Title: [ADVICE NEEDED] = Power consumption using SMOS
Post by: yhingsy on May 24, 2018, 09:41:31 AM
Hello, I am after some advice on how to reduce power consumption on my small SMOS rig, mining Eth using Claymore-Eth-11.7. I am running:
1xRX570 Core = 1100 Mhz, Memory = 2200Mhz ~ 27.3Mh 1xRX560 Core = 1100 Mhz, Memory = 1600Mhz ~ 10.9Mh 1xRX560 Core = 1100 Mhz, Memory = 1900Mhz ~ 12.5Mh
And I use 290W without making any other changes.
So, in SMOS I reduced the powerstage to '5', and the Core undervolting is set to 820, and I am using.... 285W.
I haven't changed the BIOS or anything yet.
Is is possible to reduce the power consumption somehow?
Thanks in advance for any advice.

No, not for SMOS. for best wattage you must use Windows and overdrive'n'Tool.
Follow this guide, https://mining.help/2017/12/10/windows-10-mining-guide-for-amd-gpus-12-gpu-supported/
For the Over-drive. The whole reason why I switched off from SMOS, My RX580's were using 40 watts more per card because of terrible Linux OC tool controls. Same goes for HiveOS.

That's for that link - looks very promising.

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: 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 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 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: /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: /opt/rocm/bin/rocm-smi
