It already looks unreal. That is, on average, 261.5 Sol / s. This can be achieved at high GPU tact, but with a very high consumption of electricity.System without graphics cards can consume from 100 - 200 W (my platform with socket 2011 consumes  than 200 watts without graphics cards).And your configuration (without graphics card) consumes a safe 100 W. Are you saying that your graphics card consumes at 62.5 W per pieces and maybe even less? If you thought that today is April 1 - you're wrong  . Maybe it's still possible with R9 Nano (I do not have them so do not know), but I am writing about my SAPPHIRE RX480 NITRO OC + 8 Gb.
