Is It Safe To Clock My GPU On Max Settings?

I have a 7850 and my case has four 140mm fans with decent airflow. One fan on the front and one on side sucking(blowing air onto my graphics card).Two at the top blowing out.(exhaust) When I start my pc and go into bios my cpu stays at a steady 10-20 Celsius degrees and doesn't go higher until like an hour. My gpu is at the lowest clock speeds possible and I was wondering if it would be safe to put it on max . BTW this is through amd overdrive.

Thanks for any help

Slide the power slider to 20% and ramp up the core/memory clock 50mhz at a time and run Unigine Heaven/Valley or a game to see if it's stable--if so, go back and bump the clocks up another 50mhz and test for stability again.

I'm sure your card can take all the sliders being maxed, but it's always smart to do it incrementally instead of all at once :)

I think you should increase 25mhz on core clock and then test it with Furmark and then you should test it out on a few graphic intensive games once you've reached a stable core clock you should move on to the memory clock and repeat the process.
This is what I did with my sapphire hd 7970 using the Sapphire trixx.Some people also increase the voltages on their cards which does results in much higher overclocks but I personally never touch the voltage.

Do NOT test with Furmark...it's in no way indicative of real-world use, and it's the worst benchmark there is because it unnecessarily stresses your card--it's a good way to end up with a fried card.

Use real world or real world equivalent benchmarks like 3dMark, Unigine Heaven/Valley or an actual game to test for stability and temperature regulation. Unigine Heaven is my go-to.

But yeah, ditch the 50mhz suggestion--bump the core up 25mhz, test, bump, test, repeat until unstable and lower it 10mhz and test--if stable move on to the memory clock using the same methodology.

Not all, it doesn't stress your hardware any more than any new AAA game would--unlike Furmark which unnecessarily stresses your hardware to the point that AMD and nVidia have made driver profiles to detect Furmark and throttle the cards down before anything bad happens.

Plus Unigine has a built in clock speed and temperature monitor so you can keep an eye on everything :)

One thing though: I'd recommend disabling Graphics Overdrive in Catalyst Control Center and downloading MSI Afterburner (doesn't matter if you have an MSI card) to do all your overclocking--it's much more stable than CCC and has usage/temperature graphs for monitoring. You need to go in the settings and set it to start with windows and apply your overclocking settings at startup otherwise you have to manually apply your OC every time.
