The dev is working those feature into the program but for now use overdriveNtool by the guy on guru3d
Works great for all over clocking, undervolting and fan control. I mod all my bios with polaris 1.6 but if I need to tweak anything after I use overdriveNtool
I don't think we are talking about the same thing. I am running a geth node and want to mine local/LAN to my own node of any given coin. Not mine to a pool. It was confirmed to not be in 2.4, and has not worked with 2.5 or 2.6.
A command line like this, with geth running on a local machine:
EthDcrMiner64.exe -epool http://192.168.1.74:8645 -allpools 1 -eworker R1 -ethi 4
You see, I have to use Claymore for this...

Could you please share a simple guide on how to undervolt with this tool mate? I don't want to mess up my cards

I don't know if I should even do it, since for the first two weeks my rig is finally stable *fingers crossed* and I don't know if that would cause any instability, that's why I'm asking. It just much simple with those commands to do it and not go in-depth, that's why I asked, I don't mind waiting tho. Electricity is 0.06usd, so 100-150w won't cause me to lose much of the profit. It just bugs me, that the cards are getting hot and the fans, therefore, are working at 60%, producing a lot of noise.
It is super easy, so open the program, you can goggle -command lines to find all the strings you can use. You should know you frequencies you want to use and I have this in both my windows startup folder and at the start of each coin.bat:
cd\Users\Rig\Desktop
OverdriveNTool.exe -r1 -r2 -r3 -r4 -r5 -r6 -p1"570" -p2"570" -p3"570" -p4"570" -p5"570" -p6"580"
cd\rig\clay
EthDcrMiner64.exe -epool http://192.168.1.74:8645 -allcoins exp -eworker R0 -dcri 1 -r 1 -minspeed 175
pause
So I cd\ to the ODNT exe and then run -r on each card (be mindful of where you Intel GPU is at and don't call on it), that -r is a reset to default command so it takes each card in this one rig back to factory default, milliseconds lattr is runs the -p1, p2 commands which is load profile (p) on card number (1) "570" profile named 570. You can see I have a separate profile for the single 580 at the 6th slot.
The best part about this is that it resets all cards and then OCs them in half a second. All of them. And it does it when windows loads and when reboot.bat kicks in as well as whenever I load a coin to mine, as I start all .bat files with it. Global reset and OC works great to clear failed GPUs, in literally a second.
The Program itself its pretty simple, load the GUI, enter your settings onto one card, click to save that as a profile, that will create a config file right in the same folder, you can go in there and make other profiles with copy and paste and edit them faster then in the GUI, but either way woek, edit config file or GUI. That's how you make any number of profiles you want to call with the -pX function. You can have a profile for each card in your rig if you want.
These are my two profiles in this one rig, the voltages need a little touchup, kind of high:
[Profile_0]
Name=570
GPU_P0=300;750
GPU_P1=588;765
GPU_P2=976;956
GPU_P3=1065;950
GPU_P4=1130;950
GPU_P5=1192;950
GPU_P6=1233;950
GPU_P7=1268;950
Mem_P0=300;750
Mem_P1=1000;800
Mem_P2=2200;900
Fan_Min=750
Fan_Max=3000
Fan_Target=70
Fan_Acoustic=910
Power_Temp=90
Power_Target=0
[Profile_1]
Name=580
GPU_P0=300;750
GPU_P1=600;769
GPU_P2=918;893
GPU_P3=1167;1050
GPU_P4=1239;1050
GPU_P5=1282;1050
GPU_P6=1326;1050
GPU_P7=1366;1050
Mem_P0=300;750
Mem_P1=1000;800
Mem_P2=2250;900
Fan_Min=1125
Fan_Max=3500
Fan_Target=75
Fan_Acoustic=918
Power_Temp=90
Power_Target=0
And I have found that these 'hold' better then using watt man, afterburner, claymore command line, sapphire, any of them. Really rock solid.
If I could use Phoenix Miner with geth I would be getting 32 and 34.5 MHS on the 570s and 580s respectively but nope, I am suffering with Claymore still. haha.
