Review of The Rockminer T1 800 gh/s Bitcoin ASIC Miner

Rockminer has been growing fast in the Bitcoin ASIC miner industry and they have recently taken another step forward with their Rockminer T1 miner. This miner starts things off with a new design that steps away from the tube design that many of the Bitcoin ASIC mining manufacturers are starting to use. The new design allows for stacking and ease of use in that you can easily access cables and connections while maintaining a hot and cold isle in large installations, as well as general simple ease of use in smaller installations. The T1 also has a new controller, instead of a Raspberry Pi, it comes with a BE200 Jet Stratum Miner V 5.47 controller. This new controller can run 3 T1 miners. The specs of the T1 are good as well with Rockminer upping the speed again over the R3-Box.

Rockminer T1 Blades

The Rockminer T1 arrived at my door with no bumps or bangs. The shipping gods are paying me back for the BTC Garden that had arrived busted up not too long ago. The T1 is packaged very safely with foam and also included the BE200 Jet Stratum Miner V 5.47 controller and power cord packed safely within as well. The T1’s packaging will make it look larger than it is. The cube shape is compact and well protected by the chassis. You will quickly find that there are 8 PCIe connections on the unit, 2 per blade. Only one needs to be connected per blade for normal operation. If you are going to OC, make sure that you have a beefy power supply and all 8 power connections attached. I used an EVGA 1300 watt Supernova Gold for this review. The BE200 connects to the miner via a three pin connector cable to the blades that are wired in series.  The BE200 can control up to 3 th/s total or 4 x T1s.  As of the time of writing this the cable are only long enough to chain 3 together.  There will be longer cables in the near future. To connect two or more units, you would connect the cable from the bottom in the chain of one unit to the top of the chain on the 2nd unit. There are a set of instructions on Rockminer’s blog to allow for the extra miners. At the time of this writing, I only have the one T1 unit to test with. If I am able to get a 2nd, I will update with a full walk through of the multi-link process. A few key things with the BE200 on setup, the controller uses the default address, and you need to log in using to access it. If your network is setup on as many are, then you will either need to switch it to and change the controller to it and flip back or connect directly to a laptop that you configure to communicate with it. Once you have it on your network, you can then start with the settings. The settings screen is simple and yet has easy overclocking features and a solid, detailed statistics page. The test status page shows you the chips and if they are up or down. This feature can be handy for troubleshooting board issues.

BE200 Settings

The BE200 controller is very picky about pool setups. On mine, I set it up using a tablet. The tablet was adding a “space” at the end of my pool selection that did not cause an issue on other controllers yet stopped this one dead. Dogie also told me that they have a large block limitation that can cause issues with some pools. I was able to get it to work on BTCGuild and yet  had troubles with Eligius. Nasty Pool worked fine, that one is a P2Pool, but the hash rate was cut down to 620 gh/s. For this review, I used BTC Guild. I want to note here that Rockminer’s customer service is amazing. When I had an issue at first with getting the controller to connect to pools, Alex of Rockminer got right on Skype with me and gave me some extra settings to try. I am impressed by that. Rockminer also has a nice detailed setup guide to for troubleshooting as well. Rockminer has impressed me each time with their miners, service and prices. They are determined to grow and bring mining to more people, and it shows with the little touches like that. [divider]CCN[/divider] When running, the T1 is quiet compared to many of the other miners I have reviewed lately. At 4 feet, I read 53 dB from it on normal settings and when clocked to chip Freq 300 it was 59 dB at the same distance. This lower noise makes it a nice unit for in-home mining as long as you have it in another room.

The miner itself has the fans pull the air in over the blades that gives it a nice even cooling rate. The miner stayed cool even in my hot mining room. My best results were on BTCGuild with an average hash rate of 750 gh/s to  793 gh/s over 24 hrs at Freq of 270. The Rockminer T1 is a solid next step for Rockminer. The easy to stack cases with the ability to chain up to three together. The side access for power connections makes it easy to connect your PSU to the unit and standard access point when stacking. With it’s small size, you can fit a lot of them in a small amount of space. The controller being a bit sensitive can make it difficult for new miners but their excellent customer support will help get those who do have trouble up and running quickly. More experienced miners will like the tweaking features and performance. With the Rockminer T1 and BE200 controllers, the usual 10% rejection rate that seems to plague the AM Gen 3 chip has come down to 6% to 7% in my tests. When I first started running the T1, it was hovering at 4% but it did tick up over 24 hrs. Still an improvement which shows me that Rockminer is looking to make improvements for performance that work and that they are getting some positive results doing so. The Rockminer T1 is a solid entrant into the market and a good choice. Rockminer as a company continues to improve and push out easy to use well-performing miners. Disclosure: Miner was provided at a discount and as a pre-production unit for review
