PRE-SHIP AGAIN! SOLD OUT [GROUP BUY 5] 3.15 BTC Bitmain Antminer 180GH 300 Units

[CroverNo01]

Just wondering if anyone has thought about making a private Antminer Pool ?

rewards would be much higher than a current big pool, I have seen many new pools start to make bitcoins every day and thought why not give it a go ?

anyone have the knowledge off a pool creation system ? maybe P2Pool ?

I have managed to get my temps down to 35c on each chip by placing miner outside and making waterproof system then setup link over power over Ethernet.

I have found now uses 30% less power! and mines with only 30HW error in 7 days.

Average air temp outside is min: 1c max:9c

I am happy with results

How could that be? The power draw is surely for computation with a by-product of heat as a result??? 35c is very low and pointless otherwise....

My PSU's were running very hot when I had internal now external they are running so cold and more efficient, I will back up my evidence with proof and show colder temp VS warmer with power consumption.

I was amazed at the difference myself!  When I had these internal chips ran at 47c with fan rpm 1570 currently fan is running 600rpm with almost zero noise

Has anyone every tried running this thing with 2 PSU's?

Has anyone every tried running this thing with 2 PSU's?

Why would you need to do that?  Just curious, cuz that seems like two weak psu's.

Has anyone every tried running this thing with 2 PSU's?

I am
I'm running each blade with an HP DL380 G4 server power supply, which can put out 42amps on the 12v line
I had 4 of the power supplies, soi figured why not
I'm running one run of 12 gauge wire from the power supply to each blade
12 gauge is roughly the same as 3 runs of 16 gauge

I'm a big fan of server power supplies
These babies are designed to be run 24/7 for years

Because I have 2 550W PSU's sitting in my closet doing nothing.

I have heard some people run both PSU's to a power bar and then switch the power bar on so everything fires up at the same time.

Have you had any of these kinds of issues?

I have one ant running on 2 old 450W Corsairs, runs like a charm.

Nope
I just always power on the second blade first, then the first blade that has the control board

I am buying a power distribution panel that can turn on and off individual outlets from a web page,
 and can measure power usage
This way if the antminers ever act up, I can reboot them remotely
And I want to know how much power they are using.
I know server power supplies are usually very efficient, and can run at 90-100% load for a very long time

I think sushi is having trouble setting hosted miners to overclock. Mine (2) have been hashing for a week now with no overclock, missing out on almost .1 btc because of it.

This sucks sushi. Please get it together on your customer service, especially when it comes to hosting. I know I am not the only one being affected. Please others chime in here.

Sushi recently PM'd me that he was having trouble getting miners to overclock, has this been other peoples' experience with this batch of Antminers?

YES!  but your warranty will be void....

Greetings Sushi,

if i order one will you overclock it for me?

No offense intended, but really?  A quality ISP will provide you with an SLA and make retributions for downtime.  A bargain basement price cable/dsl provider obviously won't have any SLA.

Sushi's hosting I am sure has many layers to it, and the risk you took by getting cheap hosting is.... well cheap hosting THIS!  

And some of you want to OC a hosted ANT?  What happens if it locks up?  I wonder what 12V power they provide, as OC success a lot of times is directly related to quality of the incoming power...  (source:  I own 9 ANTs and host them myself...)

I think SgtMoth forgot to mentioned that he received a full refund for a few days of delayed start.  Miner Price + Hosting Fee included.

The next group buy will have Mining Time Guarantee Protection for Physical Delivery and for Hosting, but hosting price will not be as discount as it used to be.

Over Clocking will be an option to select at the time of sign up and it will start as OC Ant, however, Hosting Fee and PSU fee will be slightly higher as OC Ants need Gold Cert PSU with 20% more power consumption and higher personal attention time as it will need a few power cycle every so often.

Regular hashing Ants without the mining guarantee will enjoy the discounted hosting price and hosting will start sooner than UPS Delivery Time to your door!

And discounted price will be available as well, but there will be a fee for me to take all the abuse!!!

[Plissken]

sushi Please start my overclock.

Thanks

[eoakland]

I have nothing but positive things to say about Sushi.  very professional, polite, patient, and extremely helpful....excellent customer service.  Thanks Sushi.  looking forward to receiving my Antminer i recently paid for.

Well, i don't like to whine, but here is my experience that i want to share.
First i ordered two units on 10 dec for 4.25 btc, and i can't receive package because of local ups/customs asking additional docs that i can't obtain, so miners likely to be sended back (or even destroyed!) Sushi stated, that they can be a subject of china high import fees if returned. So now they are like "schrodinger's miners" between russia and china customs and i don't know yet if that 8.5btc would return to me at least partially, not even to say about ROI.
Second, i ordered on 25 dec another 2 miners for 3.15 btc from this GB with hosting option to partially compensate previous fail. Now i think that it was the second fail in a row, as hosting still not started! I already trying to communicate with sushi, and last reply regarding this question was on 7 jan where he asks me to supply pool/worker info (i re-sended the email with that info 3 times already, still no reply and no workers connected to the pool!).
In general, i understand that in the first case he sended units in time and customs issues is out of his responsibility. But it would be good if he at least try to offer some kind of workaround, as all benefits of early shipping is lost with the price of 4.25 btc per unit that is still not received. And current situation with hosting is only makes the things worse.

wow, that's unfortunate.  send him a PM
