Re: GTX590 riches only 553 MHZ with 270.40 and 270.41 drivers
One card works fine! The issue arises when you attach a second GTX590. Then the cards work only up to the level 2 (553Mhz). I don't need of SLI and use the cards for CUDA applications. The power supply should be ok (recommended by Nvidia - AX1200). I had similar problems with beta 270 drivers under Windows, but solved by older driver, thus I think that this is really driver issue.
Someone with similar problems? Any ideas?
