Experiencing problems when overclocking the ATI Radeon HD 6770 graphics card.
Experiencing problems when overclocking the ATI Radeon HD 6770 graphics card.
Hello everyone
For a few months now I've been using an ATI Radeon HD 6770 MSI 1gb GDDR5, but since upgrading isn't an option, I attempted to overclock it to boost performance.
The maximum settings in CCC are 960 for the core and 1445 for memory clock, so I set my core clock to 900MHz and memory to 1160MHz, out of caution not to push further.
After that, my screen would occasionally jump, so I increased the power from 1125mV (standard) to 1188mV (I found this adjustment helps when overclocking is unstable).
The temperature in full load stayed between 67-70°C, FPS improved by about 10, and the game ran smoothly.
However, the "jumping" screen issue persisted, sometimes causing a loss of screen and requiring a restart. After rebooting, the CCC settings returned to their default state.
I realize I might have made a mistake and haven’t found a clear solution, so if anyone knows stable overclocking configurations or fixes, I’d really appreciate it.
My specs are:
CPU - i5 2400 3.1Ghz
RAM - 8gb DDR3
Motherboard - ASUS P8H61-M LX3 R2.0
Power Supply - 500W
Sorry for the poor English, big and messy content – I hope you understand me.
It usually can't overclock and be stable above 850 core. That is just not the tier of GPU that can handle OC. No profit to OC this card whatsoever.
The original speeds are 800 for the core clock and 1000 for memory.
You have made significant increases right away! I’m puzzled that it functions at all!
Consider adopting a more gradual, step-by-step method. Perhaps start with 20Mhz and assess stability.
Yes 800 for core but 1100 for memory. I increased it to 20mhz for both, then tested custom clocks and if successful, raised it further to 20mhz more, not jumping instantly from 800mhz to 900mhz i.e., from 1100mhz to 1160mhz.
The setting is currently set to default, unless a solution is discovered later.
Sure, I can help with that. Just let me know what you need to focus on.
