MSI RX470 4gb hashrate falls to 4Mh/s (one of 6 card gpu rig) (ethereum)

[otto_diesel]

MSI RX470 4gb   hashrate falls to 4Mh/s   (one card of 6 card gpu rig), 2 samsung 4 hynix, (problem with 1 samsung)



What can be the problem ? what is wrong with it ?

MSI; core clock 2100, mem clock 1125  /2 samsung
       core clock 2000, mem clock 1125  /4 hynix




       note: hynixs were 1900 on msi afterburner 26.2 hashrate, then i make it 2000 its 27.6- 28.2 mh/s  (not very stable but more good than 26.2)

and it mined for hours and dropped mining in 23mh/s (all of 6 cards)

TOTAL nearly 140 MH/s

and i make again it 1125 - 2000 and 2100 and mined for ours, and now all cards is okay and stable, but one of samsung falls to 4 MH/s (stable on 4mh/s)

TOTAL nearly 140

what can be the problem, any one have idea ?

Thank you !

Plug a monitor into it

[philipma1957]

yep   this is a well known bug

[adaseb]

IF you need your monitor then, start up the rig, plug monitor in, start mining, unplug monitor.... should continue running until restart.

Very annoying hence why I still prefer AMDs older Pitcairn, Hawaii, Tahiti GPUs.

thank you,


Additional info: i have no monitor in home, i was use teamviewer for control the rig. but nova days it didtn't start when i press the button,  2 internet light on internet socket on mobo were turned on 'constantly' , and not 'winking' (normaly its winking on my mobo when its working.)

and teamviwer dindt start. and Dismantle tv from the wall. and brought tv near the rig. when i plug in to HDMI cable to rx470 socket and turn on the rig. its working. TV and teamviewer (when reset or turn off-on without television its no working, it doesnt start)

 is it relevant with my problem?


i cannot use tv again, because dismantle it from wall takes nearly half hour and its hard.


  is there any one have met before problem like this,


  sorry about my english, thanks for good informations

Even a KVM switch works so i found out, i bought a switch to avoid buying a new monitor guess what I'm back to using windows for a week with out one issue yet ... I was having dropping hash rates , boots up wouldn't happen unless i plugged in a monitor even some Linux based OS miner i use wouldn't boot right unless i plugged in a monitor ..

I've been wanting a KVM switch for while now so i bought one ..to my Surprise so far it has cleared up my issues, I'm back to using windows ..which I prefer over all other OSes ..

but a kvm switch fix this problem when its alone ? because i have no monitor and tv is far away from rig

I use a kvm switch  and a cheap monitor.

any issues with any rig it is fixed.

what is your country?

I will attempt

 to find the cheapest fix for you  the cheapest fix may be a kvm switch and a cheap monitor.

how many rigs are mining for you?

[xxcsu]

.... The cheapest fix would be the Display Emulator for 8-12$ ....
don't buy a monitor/kvm switch if you dont need it
