Sorry for the Necro of this thread....
I was a little bored tonight and decided to try OC'ing my 6870 again.
I can't guartantee this will work for anyone else, but it seemed to help with my card...
My idea was to keep the ratio between the GPU and memory as close as possible to stock proportions. On the 6870 this resulted in a ratio of 1:1.167 (GPU/Mem, (900/1050))...
FWIW, it actually got me a little more on the clocks and managed to run for 5 minutes of Furmark torture test without any problems (I shut it down).
My clocks using this method were 1010/1180 (roughly 1010 x 1.167 for the mem), voltage was set to 1.27 using TRIXX.
If anyone else wants to try this method, I'd be interested to see if it gets you a little more on your clocks...
It helped me!![]()
