okay MM921.mcs it is

I now have

Controller Firmware

MM Firmware
9211809-b4b3d00

so up to date I think

watts meter burnt at 1880 watt levels

so we will use the Vo

below instead of watts.

doing

--avalon9-voltage-level 1

api reads

Code:

Fan[6150]
   FanR[73%]
   Vi[1199 1199 1196 1196]
   Vo[4134 4153 4123 4110] Note still high due to that level 1 setting
   GHSmm[20527.05]
   WU[279617.92]
   Freq[771.00]

hash is 21143 will give 1 hour number
watts 1875 new meter
so I won't push it and test at level 0 next (no 2-15)

doing

--avalon9-voltage-level 0 note this is frodocooper's recommendation

Code:

Fan[5700]
   FanR[69%]
   Vi[1199 1199 1196 1196]
   Vo[4120 4138 4109 4096] Note drop due to 0 setting
   GHSmm[20496.36]
   WU[266040.52]
   Freq[769.85]

watts 1848
hash 20498 this is good about 90 watts a th. so far frodocoopers setting's seem to be more efficient then any number I can find.

so if you use api you can follow auto tuning and the -1 setting I used does not like to go past freq 780
It does get power down to 1816 watts question is will it settle over an hour or so giving good numbers and not lots of boots.

The auto tune is not working that well as least as I see it.

I set to

Quote

Voltage Offset(Default:0) -2

Minimum Fan%(Range: 0-100, Default: 10%) 40

More Options --avalon9-voltage-level -3 --avalon9-voltage-level-offset -2

so that number gets good power in terms of watts 1782

Code:

Temp[31]
   TMax[94]
   Fan[4710]
   FanR[56%]
   Vi[1200 1200 1197 1197]
   Vo[4078 4097 4066 4054] note lowest api number
   GHSmm[20444.68]
   WU[257729.67]
   Freq[767.90] and freq is 767 and it always try to go higher .

I would love to see if it gets stable using the -1 or -2 or -3
rather then it always trying to reach for a higher freq

Also it I do 1760 watts at freq 767

or do 1871 watts at freq 782 the eff is better with the lower freq so I would save power.

but it wants to keep pushing. I will leave it be at -3 for now.

power = 1779 watts

freq = 768 and it just booted

If you're on the September firmware, fan speed settings might not actually do anything or speed may report incorrectly. The October firmware says it's an update to detect fan speed. Stock, looks like these are 10% less efficient than advertised unless you consider their 0-20% power consumption increase. Should be advertised as 20TH/s @ 2000w.

[...]

That's awesome I never really put that together. I honestly only ever briefly considered it, mostly as a point for troubleshooting.

I'm wondering if they are working on a high-efficiency firmware for the 9 series as well. That is the name of the game ATM, mind you they would likely want to wait that out until after/if they release the mythical 941 - What I expect was the original 9 series numbers released.

I can't recall but with the -voltage-level would it be presumed that no command you are at a 0 essentially, then anything from 1-15 would be an increase? I get that at some point there will probably be a sweetspot for hash and efficiency in there, but in general won't this increase overall power consumption.

Evil beware: We have waffles!

You can look at the CGMiner API Log to record exactly what those voltage and voltage offset changes do. Near the top the line for Vi tells you actual PSU voltage at the PCIe connectors and Vo is the core voltage regulator outputs for each board. Vo will change with changes you make in voltage level and voltage offset.

Give things a 10-15min and you also see the miner freq it ends up running at. eg, my oldest one running stock gives

Code:

Temp[39]
   TMax[95]
   Fan[5910]
   FanR[72%]
   Vi[1195 1195 1188 1188]
   Vo[4068 4100 4129 4118]
   GHSmm[21468.46]
   WU[289826.24]
   Freq[806.36]
   PG[15]

As you change Vo you will see that Freq also changes as the miner automajikly plays with it to produce best speed results for those voltage settings.

'The right to privacy matters'

right now I am getting very good numbers with this setting

1811 watts and 19600 hash

I know it may say -2 is not included in the range for voltage level but it does lower watts more then 0 does.

in the case of the a841 we got some very good results doing this
in the case of the 851 results were shitty doing this.

I will do all 15 in range 0 to 15
I will do 10 out of range -10 to -1

I will keep fan at 40 - 100

Quote

Minimum Fan%(Range: 0-100, Default: 10%) 40

More Options --avalon9-voltage-level-offset -2 will not change

--avalon9-voltage-level -2 42 minute result 1850 watts and 18973 hash
--avalon9-voltage-level -7 next up

For fans, in More Options you can use --avalon9-fan to set both the minimum and maximum speeds eg. --avalon9-fan 50-75 sets min speed to 50% and max to 75%. That of course also applies to the A7xx and A8xx miners as well.

'The right to privacy matters'

so I did this:

Quote

Minimum Fan 40%
More options --avalon9-voltage-level 0 --avalon9-voltage-level-offset -2

I will get back with numbers

so processes look like this

Code:

cgminer --lowmem --avalon9-fan 40-100 --avalon9-voltage-level-offset 0 -o stratum+tcp://mmpool.org:3334 -O philipma1957.B:x -o stratum+tcp://stratum80.kano.is:80 -O canaan.80:1234 -o stratum+tcp://stratum81.kano.is:81 -O canaan.81:1234 --api-allow W:127.0.0.1 --api-listen --avalon9-voltage-level 0 --avalon9-voltage-level-offset -2 --real-quiet

and watts are worse not better. 1836 watts will play with it some more

And like the 721/841's can also set max freq and fan speed as well. Frankly, I never toyed with the settings when I got my first 2 back in Oct. Just plugged them in and let'em run.

Electrical engineer. Mining since 2014.

Cool to see you buying one and testing it out.

Does changing the value for --avalon9-voltage-level-offset make the power efficiency any better?

The --avalon9-voltage-level command-line option does not accept values of less than 0. In other words, your chosen value of -7 is an invalid value, and therefore may not be having any significant effect on your A921's efficiency.

According to lines 1643 to 1645 of cgminer.c from the avalon9 branch of Canaan's cgminer repository, the range of integer values that is accepted by --avalon9-voltage-level is 0 to 15:

Code:

OPT_WITH_CBARG("--avalon9-voltage-level",
set_avalon9_voltage_level, NULL, &opt_set_avalon9_voltage_level,
"Set Avalon9 default level of core voltage, range:[0, 15], step: 1"),

I therefore suggest using --avalon9-voltage-level 0 and --avalon9-voltage-level-offset -2 simultaneously if you're looking to run your A921 at the lowest possible voltage level.

'The right to privacy matters'

Edit 1783 watts doing 18123 gh

using this setting

--avalon9-voltage-level -7

decent about 98 watts a th but I am hoping for better

at stock it was 2020 watts doing 20500
it is a lot of hash for under 400 ssd but you don't get good efficiency.

this is an industrial miner needs 240 volts for 1 psu or 2 separate circuits for 2 psus if 120 volts
it is loud.
I am hoping for better firmware.
I will tweak it more , but I do not like results so far. It is very close to the s9i in efficiency but does more hash with more power.

13700 hash 1250 watts s9i on LPM

I may be getting better numbers with the second rasp pi firmware

I can drop watts from 2020 to 1731 with this setting

all other settings are stock

downclock results with first rasp pi are poor watts are about 2020 stock setting
I got watts to drop to 1800 but hash dropped more then it should of.

so say 2020 watts give 19th

basically shit gear on first attempt at down clocks.

I moved onto newer firmware will get back with numbers

stock was 2052 watts and 20 th on new rasp pi

first down clock used

watts dropped to 1932 will get back with a hash number

20.5 th so far so newer rasp pi seems better

1932/20500 = 94 watts a th not close to a m10 2400/34000 = 70.5 watts a th

but cheap 2 units = 790 plus psus say 1000 or 1100 for 40th

an m10 from li is 890 plus tax and shipping or 1200 for 34th

Do be sure that the cable is for both power and data... Very common issue is no coms because of folks using a charging cable that uses all 4 wires for power...

How common is that? Common enough that Blokforge now supplies the USB cable when you buy a AUC3 dongle.
