I see they have released version 20191103 for OpenWrt and 2019-01-03 for MM. Has anyone tried this one yet?

The changelog says following thing about the new MM firmware version -->

Code:

Version 9211901-faf6d80

Nope. The latest OpenWrt and MM firmware releases are still versions 20181011 and 2018-09-26, respectively.

fingers crossed maybe early Jan

It would really make ordering 1 or 2 more a lot easier choice

have you found new firmware for the a921

I would love to get it to be more efficient.

The default voltage level for the A9 appears to be 5, according to commit 6f0650e.

... 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.

We are not retail.

Good to know if I'm able to upgrade soon. Hopefully the group buy I'm in fills out.

Woah, 95C?

it rates to 100c so 95c should be good.

@ yankees

I will do a video on it soon

I ran these settings for 17 hours>

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

all other settings are stock

It uses 1700 watts
and hashes at 18700

that is 90 watts a th

^^ this is not the place to ask for comparisons especially no one has even gotten their hands on a s11. There are many many existing threads touching on Canaan's much higher build quality -- take a little time perusing the Hardware area and read them. As for shipping to SA, check Canaan.io to see if they have a closer distributor to you like cryptouniverse.

Some luck today

Code:

Temp[31]
   TMax[88]
   Fan[4800]
   FanR[58%]
   Vi[1200 1200 1197 1197]
   Vo[3991 4008 3982 3970] -------------- very low power use
   GHSmm[21302.50]
   WU[13594.97]
   Freq[800.12] ----------------------------- seems stable here

Quote

More Options --avalon9-voltage-level -9 --avalon9-voltage-level-offset -2

it is hashing and boot cycle has stopped. will need to wait to see hash rate on this setting.

the big change was new rasp pi image

Avalon 9 series buy through Blokforge @ roughly $110 more(i'll also need the controller/PSU etc) or bitmain S11?!! shipping to SA(South Africa) is another added cost factor. are these units(canaan) really rated or considered "better" quality than BM's comparison(ie S11)?

this firmware is a mess
can not do a lot of stuff with it

Perhaps, but unlike BM at least Canaan lets us play with it to see what happens Wink

@ frodocooper

so it is why those - numbers I used did get lower watts

Busy for holidays will play with the avalon another day

just downloaded the firmware you gave above

I will burn a microcard asap.

Voltage Level Offset(Default: 0) -2

Minimum Fan%(Range: 0-100, Default: 10%) 20

More Options --avalon9-freq-sel 0 --avalon9-voltage-level -3 --avalon9-voltage-level-offset -2

lets see what the above does

very promising it set freq to 0!

Code:

TMax[44]
   Fan[1110]
   FanR[10%]
   Vi[1215 1215 1211 1211]
   Vo[4075 4095 4065 4053]
   GHSmm[0.00]
   WU[0.00]
   Freq[0.00]

miner is very quiet fans at 10% of course 0 hash with a freq of 0

trying this next

The most recent OpenWrt firmware for the A921 is version 20181011. Canaan did not update their GitHub documentation to include this release.

There is no published changelog for version 20181011 at the time of writing.

It appears that the documentation for --avalon9-voltage-level in lines 1643 to 1645 of the avalon9 branch's version of cgminer.c may be erroneous.

Lines 25 to 26 of driver-avalon9.h from the avalon9 branch specify -15 to 15 as the accepted range of integer values for --avalon9-voltage-level:

Code:

#define AVA9_DEFAULT_VOLTAGE_LEVEL_MIN -15
#define AVA9_DEFAULT_VOLTAGE_LEVEL_MAX 15

The accepted range of integer values for --avalon9-voltage-level-offset remains at -2 to 1, with 0 being the default value, according to lines 29 to 31 of driver-avalon9.h:

Code:

#define AVA9_DEFAULT_VOLTAGE_LEVEL_OFFSET_MIN -2
#define AVA9_DEFAULT_VOLTAGE_LEVEL_OFFSET 0
#define AVA9_DEFAULT_VOLTAGE_LEVEL_OFFSET_MAX 1

The parameters in driver-avalon9.h are the ones that driver-avalon9.c refers to and uses during runtime. The above values are therefore the correct ones.

Tired will play more tomorrow.

So far frodocooper setting of 0 and -2 is best. 1870watts 20500hash.

Would love to set freq at 775 and watts at 1800

Well, along with voltages you can always try playing with the Frequency and/or turn off Smartspeed (Canaan's constant Autouning?) as well. Ref the available commands for More Options that look appropriate. Snippet of them from Canaan's A921 Github that Frodo found for us:

Code:

#ifdef USE_AVALON9
OPT_WITH_CBARG("--avalon9-voltage-level",
set_avalon9_voltage_level, NULL, &opt_set_avalon9_voltage_level,
"Set Avalon9 default level of core voltage,range:[-15 to 15], step: 1"),
OPT_WITH_CBARG("--avalon9-voltage-level-offset",
set_avalon9_voltage_level_offset, NULL, &opt_set_avalon9_voltage_level_offset,
"Set Avalon9 default offset of core voltage level, range:[-2, 1], step: 1"),
OPT_WITH_CBARG("--avalon9-freq",
set_avalon9_freq, NULL, &opt_set_avalon9_freq,
"Set Avalon9 default frequency, range:[25, 1200], step: 25, example: 800"),
OPT_WITH_ARG("--avalon9-freq-sel",
set_int_0_to_7, opt_show_intval, &opt_avalon9_freq_sel,
"Set Avalon9 default frequency select, range:[0, 7], step: 1, example: 7"),
OPT_WITH_CBARG("--avalon9-fan",
set_avalon9_fan, NULL, &opt_set_avalon9_fan,
"Set Avalon9 target fan speed, range:[0, 100], step: 1, example: 0-100"),
OPT_WITH_ARG("--avalon9-temp",
set_int_0_to_100, opt_show_intval, &opt_avalon9_temp_target,
"Set Avalon9 target temperature, range:[0, 100]"),

[...]

OPT_WITH_ARG("--avalon9-smart-speed",
opt_set_intval, opt_show_intval, &opt_avalon9_smart_speed,
"Set Avalon9 smart speed, range 0-1. 0 means Disable"),

In all cases, 'step' means increments of. eg for Freq. it shows 'step: 25' meaning 575, 600, 625, 650, etc.
Interesting thing is the built-in SmartSpeed tuning does not seem to follow that and as you've seen produces values not divisible by 25...

Also wonder what --avalon9-freq-sel <0-7> does? Pre-defined freq /performance settings?
So far that 20+THs @ 1,871w looks rather good and better than the A841 using -1 Voltage level (13.5+THs @ 1,300w)

edit: Corrected range for --avalon9-voltage-level to read as -15 to 15 per Frodo's findings.
