or anything. I'll find some guides on the site and find some software. Thanks for the help though.
