I have a Sapphire Radeon HD 7770. It runs very cool and quiet so I tried overcloking it. I used MSI Afterburner and turned the clock speed up from 1000 to 1100. I let Kombustor run for 15 minutes to make sure it is stable and cool. Everything worked fine, but when I ran Battlefield 3, it crashed within 5 minutes and gave me a blue screen. I tried this multiple times. It always worked fine in Kombustor but crashed in Battlefield.

In Afterburner, the only thing I changed was the clock speed. I did not touch the core voltage, power limit, or memory clock. I also left the fan on automatic.

Any ideas what is causing it to crash? Here are some other specs in case it helps:
-AMD FX-6300
-ECS A970M-A Deluxe
-8GB HyperX Genesis

Overclocking isnt a science so were one card may overclock well and run stable a identical card may crash .... also other factors need to be considered such as case cooling and the graphic cards gpu fan ( and if its dirty )
the amount of performance you will gain from overclocking the HD7770 is minimal at best and the downfalls far outweigh the positives .... i personally would leave it at stock ... the HD7770 can acheive around 35fps to 40fps at stock speeds so another 3fps wont be noticable but will place stress on the card
granted adding voltage to the gpu may help but voltage creates heat which in itself can cause crashes ... so the solution is :
1) re-evaluate your cooling and add/replace fans in your...

Things such as Kombustor are only tests and can quickly find errors, but real WORLD games such as battlefield 3 truly test your gpu.

The most accurate way to test an overclocked gpu is playing a full game of bf3 without crashing. Benchmarks and games are entirely different on your gpu.
If you want either decrease the clock or upp the voltage depending on your temps (do not go above 1.2v)
Also don't jump in 100mhz jumps, go up in 20mhz to 30mhz jumps and test.

-good luck

Try this, it might work.
First of all you need to TOTALLY remove all the old drivers. Use this link.

Note:
Select the respective company(i.e Nvidia or ATI) drivers to be uninstalled.
Use clean and restart option.
And then install the new drivers after rebooting.

After re-installing the drivers, OC it slowly.

Sounds like you are unstable. Like Anonymouselite5 said, you can run a stress test and be fine with an overclock, but playing an game will crash it. You either need to bump up your voltage, or tone down the clock speed.

2) buy a 3rd party graphics card cooler ( http://www.arctic.ac/eu_en/products/cooling/vga.html ) ... this will reduce load temps that will help
3) leave at stock
hope this helps
