i have a 5x RX 460 mining rig, and since my mobo does not have a video output option, the video output is from one of my GPUs (i don't know which one, coz of the mess in there)
now where the other 4 GPUs are mining at 11.xxMh/s, this 5th GPU is only doing 2.xx Mh/s. Someone, please help me out here.
i read that since one of the GPU is also responsible for video output that might be the reason, but if it is indeed the reason, is there a way to bypass this shit?
goes out to all the good folks on bitcointalk.
it is a driver bug usually it is 4mh but you have smaller cards so it is 2mh
power off via the software on windows.

move to here with power off. then boot

if you get a block screen walk away watch a tv show for ½ hour see if you get a screen.
if you get a screen right away run your miners see if the 2mh is gone.
if the 2mh is still there
do this power off cleanly move the hdmi to 3 then boot.

if you have to do it with all 5 cards and if still has problem the next fix is
uninstall all drivers boot twice to clear shit
then reinstall all drivers.
[FIXED]
Hey thanks for the advice, i sort of did something similar.
so i realised that the card with the output was not on the x16 slot but another x1 slot on the motherboard itself (i have a 5 GPU motherboard, with one card on the motherboard and 4 attached to risers.) what i did was attached the output to the GPU that was hooked with X16 and i got equal hashrate on all.
Question 2:
SO my cards are MSI rx 460 4GB OC edition with Micron RAM, and i get 11.xxMH/s on each of em, is there a way to UP this a little, like 14?? (too much to ask?)
when i try OC-ing with afterburner (like moving clocks in sets of 20), there's hardly any change in hashrate but the the rig fore sure crashes after some time. Hence Afterburner is a no go but other suggestions are accepted. (core clock/default clock = 1210/1210)
