4x shappire R9 280x vapor-x GPU 0 always faster than GPU 1 2 3 ?? memory swap 40 gb have 3x bios 015.42, elpida 1x bios 015.41 hynix. Does anybody have an idea?

You did not post the clock settings. perhaps gpu 0 has better clock settings than the rest.

use asrock 970 extreme 4 windows 7 + 2x pci-e powered risers for the small pci-e slot
all stock, can not use any amd tool, it says driver not installed.... Driver install many time, ok in windows. use tech power gpu z
amd monitor no info

windows 10 the same, slower speed for all gpu,s gpu 0 faster, no amd tools

amd driver 15.12 not possible to install stays on 2%
missing windows update's??? or anything? use 16.10.3

GPU clock all the same

No info

Its fine. hashrate are usual with your clocks settings.
