I think I need to break this out onto a second thread.

  Sent a pm basically I don't know why you got that number on kano.is

Can you monitor power use for the machine and do  a second test?

I am on kano's pool (kano.is).

Ah didn't know it was on nicehash. I remember reading this in their FAQ when renting some hashrate from them a while back. Too bad, I was hoping there was something interesting happening and there was something more to the "sweet spot" found on that frequency ;(

I pm'd him asking if he is mining with westhash or nicehash

when nicehash/westhash gets really overpriced and you set a number under the price your hash rates get weird.

right now nicehash is   over .0050 for a rental  so if you are renting you gear to them at a setting of .0046

two things can happen  you make the rental connection really solid and your hash will be lifted a bit.

there are other explanations

but I was able to do this today.

Interesting that your best hashrate occurs at your lowest max frequency. Any explanation? Voltages seem relatively close, varies only ~100 mV.

looks like we may be able to do this.

Posting some numbers for the past 5 days of my avalon.  What are the consequences of running a lower frequency while maintain same fan % and voltage?

the symptom  is the blue light does not light on the adapter stick.

you get zero hash.

so you don't need to replace the samsung you just need to have a spare 2amp 5volt on hand.

I did test all of them and all worked. Yan indicated it was more of a case of not working right at  the start

What are the symptoms of "This in turn underpowers the rasp pi which in turn under powers the little blue adapter." Does it hash slower? or Does it mean it won't power it at all?

Wondering if I should just replace the Samsung wall plug to be safe.

Got off the phone with Yan today he will be sending the replacement hashing board today  and 1 small blue adapter.

He passed along some info about the samsung walwarts they are rated at 2 amps but there are dud ones that do not put out 2 amp.  This in turn underpowers the rasp pi which in turn under powers the little blue adapter.  I will test this and demo during the week.

well as pissed as I was about killing off the 1 hashing board.  I got some good news and info to share about the 2980 or the 2880 psu's.

Right now I developed a low cost fan mod and really improved the sound and the power use for the fans.

I am running 2 ½ avalon6's and they are doing 10 amps on the 2980  plat psu.  that is 2400 watts but once I go to 10 amps my decimal drops off.

if it is a flat 10 amps it would be 2400 watts.  but it could be more like 2520 watts.

my hashrate is 6775 + 1801 = 8576   so  2400/8576 = .2798 watts a gh  better then the newer s-7's

of course with the amps at 10.5 it is 2520 watts and 2520/8576 = 0.2938 watts a gh  a hair better then the newer s-7's

The fan mod may not work at a higher load of 3 full avalon6's  so if I did not burn up the board I would not have tested this.

the fan mod cost about 30 for the first 2980/2880  and then about 22 for any after.

watts for the fans drop from 60 to under 25  ..


once I fully test this mod I will reveal exactly how to make it .


I will also show the install of the replacement hash board.

Yeah my evga 1300 is at 11.9 would like to push it a little bit more.  I guess I need a server psu with voltage.
Any good psu that you can ajust the voltage and that are 120v ?

this gear is voltage driven

12.2 is the safe max at gui  on the screen  and gets around 3450 to 3550gh

top setting is freq 500.

it is pretty good if you have  a slightly hot psu  say 12.3 or 12.4 volts at the psu  which will drop to 12.2 volts at the gui.

most atx are 12.0 to 12.1 and drop to 11.8 or 11.9 at the gui  you get 3200gh or 3250gh

I see that people have play with the voltage but what is the max freq at 12V ?

Edit: Look like we cant go over 500 

Yeah i'm glad you had an discount. Well deserve ;-)

Yeah it will cost me ,but  not full.    Full replacement price is about  500 + shipping.

It is only fair that I pay since I was running it at 12.7 psu side  12.5 gui side

Great news
