with your recommended settings, I get this. The temperature is a little higher than before (66C vs 64C) but the consumption a little lower (from 79w to 75w).

it shouldnt be higher since you reduced the core clock a bit and the watts reduced, that means less power is drawn and less heat.
Autofan , you can use it if you like. basically you set the desired temp and the fan changes its speed to reach the temp. that means it may run faster all time if it can not cool the GPU enough. Also if it can easily cool it and reach the desired temp , it will slow down for some time until the GPU heats again. but i personally prefer to set it at stable speed and this way the temp of the GPU wont vary.
About watts the lower the better but every card is different. Mine does 30.80 MHs while consuming 95 watts and its RX 570 Asrock with samsung memory. your card does quite a great job here pulling only 75 watts power.
Make a test and remove the VDDCI and check if it returns to 64 degrees or its just hot where you live. but i dont think it will make any effect. still it seems the card is hot. mine is running 54 degrees with 60% fans and is pulling 95Watts with core clock 1131 
and mem 2080. Find the differences, your core and mem are higher and you get 20 less watts and almost 1 MHs more.

Its allways a compromise with wattage/hash/temps…autofan or like TRM --fan_control= conf is good options with temp control. Have had this rig all +32…33mh with high wattage/temps but now i have pushed temps and hash down, with totoal 25gpus that is a significant difference in total consumption…its a different game if u dont pay too much of electricity. After all…ts not too much u loose in profits and u get stable rig…set and forget … lol
can you share a screen shot of oc setting pls
here are my settings. the card is RX 570 8GB Asrock ( fukin power hungry )
it consumes 95W. the 245 that you see is because i inserted also the PCs watts and the PSU conversion rate of power and it estimates total use of 245 watts.
Most RX 570/580 cards run well with 1150 core clock , 850 core voltage, 2050-2150 memory clock.
Hi,
Could you check these settings? I can’t find a solution. I don’t understand why it’s 5MH now but a week ago it was 15-16 MH. Polaris 1.7.5.0 modded.
1250/900 ? 
GPU looks like throttling
What are you trying to mine with this card?
ETH, for testing and learning purposes. not for income.
You cant mine eth with 4gb card
Zombie mod worked for some time but i dont think it will more. But the thing is with thos card you can mine raven coin or ergo and earn more than zombie mod eth.
i have the same gpu with the same problem did you solve yours?
Hello everyone,
I’m new at this mining things so I don’t know how to set my RX 580 (8GB) OC settings, I can’t set the voltage below 100W. Can you guys help me about it please?
You are touching the VRAM voltage ( VDDCI ), not the GPU voltage ( VDD )
The GPU consumes much more energy that VRAM. You need to lower its value to go under 100W and mary it to ‘Agressive undervolting’

Thanks! Which value should I write for VDD?
Thank you very very much it works!
After messing with a whole bunch of settings and flashing the BIOS. This is the best I could get. Not bad, considering where it started.
Also… NOTE after updating to the latest HIVEOS software ( 0.6-209@210822), the miner would not accept ANY shares (would not reject any either)! So i downgraded back to 0.6-208@210818
If you turn core clock down it helps a little I have my card down to 84 watts mining eth my 480 is at 76 watts. For some reason I can undervolt the 480 with best results my overclock is cclock 1120 dpm 3 vdd 850 mem 2020 mdpm 3 pl 80. I get 30-31 mh on eth at 85 watts and on raven 15.08 at 107 watts
