[ADVICE NEEDED] = Power consumption using SMOS

Hi,
i used to lost almost one week to make SMOS undervolt.
i can tell: You can undervolt with SMOS.
Which tool you need:
1/ Ohgodatool
2/ rocm-smi

OK, this is steps: (this is 470s)
1/ Check your card core-clock states, mem-clock states, voltage states:

Code:

sudo ./ohgodatool -i 0 --show-core
DPM state 0:
        VDDC: 800 (voltage table entry 0)
        VDDC offset: 0
        Core clock: 300
DPM state 1:
        VDDC: 65282 (voltage table entry 1)
        VDDC offset: -26
        Core clock: 466
DPM state 2:
        VDDC: 65283 (voltage table entry 2)
        VDDC offset: -26
        Core clock: 751
DPM state 3:
        VDDC: 65284 (voltage table entry 3)
        VDDC offset: -26
        Core clock: 1019
DPM state 4:
        VDDC: 850 (voltage table entry 8)
        VDDC offset: -26
        Core clock: 1060
DPM state 5:
        VDDC: 65286 (voltage table entry 5)
        VDDC offset: -26
        Core clock: 1126
DPM state 6:
        VDDC: 65287 (voltage table entry 6)
        VDDC offset: -26
        Core clock: 1169
DPM state 7:
        VDDC: 850 (voltage table entry 7)
        VDDC offset: 0
        Core clock: 1060

Code:

sudo ./ohgodatool -i 0 --show-mem
Memory state 0:
        VDDC: 800
        VDDCI: 850
        VDDC GFX offset: 0
        MVDD: 1000
        Memory clock: 300
Memory state 1:
        VDDC: 65282
        VDDCI: 900
        VDDC GFX offset: 0
        MVDD: 1000
        Memory clock: 2000

Code:

sudo ./ohgodatool -i 0 --show-voltage
Voltage state 0:
        VDD = 800
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 1:
        VDD = 65282
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 2:
        VDD = 65283
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 3:
        VDD = 65284
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 4:
        VDD = 65285
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 5:
        VDD = 65286
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 6:
        VDD = 65287
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 7:
        VDD = 850
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 8:
        VDD = 850
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 9:
        VDD = 900
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 10:
        VDD = 950
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 11:
        VDD = 1000
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 12:
        VDD = 1050
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 13:
        VDD = 1100
        CACLow = 0
        CACMid = 0
        CACHigh = 0
Voltage state 14:
        VDD = 1150
        CACLow = 0
        CACMid = 0
        CACHigh = 0

and this is the code i was used to undervolt:

Code:

/opt/rocm/bin/rocm-smi --setsclk 0 1 4
sudo /home/miner/ohgodatool -i 0 --mem-state 0 --mem-clock 2000 --core-state 4 --core-clock 1060 --core-vddc-idx 8 --volt-state 8
sudo /home/miner/ohgodatool -i 1 --mem-state 0 --mem-clock 2000 --core-state 4 --core-clock 1060 --core-vddc-idx 8 --volt-state 8
sudo /home/miner/ohgodatool -i 2 --mem-state 0 --mem-clock 2000 --core-state 4 --core-clock 1060 --core-vddc-idx 8 --volt-state 8
sudo /home/miner/ohgodatool -i 3 --mem-state 0 --mem-clock 2000 --core-state 4 --core-clock 1060 --core-vddc-idx 8 --volt-state 8
sudo /home/miner/ohgodatool -i 4 --mem-state 0 --mem-clock 2000 --core-state 4 --core-clock 1060 --core-vddc-idx 8 --volt-state 8
sudo /home/miner/ohgodatool -i 5 --mem-state 0 --mem-clock 2000 --core-state 4 --core-clock 1060 --core-vddc-idx 8 --volt-state 8
sudo /home/miner/ohgodatool -i 6 --mem-state 0 --mem-clock 2000 --core-state 4 --core-clock 1060 --core-vddc-idx 8 --volt-state 8

the command :
/opt/rocm/bin/rocm-smi --setsclk 0 1 4 (it depends on your card, you need check your core-clock states and try to get best number. With me core-clock at state 4 is 1074, 1074 ~= 1060 so i choose it, if i choose higher states, power will increase from 8xW to 12xW) set a cap on your card and dont let it go to higher states.

This is the result:

Code:

/opt/rocm/bin/rocm-smi

With 580s cards, you can save almost 70W ( 15xW without this tune , after tune it run stable with 8xW)
I forgot, if you mine eth only power is 6xW for 470s cards
