so 8 cards on one mobo correct?

do you use a pcie splitter?

are all eight cards the same make and model? with the same ram?

sometimes a card has a different ram even if it is same make and model

i have 7 pcie and 1 m2 to pcie, all cards are same model and same memory (samsung) same sku, mb asus z270a

bios setting http://imgur.com/a/IAu7i (new i use last 1191 900mv) but it ignore it, driver from windows update 16.60

Also if i plug on card only it can't edit voltage that still 1000mv, with saphire trixx i can drop to 900mv something like claymore ovveride to 1000mv by it self

I build my first rig, i use rosewill case with 8 rx 480 nitro+oc 4gb

With windows i can do 31.6mhs (1190/2240) for card and miningos 31.3mhs the main problem it is power consume cause they will reflect into heat.
On window with one card only i can use saphiretrixx and drop power to 900mvolt gpu when i use all 8 gpu on window it dont' work it will revert to 1000mvolt and consume a lot of power.
I edited bios with max 1190 at 900mv but i dont' know why claymore override to 1000mv by it selft, also wattman override it selft on 1000mv when claymore start, i also tried ddcr on claymore to 900 but it ignore it.

I'm so hungry cause i can't drop mvolt of gpu +30 watt at wall for nothing and heat problem.
