Claymore underwolting - best values for rx580 8gb nitro+

[joboy84]

Hello,

Have one RX580 nitro+ 8GB and I flashed the bios.

No undervolt was applied in bios, I must do it from Claymore miner.  
  
The value I put in claymore are :  

-tstop 85 -tt 65 -cclock 1150 -mclock 2200 -cvddc 850 -mvddc 850  

I got 30.300 mh/s on eth and 909 on Decr.  GPU fan is quiet, power draw from wall with GPU : 205w. 

On most tutorial the power consumption are between 130-150w.

Is it possible to keep the hashrate values while reducing power consumption? How ? What are your values ?

Driver : Official Mining Drivers Beta for Blockchain Compute. I have wattTool if needed.

Thank you.

try going up to 900 or 920 on core and see if it affects hashrate or not.  If you go too low, it'll crash, lock up, or produce errors.

rx 5xx series use more power than rx 4xx series, also silicon lottery, some rx 580 can do better than some rx 4xx series, so if your chip cant do 130 watts then you are out of luck.

My rig stats for your reference
8x Sapphire Nitro+ RX580 8GB (5 Micron & 3 Hynix)
23Aug AMD blockchain driver
Claymore dual miner V10.0
MSI AB beta 16
Core 1220Mhz, Mem 2175Mhz, core volt 950mv, men volt 1000mv

For dual mining: total ETH 244Mh/s + SC 4850Mh/s with power draw from wall 1500W

For ETH only mode: total ETH 245Mh/s with power draw from wall 1200W

right on.  That's exactly how it goes.
You can tell the quality you got on the silicon lottery via techpowerup.com GPU-Z.  It's called ASIC QUALITY.  70% is probably an average silicon, higher the better.  High quality silicon overclocks with less voltage.  Most of the time in mining, you get better overclocks and can run them on less voltage.

Ok then. Let's say I am out of luck

Even at 900/950 there is not a big change.

I let the values at 850. Have only 1% shares rejected on DCR and 0 @ Eth.

i have a combination of NVDIA and AMD, so in the bat file, how would i specific the undervolt settings similar in the command line and only to the AMD?

By creating two batch files one for the Amd platform and one for the Nvidia platform and running them simultaneously.

if your power draw at the wall for your computer with the gpu connected is 205 watts , thats mean your card probably pulling around 130-140 watts at the wall.
You can check easy your pc power draw if you have a integrated graphics in the cpu. Start the pc without  your rx 580 and measure the power draw connect your rx 580 start mining and measure your power draw , the different between that 2 number is going to be the closest number for a real power draw for your gpu.

Usually a simple built pc , with ssd, cpu, 4-8GB of mem, no extra cooling fans on idle is pulling between 40-70 watts...
