You must have cheap electric.

I'd need a new mortgage in order to run one of those for any length of time. The UK offically has the worlds most expensive power.

Interested to see your set-up once you get it running though.

Good luck!

it is going to a host I use in Iowa.

but I will run it at my house for a week or so.

I am 16.6 cents in the winter. and the miner is worthy about 3 cents for the heat so I would pay 13 or 14 cents.

 which is 100 x 13 = 13 bucks to 14 bucks in my house.

for me to see it in house I would need a big runup in price.

My host is cheaper and makes it possible to use it.

[Nexus9090]

Thanks,

That looks like an interesting way to set-up.

I hope they're sufficiently insured for equipment losses etc.

For domestic electric supply is around $0.33/KWh here in the UK and its about to go up again by another 5-10% thanks to the muppets in government and their green climate scam rip off agenda.

Not sure what industrial rates are but a quick look shows they're not that much cheaper. UK energy supply is just a gigantic rip-off

edit gear arrived



So I will update how this resolves.

as of now I am hoping altairtech fixes issue asap or I will be out 0.07946 btc

my thanks to altairtech.io admin did well.

[philipma1957]

Good news ups relocated lost package and it appears to be arriving on time tomorrow.

I will get back to this when it arrives!

My thanks to altairtech.io for breaking ups's balls to find package.


it is cold in nj so I am letting gear warm up in the den before i test it.

interested to see if it does the 270th and 13.5 watts.

that would be close to 17 in earnings and since it is the winter my 16.6 cent power is really 13 cent due to heat savings.

100 x .13 is just about 13 power cost.

so 17-13=4 a day profit. in my house and about 9 a day profit at my host.

[philipma1957]

It is a fucking beast
a monster
unreal.

275 th  which did drop to 270 th

[philipma1957]

meter says 3600 watts.

or 86.4 kwatts a day

I pay 16.6 cents since the heat would be used for the winter. I pay about 13 cents

so 13 x 86.4= 11.23 power cost for me viabtc pays 6.26 cents or 16.90 a day


I net to $5.67 a day in house I would be more like 9 a day at the host.

so I pushed limits a bit 800 day roi at the host

  1350 day roi at home (not accurate summer will fuck those numbers up)

140mm fans so it is quieter

[Nexus9090]

 

Makes my measly 6TH solo set-up look rather insignificant.

But then I cant afford to run it all the time either, so I net around 1.21TH at present and that keeps me on the solar panels not on the incoming bill.

Anyway, good luck with it.

[philipma1957]

moved it to viabtc.

the impressive thing about it is 270 th in a machine slightly bigger than the s19xp

so say 265-272th vs 141th

they pull about 3600 for the 21 and 3100 for the 19

so for 500 watts more i get around 125 extra th.

if I could get a jump in price I may keep it in house. till april.

going to use some firmware? i bet it could be more efficient, 10J/T here we come!

If you have a cold spot to run it.

 it does as low as  12.6 watts a th

it seems to do 273 th not 270 th

and 3425 watts if place is cold that is 12.6

and 3700 watts if place is warm that is  13.6




3692watts ran for 18 hours in garage with door shut

[philipma1957]

a nice little screen on right and blurred sorry about that.

it scrolls

antminer
ip
hashrate

sorry hard to do a good photo
note fans are 140mm



It is about 45f or 7c

I opened garage door to drop temps

watts dropped a lot and fast
3570 watts




last nite with garage door open I got watts down to 3425


still

3425  12.55 watts          yeah you won't get this easy as you need a lot of cooling
3570  13.15 watts          this is pretty easy with a bit of work
3692  13.89 watts          this was easy to do and would likely work all the way until April for me in my home.

Very nice,

Are you PPLNS on VIA BTC, Solo or some other payment options?

pps+        I can't get it to work on nicehash account which does happen at times with new gear.

I am back up to 950th with 4 t21's and 1 s21xp

and I have the L7 which is really whaling

[CochnocherCrypto]

XP's are epic! cool to see them out in the world beyond the Bitmain booth in nashville lol

hey it is a beast


 I just signed onto kano discord.


but here is a screen shot of viabtc and the 1 unit doing just under 268th daily on the pool which is where it counts.

[philipma1957]

This is on its way to the Iowa host.

I will have 4x t21 about 700 th
 and one s21xp.   about 270 th
a grand total of around 950-970th

and 1 L7 about 9.5gh

roughly 16 close to 12000 kwatts a month at ten cents maybe 1200 bill and maybe earn 100: a day or 3000 a month

net of 1800 a month. I need to get to june with no issues and I would be break even.

Of course a big uptick and I am doing well.
