1 of the 5 GPU in the 5 GPU rig is under performing.

[Qshall]

Hello Miners

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.

I get this issue sometimes, where I have cards that will randomly drop from 30mh/s to like 4mh/s. I usually just reboot and that fixes it.

Also, if you have to change clocks, voltages, etc: make those changes, close whatever program that you used and wait like 30s-1m minutes, THEN start your mining. I have found that works better.

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)
