All work and allow safe running in a hot room.

They all drop hash and watts try -3 or -4

I got some more avalon 841 in and a sorcerer psu  and will do a few tests with them.

I took some photos of this test bed setup note room is 83f but it is taken on top of a tv setup and reads high.  I placed the psu to get cooling from an ac vent.

watts 950



temp is at 6 foot height about 9 feet away from gear



gear note corsair ax1500i psu



note ac vent which does push some cool air towards psu




8500 using 950 watts is about 0.111 watts a gh the point of tests like this is to show work arounds it means you could use any 1200 watt atx psu in a pinch even with 120 volt power.
it also allows for use in a hot space during the summer.
this gear should not have overheating issues at this setting if you area to mine is fan cooled  and runs warm in the summer  this setting should work for you.


here are the five under clocks  that work for me

--avalon8-voltage-level -1
--avalon8-voltage-level -2
--avalon8-voltage-level -3
--avalon8-voltage-level -4
--avalon8-voltage-level -5   lowest numbers      8500 hash at 950 watts runs very cool


the 2 below did weird shit and acted like overclocks not under clocks
--avalon8-voltage-level -6
--avalon8-voltage-level -8

nice website for an idea but info is off.  the avalon  is about 1200 now. not 2000.  It needs to be updated

yeah  I always make it a point to blowup  any and all death stars.

I am running 35th over the weekend  3 new avalon 841's

This forum attracts spam and shit posts  due to the simple fact money is made from cryptocoins.

First suggestion  is rename  to cryptocointalk.org   it may be for sale.


Frankly the alt coin  = every coin but BTC  is  a limiting concept.

about 50 days

ramp up  time is 5x  a 100% block  a 100% block is about 4,200,000,000,000 shares

our pool does that in about 10 days

so  if the first 10 days of mining you are ramping up from 0 to 20%
the 10 to 20 day time period you are ramping up from 20 to 40%  of a full share
the 20 to 30 day time period you are ramping up from 40 to 60% of a full share
the 30 to 40 day time period you are ramping up from 60 to 80% of a full share
the 40 to 50 day time period you are ramping up from 80 to 100% of a full share.

And run them gentle like freq 359 with lowest volts

It is not hard to explain on a YouTube video with visual props.

It is harder to explain writing on a post format.

this pool requires you to stay put to get full shares.

3 days are nowhere long enough to get a full share.

we have enough hash to make 3 blocks in a month.

or a block every 10 days.  5 blocks in 50 days.

once you mine for that long your shares will be full.

3 days is 3/50 or 6%  so your shares are only 6% of what they will become.

note all of the above presumes your hash stays at 1 T1 and the pool stays around 20 ph.

about 400,000,000 million gpus  can mine coins at a profit

even if ½ are on big farms and ¼ are on small farm  that means at least 100 million pcs across the world can mine at a profit. and at least 50 companies sell pcs or gpus with 1 year to 3 year warranties
that is decentralized .

1 asic seller or 1 asic sellers  selling gear designed to break in under a year is not decentralized.  and if ½ go to big guys ¼ to smaller guys and ¼ go to little people with 1 or 2 asics you simply kill off customer base.



It is easy to justify buying a pc  for 2k that earns 2 bucks a day while you sleep.  no gpu mining you buy a shit pc  for 500 or less.

Asics did not make 2017  the best year in mining profits gpus did.

 I sold off some more gpus.

 Still have 18 1080tis left  I did buy a lot of LTC3+  I will not buy any asic on a coin being attacked. such as z9

I rathe use btc asic or ltc asic gear.

If I believe in a coin such as zcash I would buy some coins .

I will chime in it can give multiple voltage for each board.

Not mutilple freq.

So this means you can choose  freq 400 knowing the three boards are under tasked or choose say 425 and tossing lots of errors on the poor board

btw don't volt the bad board that high you will just burn it out.

personally i would swap it to a different L3+  but if you have 1 l3+ that is not an option.

Update  it was deleted.

As is the attack on gpu mining  by asic builders.

The most successful year ever  2017  was on the back of gpu mining  and the asic builders attack the gear that  created that success.

 Do I think zcash is a bad coin do i think they are scum?  I did see your youtube video.  It makes a good case.  I will wait and see what zcash really does before I decide they are scum or a clever fighter of the asic attacks on them..

Long term reliability could make the t1 better even if they don’t break often.

Of 22 s9 purchased from batch 1 up to last dec2017 I had about 10 boards and two controllers die.

Time wise that would be just under 22 months time.

So in 22 months if no boards die the t1 looks better.

Btw the t1 now has caused bitmain to offer more firmware control over your gear.

That came after ck did firmware here giving three speed settings and I mentioned that made the t1 a viable choice over the s9.

So all owners of s9s now have access to better firmware.  As of April of 2018.

I am sure those that use it won’t be donating to ck or Halong but fact is that is what happened.

@ op

I would love to answer your pool but your choices are very limited.

Asics are being used to attack gpu coins.

I see that as do the rest of us.

So now the equihash algo is under attack.  By maybe two different asic miners.

So the leading coin is zcash and they are dancing bobbing and weaving around do we fork or not fork.

I would say he should not decide or tell anyone what he will do.
Then when the gear from bitmain ships he should fork and make the announcement that they won’t fork a second time if new asics are made.


Then in six months when some asic builder attacks zcash2 with asic2. He should fork again saying I changed my mind.  And I now have three algos ready for any new asics attacking zcash3.

This is a war asics against gpus.

And gpus losing the war means death for all coins in the long run.  It goes far beyond zcash.

Cryptocoins best year ever was 2017 and gpus were the driving force.

Not asics.  Then in 2018 gpus were shut down by gpu builders prices got jacked asics mined coins on the sneak.

All the gpu networks grew in Jan feb mar yet not many gpus were sold.  So zcash leaders should not be standup transparent deadly  honest.  Then need to bust a move that hurts the. Users of Equihash ASICs more then your pole.

Then need to keep us guessing.

I have never seen something that blatant be allowed to stand .

It makes me think there is a lot more to the picture then meets the eye.

This is it in a nutshell when I started Mining btc network was 21,000gh

My 21gh was 1/1000 of the entire network.

We made blocks at 144 a day on average just like we do with 30,000,000,000gh

I would need 30,000,000 gh to have 1/1000 of the network.

The network would be just as secure with 21,000gh in gpus if growth was capped to 1% per jump.

51% attacks would be stopped.

So many ways to do well in this game.  Other then asics.

More then 100,000,000 PCs have a gpu that makes money if it mines.

Why destroy the easiest way to get mass adaptation of crypto.

Only hope is newer coins and algos that allow gpus to earn money and spread adaption of cryptocoins.

What is your room temp?

What is your voltage?

A hot room and lower voltage like 220 vs 240.

Will affect that psu.

the fan swap did help me a little.  3-5c

anyone pointing to nicehash?
