I got my dummy plug yesterday and started overclocking. While at it, I installed the blockchain driver, instead of previously installed 17.7.1.

Is it normal that fans run very loud now (even at stock clock speeds), while they were reasonably silent before?

Another thing - one of the cards doesn't want to be overclocked. They are 3x RX 570 + 1x RX460

-mclock 2000,2000,2000,0 -cclock 1120,1120,1120,0

The first card shows no increase in hashrate, second and third go to 28MH, and for the RX460, I have yet to find good clock values. Any sugestions?

Check if the first card is in crossfire
What do you have for memory on your 570's you should be able to go 2050 mclock and 1175 cclock on those if your dual mining else you don't need cclock higher then 1050.
Also for the 570's set cvddc 900 and mvddc 925 I have 3 570's with hynix and they are doing 29.3 and 66 LBR with 115w as reported by GPUz (I know it is higher then this by a about 30%)
if you are mining LBR set Drc to 20 if you are mining Decred set it to 25-30

Man, you are so usefull around here:)
If I understand "crossfire" right, it is when two or more applications claim control over the card. It must have been the case here, because I had to manually rise the memory clock in Wattman, and the card started showing ~28Mh. Do you know how to repair this? - How to tell wattman to release control:P

Two of my rx570's have Elpida, and one has Hynx ram. I only mine ETH so far and don't plan to go dual until I feel I know what I'm doing.

Crossfire is when the AMD Drivers tell 2 or more AMD cards to work as one card. The option should be in Wattman under the second card. Go to Gaming in Wattman and under one of the 570 cards you should find a setting Crossfire, check to see it is enabled if it is disable it.
