I have come up with an issue on CG Miner which I'm not being quite able to sort through, so if any help would be possible.
I tried searching on the thread, and while some mentions to adjusting engine clock were around it didn't quite fit my situation.

For a while now I had been using CG  Miner 2.3.1 without any issues, but last night came up a problem where I couldn't seem to be able to adjust the clock speed below a certain value on neither of both cards (2x 6870). Wondering if it could be some odd bug I had struck on, I checked the thread, updated CG Miner, took the chance to update the video drivers, and on a new attempt I'm now able to adjust the speed of one of the cards to about any value, but not the other one.

I saw a mention that this could be driver related, but these cards are twins, worked always well before, but suddenly this came up even before I updated the drivers.

Any help?
