What's the point of overclocking your GPUs if your use the onboard graphics? If you plug in the display cable to the mobo, the 5970s are not being used.
Did you raise the voltage of the 5970s when you overclocked? Because you should have.
Thank you Ihog !
yes , I used onborad graphic .
1.When i plug in the display cable to the 5970 i can do overclock ( change memory_clock , change fan speed , change core_clock ) but on this mode , under 99% GPU lode i got crash , also when i use default memory and core clock
2.When i plug in the display cable to the mobo i can't overclock ( everything locked or disabled also overdrive hidden in AMD Catalyst ) but GPU work in default core_clock and memory_clock without crash even i use 99% of GPU
So i need overclock my card when i plug in the display to the mobo
what is your advice ?
I'm sorry for my english
