Undervolt MSI RX 580 4G Elpida

[cleverserge]

Hello, Everyone

Got new 6xMSI RX 580 4G Elpida. Timings were set from 1500. But I can do nothing with power consumtion. It is too high (one card+system 300W on th wall). In MSI afterburner core voltage control is inactive and shows 0mV. I use 17.4.4 drivers. Any advance is appreciated.

Thanks

No shit? When did that version come out? I know my 580 8G has the new controller, and it didn't work for me.

Got me.  I plugged a Kill a Watt into my 6 MSI rx580 4gb cards and it was doing 1200 watts at the wall so I tried reducing the core v.  Still trying to get the hang of under volting.  I have 6 MSI rx580 8gb cards and it work on them also.

Well it was 1200 before I started tinkering with it.  At those settings in the image it is around 1130watts.  What power limit % would you suggest?

Power limit I tend to keep high - I don't ever want the card to throttle because of using too much power (unless it was over spec of the slot & connectors.)

Core clock can cause the wattage to change, though - to confirm, note wattage draw at the wall, adjust ONLY the voltage, and check again, then compare.

Ok i'll keep the power limit as default (0%).  I was going to leave it at -48  over night to see if it remains stable and drop it another 50 after that. 
I am using the bastardized driver mix of 16.9.3 and 17.4.3 to get 6 to work in win10.  Would that have any effect?
