Phoenixminer is possible stale shares which GPU - >> total ?? and gpu 1 /? gpu2 /? gpu3 /? etc. It is easier to change settings of the GPU that causes the most stales.
http://www.resimag.com/p1/e9d607fe24.jpegIt does this already. x,y,z are assigned stale shares per each GPU that caused it.
GPU 1 shares 10/x, GPU 2 shares 10/y, GPU 3 shares 10/z
I press the x / y / z keys but on the screen I get no info about STALE share per GPU unfortunately, please tell us a bit more efficiently
