Hello all,
Is there any way to query Linux Ethminer hashrate while it's running? The only thing that I can think of is parsing its output, which is kinda tricky. Is there any simpler way?

Hi, thanks everyone for the advice and help. It really helps me to solve the problem. I finish optimizing all the GPU cards and measure their power draw. Per machine, which has 13 GPUs with 80% PSU efficiency, it draws around 1780 Watt, which is not too shabby. I use multimeter to measure the current and multiple it by volt. Again, I appreciate with the help, thank you all.

That's a good point. When you mentioned power factor, I just realized that when I read the power, I activated all machines, which drew interference. After I turned off most machines and left only 1 to be read, the reading said it was around 1760 instead of 1980. I use 80plus gold PSUs by the way.

that chipset setting I only manage to get it around 82watt power draw, with your chipset it only draws 72 watt. So it's very good.

@coyn,
this is very good, the power draw reduces dramatically, could you do it with other 3? There are 4 different kinds of chipset.

Best regards

@coyn,
here are my VROMs, there are 4 chip sets in my Google drive:

I'm using Linux ubuntu and PolarisBiosEditor to edit GPU ROM, so I use the term underwatt instead of undervolt since it only allows me to tune the power parameters like TDP and Max Power Limit. When I run the miner and read the watt output of each GPU using software read using "watch cat /sys/kernel/debug/dri/0/amdgpu_pm_info", they range around 80Watt to 110 Watt consumption depending on the GPU chip set. But when I read the power consumption via multi-meter, it reads around 1,980 watt.

I underwatt some of the GPUs, some of them I can't for some reason. So either my reading (multimeter or software) is wrong or my setting is. Is there any way that I have reconfiguration on the motherboard side that causing the overdrawn power consumption? Anyone is using Ubuntu or Linux?

Hello all,
I manage to build a 13 Rx 570 GPUs mining rig with Asrock H110 Pro BTC. When I probe the AC output with multi meter during ethereum mining operation, it consumes around 1,980 more or less watt of power. The GPUs themselves are consuming around 1,300 watt, but the rest like CPU and PCI risers are consuming 680 watt of power. Does this sound right? Or is there any other way to suppress the consumption?

Hello all,
I want to do profit comparison between mining using Nicehash or not using Vega56 GPU card. I use Whattomine profit calculator, and currently the best performance according to Whattomine, CryptoNight is having the best performance with daily profit around US$3.95 per GPU, whereas Nicehash Vega56 calculator yields US$2.22. Apparently Nicehash is mixing couple of algorithms like DaggerHashimoto, Equihash, and some small portion of CryptoNight, which ensues diluted profit.

Why Nicehash thinks that mixing those algorithm is the most profitable, whereas Whattomine says that pure CryptoNight will bring the most profit? Does this mean it is better off using the GPU without Nicehash?

well, I just need to set the display to 0.0 in the ssh session by executing:

Helo all,
anybody is remotely connecting mining rig using X11 forwarding with Nvidia GPUs? When I do X11 forwarding over ssh, I could bring up the GUI, but nvidia-settings command cannot detect any GPU card on the machine, saying:


any ideas? Or maybe possible other solution to execute nvidia-settings command remotely? My rig was a Ubuntu machine and tried to connect from a Windows machine

Hello,
I try to understand how the mining hardware environment is different between Bitcoin when centralized mining ecosystem is more encouraged compare to Zcash or Ethereum where pooling is more encouraged.

So is it true that when you have 2 separate rigs mining bitcoins, each individually not joining a pool, they could compete with each other, as oppose to mining Zcash or Ethereum, the 2 rigs join forces to mine together
in the same pool?
