time was a little long 12 minutes that may have dropped to 18.09

no another rollover we must have needed 20  or 25 minutes to get alh home.

Okay this pool has had 2 or 3 times of a lot of quick blocks.

which is what you hope for.

 what you hope against is long 85% or more streaks like this one.

this hot streak below I did really well

but on the bad side  this block below is back to back with current block

Now if you are new and buy 300th for 2 days and we hit a few blocks fast you do much better then normal blocks do.

of course you could get caught on a cold streak like the current one.

I mix my own hash with rentals here.  Once the new diff comes I will rent 100th again

Right now 18.14% is a rollover number.

That would bring us to 0.416 btc prize.

okay I just bumped my  dual psu back to 12.55
 see the hash at 3900 plus for each one
see the soft ware sensor at 12.4 and 12.2

the real volts are 12.55.

I have not booted just used the switch on the dual 2000 board from 12.23 to 12.55

I will do a cgminer restart now




and in theory see what happens. and it did restart

two screenshots show it is settling back in.  So I got a restart at 12.55 volts
 my guess is this as to your lack of restart.  the psu needs 5 to 10% higher to restart then settles in a lower draw.

So at 12.5 or 12.6 volts  the psu needs 1300-1400 watts at the start and it can not do it. It lacks the overhead.

My psu needs 2600-2800 at the start  and it has 4000 watt top end so it can do it.  It is simply a case of having the  1200 watt psu at 12.6  if it were a 1500 watt the reserve would be there for the start.

Ac compressor's refrigerator compressor's  use a starter cap for that little bit of kick start juice needed.  My skill set in psu's is not that good to wire in a startup cap.

it may have an internal pot

some do. 

  I personally never opened that psu..

Mine reboot with 12.55 volt setting.

What psu do you have?  and if there is a power outage does the rasp pi reset.

I get one problem with hard power of then power on the problem is at 11.7 12.2 or 12.5 volts and the rasp pi finds 1 of the 2 avalon's not both.  So I need a software reboot. but I do reboot at 12.55 volts

You were the first to call this.  Plain and simple.  

The bottom line is they have a big farm.  Has to be 180 to 225 ph or more.  The only hope is they take it on and off line for a reason.( still has overheating issue?)

The evidence is

Dec 9  --------- 174
Dec 10 -------- 212  peak test?
Dec 11 -------- 157

Dec 13 -------- 137
Dec 14 -------- 197 peak test?
Dec 15 -------- 185  two days in a row?
Dec 16 -------- 162
Dec 17 -------- 159

Well we missed I am going to wait for diff to change and rent 300th for a while on  Fri around 2pm or so.

I am tossing 100th right now!

It should run well at 12.6  as I run mine at 12.55 for 20 hours with zero issues.

top screen shot is a dual avalon  they both get over 3900 gh
on finsky's dual 2000=4000 watt psu with high volt setting of 12.55

that is possible as solder could be off.

The thread is 11 years old.  The safety info is okay but most likely  the psu's mentioned are not for sale or they have been redesigned.

I have yet to find a 2014 ,2015, 2016 model atx with a  pot for sale in the USA.  

Someone linked one but it was not available in the usa.  If you have 120 volt power you just won't be able to overclock.

There are more factors with the avalon  it has 4 pcie jacks  you need to supply 275-300 watts a jack to get close to  3900 ghs.

This means 16 or even 15 gauge cables  not many atx psu's give you 16 gauge cables.

Right now it has been hot again in NJ it is 55f  my garage is 87f my bedroom is 81f  so I had to lower the 4000 watt dual psu  from 12.55 to 12.23

I get 3500 for each avalon 6 and I get strange volt readings.

12.2 and 12.0  power comes from same psu's with same length cables

I am pulling 2300 watts to get  7150gh  about .32 watts a gh  I have  a lot of overhead on the psu's

say 2300/4000 = 57.5% used  if you are pulling 1100 watts  on your 2 psu's  you are 1100/1500 = .733%  and your psu may be 750 watts at 240 volts and only 700 watts at 120 volts  so you could be 1100/1400 = .7857%
 that is a safe number but may result in volts sag.

can you measure your volts?  and not the software one since I really do not trust the software readings mine should be = and they are not.

Think of people with old school light bulbs burning 60, 75 or 100 watts a blub.  An led bulb burning 12 watts with a chip mining 5 watts same light at 17 watts and  some coin back.  I could see this happening.

Good I tossed 40 or so at it for now and pool is at good hash rate for now.

Thanks we can use the help!

I am going to back off until noon then go to 100th again.

No they are not fire resistant but I have a fire proof pad on order and will add it and photo it for everyone



http://www.amazon.com/Automotive-Sound-Noise-Insulation-Padding/dp/B006LNWE7W/ref=sr_1_2?ie=UTF8&qid=1450358979&sr=8-2&keywords=engine+sound+insulation



I have used the material above and it is fire resistant on the foil side

Yes it is from a twin sized foam mattress top

 I used a six foot wooden board cut to 36 inch lengths.
I attached the boards to both sides of the psu with double sided 3m foam tape.

under the psu are 3 layers  2 rugs the the egg crate foam

over the psu is a rug

see the 36 inch wooden boards the egg crate foam and a  pair of rugs under it. actually of the rugs is rubber standing pad.



and here is a rubber stand pad over it  the air flow of the fans is full speed with out restrictions


another look at this top standing pad

It is a batch 2 rated for 575 freq!  Got lucky with it.

The Avalon 6 likes the 12.5 that the dual 2000 = 4000 watt psu give it on high setting

The s-7 seems to like the 2880 watter on whatever volts 2880 watt psu gives

I suspect the 15 gauge cables and the fact I am using 1300 watts out of 2880 watts is why the s-7 does so well.

here are results with the avalon 6's and the s-7




and sound meter readings

on the den/home theater couch  with garage door open--- 39.7db



about 46.8  a few feet from garage door



at the garage door 52.4



in the garage 59.7 pointed towards the intake spot



the outflow spot = 60.9  

lastly right at the intake of the 2880 watt psu 71.8 notice sound proofing i will post the sound proofing technique later today.
