I overclocked my GPU for the first time. I had to face a lot of instability at first. So, I decided to change the Voltage a little(+12mV). But, then instability popped up again.
Grey screen I mean. And then finally I found a permanent OC settings for my GPU. And it's stable now! So, I want to know more about my GPU's power limit. Is it alright that I maxed it out to 110%? And did I damage my GPU somehow changing the Voltage?
GPU Idle temp: 26-30
GPU temp at full load: 69-72

My current specs:
OS: Windows 8.1 N 64 bit
Processor: Core i5 4590, 3.30 Ghz
Motherboard: ASUS H97M-E
GPU: ASUS GTX 970 TURBO [TURBO-GTX970-OC-4GD5]
RAM: Team Vulcan 8GB (2 x 4GB) 2400 BUS (Currently running at1600 BUS)
HDD: Toshiba 1TB

The power limit varies depending on which GPU however the max for the 970 is 110%. NVIDIA guarantees that, unless you mess with voltage, you will not damage your GPU. Your GPU however is most likely running fine based off your temps. An important thing to remember about the voltage is that you aren't running that voltage constantly unless you check "Force constant voltage" in MSI Afterburner, which in your case I wouldn't. The voltage offset simply allows the GPU to be given more voltage at peak loads when it needs it otherwise it will only use as much voltage as is necessary to achieve the set clock speed. So basically you should be good.
