Re: 5.5 - 6.5 TH/S BTC Mining Setup -- need to unload - MOVING!

Yes, I do have the cases and the screws of course. -- the tops are off for cooling purposes.
- These are being marketed locally in the DC area as well, and I have to say I would sell locally first and have someone interested currently.

Where are you located? -- (Houston, TX I presume) --



Do you have the rest of the cases for the C1's?  Looks like the sides are off the units.

I am interested.

Thanks,
MC

   JUSTIFICATION: Ebay is selling S3’s for $260 each ($1040, the low end)
   4 HX1050’s x $150 each = $600
   (NEW is $200 each + $10 shipping = $840)


2 Rocket Boxes (450-480 GH each) w Rasp Pi, USB Hub +1 Corsair HX1050 PSU - $600.00 for everything
      JUSTIFICATION: Ebay is selling these for $420 each (not including Pi or USB hub etc ..)
   1 HX1050’s x $150 each = $150
   (NEW is $200 each + $10 shipping = $210)

      JUSTIFICATION: Ebay selling for $60 each plus $12 shipping. 


Please let me know if you are interested — I can deliver TUES - THURS from 10am - 1pm. OR in the evening.

I prefer BTC payment (at current daily rates)  - but cash always works too .


I will be putting these all on Ebay in 2 days if they are not sold … so get it now if you want it —

Thank you!

Here is my breakdown of everything — and I think it’s a very fair asking price — Delivered in DC AREA.

It includes 10 Overclocked Bitmain S1's running at a bit over 200 GH Each + 3 EVGA 1300 G2 PSUs =  $950.00

   10 x $50 each === $500.00  (Avg Ebay is $60 each ($600), not including delta fans or over clocking)
   3 EVGA x $150 each = $450   
      (NEW is $200 each + $10 shipping = $630)

2 overclocked S2’s each with upgraded EVGA 1300 G2 PSUs -  $1100.00
   
   $450 each on Ebay, without upgraded EVGA PSU
   2 EVGA x $150 each = $300
       (NEW is $200 each + $10 shipping = $420)

4 overclocked S3’s @ 450-480GH each + 1 Corsair HX1050 PSU each (4 PSUs total). -  $ 1600.00
   
   Ebay is selling S3’s for $260 each ($1040, the low end)
   4 HX1050’s x $150 each = $600
   (NEW is $200 each + $10 shipping = $840)

2 Rocket Boxes (450-480 GH each) w Rasp Pi, USB Hub +1 Corsair HX1050 PSU - $950.00
   
   Ebay is selling these for $420 each (not including Pi or USB hub etc ..)
   1 HX1050’s x $150 each = $150
   (NEW is $200 each + $10 shipping = $210)


ALSO INCLUDED:
5 shelves for setup - although you may need another shelf. - Free add-on
2 Enermax REVOLUTION87+ 1000W — PSU - free add-on ($200 each new) (came from the S2’s) —
1 Free S1 - performing at 150GH avg.

Everything listed Bought NEW/ONLINE — without the free add-ons (shelves, enermax PSU, free S1) — $5,460.00


ASKING PRICE: $4,200.00 or 10.50 BTC (Price break for paying BTC)





I'll start it off - 4 BTC and I'll cover shipping.  No shelves needed.  The ant s1's will end up being undervolted and require a mess of cables.  I've never gotten a rocketbox to work very well - so other than being paper weights, I'm not very aware of their value.

Re: Antminer S2 -- just crapped out on me -- help -

Do you have a specific suggestion for brand / type of PSU to replace what is in it currently? -- I've looked around and I can't find a PSU with two 12 pin connectors. -- the standard is 10.   Please specify.  THank you!!



if the miner starts up and shuts down, it is almost certainly bad PSU. You do not need to wait for it to cool down for more than 5 min. Just take out the power cord, take out and reinsert the jumper, and you can start the system again.
The easiest check is to remove one or two blades, and if it works at 80-90%, then grab a more powerful PSU and you will be fine. They did a very bad job putting in 1000W PSU when the system requires over 900W.

Antminer S2 -- just crapped out on me -- help -
by
gauston
on 25/07/2014, 18:11:54 UTC

Hi all -

I have 2 S2's -- purchased just 2 weeks apart - back in early June .
The first ordered S2 antminer (order # 00120140617210324211R5oX3cPM0667)  has suddenly stopped working -- it will turn on, but then turn off after about 5 minutes.

I have opened it up, disconnected the PSU - let cool off for 3 days then tried again. - turns on for 5 minutes then completed turns off, no power at all.  The 10 blades don't even turn on (no blue light on chip boards) during the initial 5 minutes. -- So, I think I might need a new PSU but then again it could be the mother board. - or is it just a simple PSU issue?

BITMAIN has been contacted THREE TIMES and has NOT gotten back to me -- I'm out almost $1800.00 here ---

Has anyone has any luck with other PSU's? -- if so which ones? - and I noticed there are 2 PCI-E connectors and 2 twelve pin connectors (NOT The standard 10). These last two connectors are the hard ones to fit. 

Any advice would be appreciated -- thank you --

Hey there!

I would like to know if you guys think that this is not a scamm:

http://sushi-review.com/products/bitmain-antminer-s1-180gh-s-miner.html

Thanks  for the help mates!


HI - Not a scam BUT - if you are hosting yourself you will need to purchase a power supply - which will cost $300-400. Personally - to me that price seems of 1.5 BTC - SEEMS VERY LOW -- I just purchased FOUR for those machines for $2k each, without power supply.  You can overclock them to 200GH which I would recommend - they work fine.  Oh, You can fit only 2 of these of ONE power supply .. Just FYI -- My only advice is to ask how they can possibly sell them at that price, too low in my opinion by about $500.

Re: Please help - Hashing getting hijacked!
by

on 09/02/2014, 00:55:17 UTC
There are several possible causes for this, including:
- You have a keylogger on the system that you use to configure the miner. Every time you change the password, it's captured by the keylogger and sent to the attacker.
- The OS on the RPi has a security vulnerability that can be exploited.

You should first figure out how the attacker is gaining access. If it's through a keylogger on your system, then just slapping a firewall in front of the miner isn't going to do anything.

The biggest problem is if you have been using a standard password in the beginning as had the machine accessible globally via internet.
You will have to reset to factory settings as most probably you have malware on it.

--- I SHOULD MENTION - The Raspberry Pi device is attached to the ethernet cable straight from the cabinet -- there is no router / firewall currently. Just a static IP on one line ...
Basically - I'm looking for advice on how to set up a firewall device -- what Exactly to purchase and how to configure it.. Seriously - any suggestions or advice is welcome.

As to the other poster - I do not have any keyboard or monitor hooked up to the miner or raspberry pi -- I bring a monitor and keyboard when I go to the NOC (Hosting facility) --


Hi - The ORIGINAL SD Card with MinePeon installed did have the default password.  Once I was hacked (the first time) - I switched out an ENTIRELY NEW SD Card with MinePeon reinstalled -- with a VERY secure password (25 char+) --  The Hacker is back -- and seems to have broken that one too.

The Butterfly miner that I purchased originally came with an android tablet interface - but the seller replaced that with this Raspberry Pi device because it works better. And it does, and I truly trust the seller - he has bent over backwards to get me up and mining --- as well as advice and an education.  I truly do not believe it is him.

Thank you!

Hey All -

I'm obviously new to Bitcoin mining --- after researching I went in big -- and purchased a 500GH machine that runs via a Raspberry Pi device running MinePeon.  And it works great. However - after a few days I noticed that a new pool had been added and it was stealing ALL of my hashing - i.e. my money.

I kick him off, change the password and he comes back to add his pool about once per hour.  He's get on for about 10-15 minutes before I notice. So he's getting a nice chunk of my hashing time.

The machine is hosted at a local facility but The machine is NOT behind any firewalls -- and this is where I need your help and suggestions --
I have never set up a firewall before so absolutely any information or insight would be greatly appreciated.

What do you think of this firewall - I'm thinking of purchasing it.:

Thank you all in advance -
