Huum its like little difference but more stability.

Not sure why some of the GPU produce different results, all are same really
Perhaps a strong downvolt, or a shortage of power supply, a poor riser. There are many reasons. My 588 runs 900mv / 850mv 1150 / 2100-2150 (depending on memory and algorithm) 24/7. I advise you to monitor the memory errors in the HWINFO. Ideally, they should always be 0, and do not run any garbage programs like msiab, they affect the stability. Also, the temperature of 74 degrees on one of the cards is super-high for me. I think this can also cause instability.
I advise you to set the parameter --gpureorder, this will simplify the setting and monitoring (Bus_id) of the cards using odnttool and gpuz
