Greetings!

I am just getting back in BTC and picked up two Terraminer IV units for $300 each. I really had no intention of starting mining again but the price was right and having Th/s just sounded cool. I managed to get the latest firmware, manuals, etc from the site, despite them taking it offline (thanks Google cache). I have not been able to find much recently on these and what I have found has not been too positive. I would have a different perspective had I purchased at retail when they came out but after seeing these I am impressed. Granted I only have old 60-110Ghs BFL hardware to compare but these seem solid. As soon as I got them I cracked the seals, cleaned them out and started to inventory the components. One was perfect and the other had a core that was not working. I was able to track that pretty easily to a pump that was not running and after a few minutes of highly technical, very sensitive, work with a specialized tool (removed pump and smacked it with the back of a screwdriver) it was once again pumping and all cores running. So I am currently hashing on Slush's pool and getting 3.2-3.6 Th/s between the two after 24 hours straight and overall I am pretty impressed with these units.

Does anyone have any experience or wisdom with these that you would care to share? How about pools? I used Slush's in the past, and I like the new beta site, but the luck has been bad since I joined the pool. Hopefully I don't have a curse on my miners.

TIA

Hello,

I was wondering if you could upload the manual somewhere so I could download it? I have a Terraminer IV I would like to have the manual. I am mining at BTC guild ATM, it's ok my luck hasn't been that great either.

Thanks!

The Cointerra units do run well so long as you keep them cooled on the different stepping settings. I had 1 of them and could only hash it around 1.4TH each due to over heating (stepping 5 iirc).
You should check out the cgminer dev's pool: https://kano.is/index.php their thread here is: https://bitcointalk.org/index.php?topic=789369.0

You can still grab it from the site with a direct link.

What firmware version are you running? 7.56 was the last version released, AFAIK. I grabbed everything from the website before they went under so I do have copies of everything. Let me know if you need anything.

Actually, I also have a 0.7.6 firmware version, which was released 03/24/14 but the latest is 0.7.56 which was released on 09/04/14 and is the last.

I have the following versions:

0.6.32
0.6.48
0.7.56
0.7.6

I also have all of the PDF documentation from their website. The text below is from the firmware download page.

9/24/15:   CoinTerra is aware of the “Shell Shock” exploit in bash implementations lower than version 3.2.52(1)-release however our embedded firmware is not vulnerable because we are not running bash.

Greetings: one will have the firmware version 0.7.6 thanks

Does anyone have the latest Cointerra firmware they would be willing to email me?  I just got a Cointerra miner but it doesn't have any firmware.

Unless you have FREE power, those things are so inefficient by current standards that ANY price would be "wrong".

 I ran on Slush's pool for a while when I was bitcoin mining, didn't have any issues with it and they have a good reputation.
