so short term 

sad so sad.

I have 5200 of them

be nice if they jump up.

is that 38 million usd?

yep   I just checked  this  morning.

and with the -1.4 setting I am at 2820 watts and  21900 or .1287  per gh  128.7 watts per th

now at stock or 0  I did push  14.9  and 14.7  which is 29.6   but that was with about 3700 watts  that comes out to  .125 per gh or 125 watts per th


The  psu  needs to beefy  to do 1800 watts I have a delta 2400 watt and a hp 2450 watt  that will do it.

the only  case it makes to burn power like that is if btc moons  to 12000 or more really fast

also the units ran hot at stock.

results over night:

So far I prefer the 841 over this 851

but it is nice to find that  numbers like -1.5 ,-1.4  do work to fine tune

I will setup -1.3  now and test for 12 hours.

Room is hot 90f  

-1.3  did boot I will get back with  numbers tonght

GAVE UP ON that setting it was about the same as -1.4

I am now on -0.9

and these are finally getting some where

http://solo.ckpool.org/users/1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje

about 27.1  th and around  3220 watts  in a 90f room

that is 0.1188 a gh or 118.8 a th

I taking these measurements to find a threshold

-1.3 or -1.4  do 21.5 to 21.9 at about 2825 watts  lets say .1289 per gh or 128.9 per th

I am looking to get  a steady 1500 watts at the meters or just under 3000 watts for 2 units

may be the -1 or -1.1 setting will work best.

based on my tests so far  power cranks up  but efficiency actually improved a tiny bit on this -0.9 setting.

I ran the -0.9   for about 8 hours  

topped out at 14th x 2 = 28th

I know I can push just a bit more.

If I go to 0  my meters may burn  as they did over the weekend.

so

 0.0 tested
-0.9 tested >  8hours > 28072 gh  1710+ 1661= 3371 watts = .1200 watts a gh or 120 watts a th  at 88f
-1.0 tested
-1.1 testing
-1.3 tested
-1.4 tested > 7hours > 21900gh.   1417+1398=2815 watts = .1289 watts a gh or 1289 watts a th at 86f
-2.0 tested
-2.7 tested >14hours >19300gh    1332 + 1309 = 2641 watts = 0.1368 a gh or 136.8 watts a h at 85f
-3.0 tested
-4.0 tested



-0.9   has the best efficiency  but runs hot at 43/92 and 39/88 with 100% fans.

will drop to -2.7 now  which did boot.  going to do an 8 hour test  






I have some test limits  I do not want to go over 1800 watts   so 0.0  does that  I won't be testing that setting again

think  14.9 th and 1800-1825 watt in a warm room is close

@ yankees  it does   14.6 to 14.9  at 0 setting   but uses  at least 1600 watts in a cooler room say 77 f

in a hot room  92f

 it pulled over 1850 watts on the hp gold  1450 psu
it pull  1790  on a corsair  1500 titanium  I shut that done asap due to fear of killing the psu

I killed one kwatt meter as they like to do under  1800 watts on long tests.

I did discover the -1.5 setting   this has me under 1400 watts  say  1350 to 1375 watts  on each meter  and around 22th

\\
early tests show as of today

If you want an avalon  I would say buy the 841 ..

the 851  seems  to need more power  as much as 1850 watts at  stock in a warm room

I am going to point the two to solo.ckpool  and try -1.4 setting

it does boot and does hash  be back in 2 hours with a report.


here are the 2 miners.

I would hope for 22-23th  at  2800 watts  or better

new meter link from amazon

Yes  I have been testing for about an hour.

I thought of trying a different approach to clocking the volts.

The new results are decent.  They also bring about a new idea others may want to try.

1) on the stock settings of 0           the 851  hashes as high as 14.9t but uses insane power  more then 1850 watts  which kills most of my meters

--avalon8-voltage-level -1
--avalon8-voltage-level -2
--avalon8-voltage-level -3
--avalon8-voltage-level -4

So I tried all of the above with the 841 and the 851

I like the results  on the 841  but the 851  hashes lower  and burns more power on those  underclock settings

So I started to think outside the box  and opened a whole new world  of clock settings

--avalon8-voltage-level -1.5       works   which means many others like that may work

my meters show 1350 + 1380 = 2730 watts  that ls .13  watts at the wall or 130 watts per th

at maybe 21000 gh which still sucks  but room is hot  90f

and it now opens  clocks like -1.1 , -1.2 ,-1.3, -1.4   to testing  many more for that matter.

+1 to -4   by tenths  is about 50  settings

2k and wait until maybe oct 31 for shipping = bad.

Fans are lopsided = bad

And if btc moons 4 s9i ordered today cost the same.

They do 56 th at the same watts per th as the b3 does 33th.

I can not  create a few cases where the b3 would be better

This is much the same as Avalon 851 it seems to be crazy dumb idea compared to the 841.

So b2 to b3 = dumb
841 to 851 = dumb

I have been breaking my balls trying to get a good setup of the 851s. Compared to the 841s

Step backwards 841=better.   This is first hand testing.

B2 to b3 I am reading specs and looking at photos. But I think it is going to be the same b2 will beat the b3

I asked mods to move this to alt coins.

  Every gigabyte card I owned with one exception sucked.

I would return them.

Now I know you don’t want to hear or read that but I had about six models of gigabytes

And they would drop my Afterburner settings and go full power much the same as you describe

btc price for rent on  nicehash = nuts!!

hey  we can hope a coin rallies.

I am holding BTG  it is at 20.16 = really fucking bad
I am holding ETH it is at 319.71

Okay they got a m3 using 28nm to do about 166 watts a th

The antminer s7 did about 250 watts a th so they were more then 30% better


So the s9i does about 96 watts a th on a 16nm chip

An improvement of 30% would be about 67 watts a th on a 16 nm chip.

Since they did 30% once they may be able to do it again.


Your idea of overclocking it is like me insisting to drive my Kia Forte at 162 kilometer per hour.

Or 100 miles an hour if American .


What I find interesting is if they succeed on the 16nm chip.

And the 7nm chip does 65 watts per then will they drop that to 45 watts.  but that would be the the m13 in 2020

Okay I have this squared away for overnight test I am pointing two units to solo.ckpool

Using -2 offset.

Doing about 24 th and cant measure watts on both units until I get a new meter.

The 851 seems to be okay and a bit more power hungry on -2

I need new meters to be sure.

Nice idea

LTC TO THE MOON!

if we stay under 50% cdf and we are 15.2%  cdf it is not an issue

So I attached a second miner and did setting -3  and something is wrong.

Going to try -2 setting

edit:
the mm files were different one was older then the other they are now both the newest one



both mm files the same and we are working!

I deleted this info as it was based on the wrong idea about the 851

The Correct info is the 851 is a stand alone miner that needs your psu.

---

this was wrong it is just like the 841  and does not use a built in psu

---

this was wrong based on an error

---

this was also wrong

okay at -4

--avalon8-voltage-level -4

settled in at 1260 watts on the corsair 1500ax tit model

have to wait on hash rate to settle it is maybe 12202.40

and 1260/12202 is okay  right near 103 watts a th

that is  spec as this is supposed to be a bit more power hungry

I am going to add a second unit and see what happens.

with 2 of three meters burnt out  and 1 left I can only meter 1 unit not both

3 meters will show tomorrow I can post power use then.

Finally some down clock numbers that look okay

under more options this setting

--avalon8-voltage-level -4

is using only 1305 watts

this is 841 info  I am going to try these two settings for the 851

--avalon8-voltage-level -4
--avalon8-voltage-level -5   lowest numbers      8500 hash at 950 watts runs very cool
