Not to spread anti-environmentalism, but an obvious great market for this is people who have unmetered water. Wink

Winter is coming... I want to see someone use this as a hottub heater.

40C bath wouldn't be that fun Tongue

102-104F is perfect hot tub temp!

Re: Help identifying a miner

Picked a miner up that was advertised as a 200GH SHA256.

Trying to identify what it is. Has a rPi in it as well.

Anyone know?

Thanks in advance.

It's a 2nd Gen Avalon1. NOT an Avalon 2. I had one.

Essentially it is the same as an avalon 1 but uses 55nm chips instead of 110nm.

*Avalon 2 clone.

The controller board and PDU inside this unit will say Avalon 1.5

Shipping to USA is WRONG ... Grin

You DID NOT Select UPS...in shipping methods...I WISH your numbers are correct... Wink

0.21 BTC for C1 ...

0.358 BTC for S3+

Cheers,

Good catch. Haha. Doesn't change the outcome much

Why would anyone buy this? It is essentially 2 S3+'s crammed into 1 case with the added hassle of liquid cooling.

1x C1: 1 BTC + $50 in cooling parts + hassle of water cooling
2x S3+: 1.07 BTC   <-- Still the winner

Well at least you save some shipment charges......

2x S3+:
1.07 BTC
0.087 Shipping to US
= 1.157 Total

1x C1:
1.0 BTC
0.048 Shipping to US
0.13 (Cooling equipment $50 @ $377/BTC)
= 1.178

It doesn't save that much space since you still need room for the cooler.
It's not any quieter since the radiator will still have fans.
It's not any more efficient since it is using the same hashing boards.

I don't get it. I guess some people just have a hard on for liquid cooling. Huh

I did notice the lack of pictures of small miners in this thread, it means that mining is really turning to be a corporate professional task since the introduce of ASICs.

It's not that it is "corporate", it's just not interesting to post a small setup. Nobody cares that you have 2 S1s hooked up to a 750W psu. The days of rat nests, daisy chained motherboards with 20 pci risers and custom GPU mounts made out of chopsticks and bubblegum are in the past when it comes to bitcoin mining.

Hi,

one of my S3 miners has an extreme low hashrate (80 GH/s).

It seems that it is not pulling the frequency data from the config file.

I've attached a picture, looking at the config file it shows that the frequency is supposed to be the standard 218.75.

Factory reset didn't help.

Anyone knows what to do about this?


You need to go to the miner configuration tab. Select advanced and choose a frequency. Save and apply. all better.

Do you really need to know the whole story? Ok well listen. When I started out mining my electric rates were $0.19 per kw. After I added the Terraminers in March my electric usage went up considerably and every month my electric company threatened to raise my rates. Well they finally did it last month. They raised it to $0.34 kw. Happy now?

Yeah, actually. I wasn't trying to attack you. It just seemed strange to declare a piece of hardware unprofitable when it is really only a unique (and very shitty) situation that caused it to no longer be viable. Sorry to hear about your power company. Hopefully you can find some co-location or sell it to someone in an area where power is more affordable.

How can you come on here and tell me to check my math? Do you know where I'm located and how much I pay for electricity? I didn't think so.

Ok... so what are you paying for electricity?

Mining is barely profitable for me here in the states paying $0.17 per kwh. If you are paying more than that for power IDK why you'd even attempt to mine. Unless you are paying more than $0.32 you are still breaking even. Factor in speculation that the $/BTC increases, the TerraMiner is still profitable for now.

Here's what I did with my setup. It's a little different situation because I have a 200A main breaker box with plenty of room.

Here is the new 60A 220V breaker added to my main box with a 6awg 3 conductor wire leading to my sub panel:
http://i.imgur.com/uxO8y4C.jpg?2

Here is my sub panel. I decided to go with 15A 110V breakers with a single breaker per 1000-1300W power supply. I used 14 awg nema13 power cords and cut them off to wire them directly to the breakers, thus saving money on recepticals, outlets, boxes, condutit, etc. I checked with a couple power guys and everything seems to still meet code.

http://i.imgur.com/qflcK84.jpg?2

Here is the box all covered up. The big 'breaker' with the white label is actually a whole home surge protector. I didn't want to waste my money on PDUs or individual surge protectors so this was a good solution for everything on the sub box.

Here's the whole cabinet. Obviously this is a little easier to do in a cage but could pretty easily be mounted on a wall next to your shelf-type setup.

Well, the day has come where it costs more money to run my Terraminer than it makes. Time to shut her down.  Sad
Its been fun. GL all.

I think you need to check you math.
1.6Ths @ Diff of 23B is still 0.034BTC per day, about $16.50
2200W costs $9.00 per dat at 0.17 $/kwh.

You're still making $7.50 a day.

A 7 Th/s setup in my garage.
3 Antminer S2s
1 TerraMinerIV (with half it's guts removed)
6 Antminer S3s

I just finished putting everything together this weekend after dealing with months of running a disorganized overheating rat nest of wires. Moving to a rack is SOOOO much easier to keep things cool and orderly. The biggest challenge was power. I took the idea of using mini-breakers that was discussed in this thread a couple weeks ago and decided to use a standard breaker box instead of multiple PDUs or MCBs. Now I have plenty or room and power to expand.

Hi all, been spending some time reading through this thread trying to see if anyone has a similar issue, and whilst I think people do, there doesn't seem to be a fix.

It all started with the top PSU showing an orange light on the right and green on the left, unit not mining at all.  When you turned on just the top one the fans weren't starting on the unit. 

The customer service at Cointerra is shocking (and rude), the issue was reported mere days after the 3 month warranty period, I'm in the UK so I'm sure it will cost more than the $350 non refundable fee to get it there (they won't even allow me to ship and return - they make a FORTUNE on their shipping rates I can tell you shipping myself on a corporate UPS account).  The breaking point was even if you do that, a 7 day warranty period on the repair; really?!  So I'm voting with my feet, I won't be buying anything else from them again and being an advisor to many BTC onboarders I'll ensure they don't get anymore new custom, in my mind they're not far off Butterfly labs now.  All that said, decided to self diagnose and try to fix.

The problem...

1) When opened main board had no lights (the night rider orange ones on the board).  Not even at startup and no fans.
2) Switched PSU's and ruled out that problem as the good PSU then became the bad.
3) Checked all connectors
4) Tried removing the black and white cables from the faulty board - nothing.
5) Swapped out the 2 boards checking all connections along the way.  No leaks found, no bad connections.
6) After swapping boards around we've worked out a board is at fault and as it was the primary board there was no mining.  Now the machine is mining on one board so that is an improvement.  Interestingly both PSU's need to be on or the unit won't stay online.  If you don't power up or power down the 2nd it goes offline (can't access over LAN etc)
7) Now the original problem of the orange light on the PSU is on the bottom one.
Cool No lights on the faulty board at all, not even on startup.
9) Looking at the nightrider lights on the working board D42 and D45 don't light in sequence (on startup D42 does but not D45) so I assume this is why it's hashing at around 700. 
10) Only CTA0 displays on the admin screens (before we started I couldn't get to this menu as the faulty board was the main one).  On the front of the machine it blinks on Miner 2 as mining.
11) We've not amended or touched the coolant system yet, there appear to be no leaks.
12) We've tried resetting the boards, we've tried resetting the system etc.  Firmware is 0.7.6, I tried to install 0.6.32 but it loads but doesn't downgrade.

So.. a board seemingly without power, PSU's seemingly fine, cooling seemingly fine, everything follows the board.  Have meticulously checked the board and can't see anything obvious.  Any ideas?

Would really appreciate any advice, thanks all.

David

I had a similar issue with my TerraMiner. One of the boards shorted out, resulting in an orange light on the PSU. I could not find a fix for the failed board, so i removed it, its cooling, psu and psu breakout board. To point 6, You CAN run the system with just 1 psu in, you just need to make sure that the small beaglebone power connector is attached to the single remaining power supply. In one of my previous posts in this thread i outline the reapplication of diamond thermal paste, this is a good step to take on your remaining board to get your miner running stable at 1/2 speed. Sorry about your dead board Sad

Okay thanks JoseSan... I'll give it a try. It appears though my woes with Cointerra are more serious than beaglebone. Both of the hashing boards are over heating badly. I saw a reference to some videos on how to repair the cointerra boards by reapplying thermal paste. I looked for the videos but could not find them on Youtube. Can someone please post the link for the videos. It looks like I am going to have to perform a full repair on this piece of crap hardware. Ugh!


Hey mmfiore,

I've done the thermal paste reapplication. its pretty easy.

1. completely remove the processor block/radiator assemblies from the system. You will need to disconnect the power wires from the boards as well since they weave between the hoses.
2. Completely remove all the old thermal paste and clean the the blocks and processors using 90%+ isotrophyl alcohol and q-tips.
3. Apply thermal compound only to each processor, not the pump blocks. About the size of a BB on each core. I prefer "Innovative Cooling Diamond 24 Carat". It will get you results similar to the "Liquid Pro" many others are using but doesn't have the shorting risks of conductive paste.
4. line up the block above the processor and get the mounting screws started. Do not apply downward pressure on the block until all 4 screws are started.
5. Apply firm pressure straight down on the block and tighten all the mounting screws.

Done.
