Gigabyte G1 970 Overclocking numbers

[charper732]

Looking for results that others have achieved when OCing the G1 970 card.

I have OC'd mine but not exactly to my liking. I am currently at core 1493mhz and 7856mhz mem
I had in my head that I should be able to achieve north of 1500mhz as everywhere i read thats what people are getting and seeing how this is a binnd card i didnt think that is too hard to achieve.

The highest stable clock at +136 core and thats with no voltage increase. I get no articafts but the Open GL windows timeout error comes up. I tried increasing voltage by .025 but that did not help at all and power is staying around 98% with temps at 75.

I did end up having to increase voltage to get past 700 mhz mem clock

I had a suspect PSU so I bought a EVGA 850 supernova to make sure I had a steady power flow.

I just find it odd that I get no artifacts just an Open GL error.


EDIT: at +.025 voltage im running mem at +1100mhz stable and still adding. The memory on this thing overclocks like a champ.

I was running 1515 core and 7800 memory and that was stable in heaven benchmark.
I was getting some odd lagging in Diablo 3 so I lowered it to 1490/7700 and I haven't seen it since.

No idea if the two were related but it's possible. Also this is a very loose overclock, I didn't play with memory much or try to tighten down the core clock.

Edit: Have you noticed any coil whine? I didn't notice it until after I started OC'ing, and either way it's pretty quiet but I still intend to call Gigabyte about it.

post back when you have more time to play with it. I'd like to know what kind of clock you get with voltage
