Why doesn't the hashrate on my pool stats match with my miner?

My miner is reporting 604MH with 462 frequency. But the pool is reporting 570MH?


If overclocking to 462M without undervolting is already generating HW errors, does that mean I will have to OVERCLOCK my miner?

Very hard to answer.  Are you tossing thousands of errors hundreds of errors or dozens of errors.

In day 100 errors is no big deal

Mine indeed is tossing 1100 HW in 2 hours.

It's also very dependent on how the pool parcels out work, how much work is thrown away, difficulty settings etc

I'm getting 1% error rate, difficulty at 65k, pool reported rate average for the past 24h between 550 to 600; miner reports effective rate of 595 (due to errors ~1%) at 462M frequency

Did you undervolt or overvolt it? What does 1% error rate mean? My HW errors are numbers like 5k in 10 hours, still reporting 599MH average on stats panel. Pool panel (litecoinpool) reports 540-660 so huge fluctuation here. Feeling like mine needs an overvolt.

Got down to 625 watts set on freq 312
At 312 freq you can prob set the lowest voltage on all 4 chains (0xfe).
I did go to 0xf0

0xfe is the lowest voltage setting you can go to (0xfe is bigger than 0xf0)

I figured that and went back to try the lower voltage it does work.

fans  are nice and low. Dropped to 600 watts.
This allows two per psu. A bitmain aw3+ could run two at 600 watts.

/Users/macmini/Downloads/set_voltage

so I think that is the directory above

so I tried this

scp /Users/macmini/Downloads/set_voltage [email protected]:/config

and this came up

[email protected]'s password:

I could not enter  a password and if I hit enter it said wrong password

Have you tried typing in your password and pressing the enter key?
scp and other ssh tools will not echo a "*" or "." when you key in the password (so people cannot guess your password's length)

...

UPDATES -

Running my L3+ at 462M (20% OC)
All boards are set at 0xd0
Error rate is the wrong side of 1% right now

Effective hash rate at pool has been good - averaging 550-600

Power draw at wall ~ 870 W compared to ~ 830 W at stock voltage and speed

I'm now getting 15-20% more effective hash rate with only a 5% increase in power draw.

That may be good idea thanks. duh  it works

Have you changed the admin password on the miner? If not it's likely the same as the default on the S7-LN, which is admin.

the command I would use is:
Code:
scp /Users/macmini/Downloads/set_voltage [email protected]:/config/.

I just added a /. at the end of the scp command.

Been a long time since I did any Mac terminal

But give me a minute I will try

No worries. I'll be online for a while, PM or post here and I'll help

so what am I doing wrong?

Hey Phil,

Looks like you are missing a couple of things in the command you are typing on the miner. In jstefanop's first message:

USAGE:

Since this need to be run directly from the miner console, below is my attempt at a user friendly instructions for people not familiar with the command line:

Download the release binary on GitHub and copy it over to your antminer:

Code:
scp [Directory you downloaded tool]/set_voltage root@[your miners ip]:/config

ssh into your miner and cd to config folder (this is the only folder that is saved on reboot on antminers so we saved the binary here).

Code:
ssh root@[your miners ip]
cd /config

binary accepts two inputs in the format of:

Code:
./set_voltage [chain# 1-4] [voltage in hex]

bitmains voltage controller can be configured to change the 12v input roughly +/- 1v from 10v, and this is configurable via a hex range of 0x00-0xfe, with the default being set to the middle (0x80). Higher hex values (0x80-0xfe) will LOWER voltage, lower values (0x00-0x7f) will INCREASE voltage from the default.

If your not familiar with hex numbering, all you need to know is that they range from 0-9, then a-f

For example if you want to slightly decrease your voltage on chain #1 you would input:

Code:
./set_voltage 1 90

increments of 0x10 are good starting point to test a sweet spot for each board for a particular frequency. Lowering voltage until you get around 1 HW error per minute is usually a good reference “sweet spot.”

So lower voltages from stock in increments of 0x10 are 90, A0, B0, C0, D0, E0, F0 and higher are 0x70, 0x60, 0x50 etc. If you want slightly higher resolution just go increments of 0x08, so lowering voltage in lower increments would look like 0x88, 0x90, 0x98, 0xA0, 0xA8, 0xB0 etc.

The tool directly writes the voltages to the pic controllers memory, so all changes are saved even on reboot and power down. If you want to set everything back to stock, you have to set the stock voltage for each chain using:

Code:
./set_voltage 1 80
./set_voltage 2 80
./set_voltage 3 80
./set_voltage 4 80



When you download the file to your Mac, make a note of where it is since you will need to copy it to the miner using scp

./set_voltage 4 80



When you download the file to your Mac, make a note of where it is since you will need to copy it to the miner using scp and put it in the /config directory on the miner. Once you have copied the code to the miner you will need to login on the miner using ssh and then cd to the /config directory on the miner. Once you are in the /config directory on the miner, you will need to run the set_voltage command. The actual command is ./set_voltage, and you need to make sure that you use the leading ./, without it the command won't run. I'd explain why, but it's a linux thing, and not necessary unless you want to know.

I'll be online for a while, so PM me, or reply here and I can help you through it.

@ phillipma, try adding the "." (period) at the beginning of the command line.
