Tuning a Hashbuster Nano

The bitcointalk.org forum is great and contains lots of info about the bitcoin, market, software, hardware, and so on. It’s a worldwide community and most people are sharing lots of info and help people who have some problems or questions.

Recently I bought 10 Hashbuster Nanos and today I took 1 board away  from my tower and started to experiment with it. Try to get it hashing at a higher rate. Standard hashrate is bewteen 2.5 and 2.7 Gh/s. On the board you can play with the voltage which feeds the ASIC chip. Higher voltage means higher hashrate but also more heat! So (extra) cooling is essential. Bitcointalkmember XBOCT posted some very useful tips and tricks.

I did several tests with the board:

  1. 0.981 V -> hashrate: 2.5 – 2.6 Gh/s = stock / unmodified
  2. 1.025 V -> hashrate: 2.6 – 2.7 Gh/s = test run #1
  3. 1.050 V -> hashrate: 2.7 – 2.9 Gh/s = test run #2
  4. 1.124 V -> hashrate: 2.9 – 3.07 Gh/s = test run #3 going nuts

What the maximum voltage is for the ASIC-chip I don’t know, I have to find out later. Have the guts to nuts and just do some crazy experiments 🙂 Continue reading

Hashbuster Nano 10pcs Tower

I already had 3 Hashbuster Nano devices and ordered recently 7 more. Today I received the package and started building. Stacked 10 boards with pcb spacers. Then I contected 9 pieces of electric wire from each 12V + connector to the next and the same for ground connectors. At the first board I connected a (female) molexplug. With some tiwraps I attached three 10cm fans for cooling. Connected the molexplug to the powersupply of my Linux Radioserver and 10x USB kabel to an Anker 10 port hub. Started a modified version of cgminer (3.5.1) and it started hashing right away ! a cool 28Gh/s. For the future I will try to tune it a little to get maximum performance.

HashBuster Nano review

I wrote this review on september 13 and posted it on bitcointalk.org . I also post it here on my blog , in the review I use my nickname WTTBS which I have on bitcoinstalk.org. Some minor type-o have been corrected. You can also download the review as PDF.

Specs (September 13 – 2013):

HashBuster team is glad to announce HashBuster ASIC miners available for immediate order and delivery.

HashBuster Nano miner based on one bitfury chip.

  • 2.5+ Ghash/s speed. In most situations (no overheating and good power supply)
    it produce 2.5-2.9 Ghash/s. Continue reading

Hashbusters Nano run on CGminer 3.5.1

Yes ! thanks to Gades and XBOCT on bitcointalk.org I succesfuly compiled a modified versoin of CGMiner 3.5.1 which works with the Hashbusters Nano ! No need for the Virtualboxmachine anymore.
More details soon. Click here for a manual.

For now a screenshot:

3x Hashbuster Nano on CGMiner 3.5.1

3x Hashbuster Nano on CGMiner 3.5.1

After running for 15 minutes I see that the boards are running at a higher hashrate than before. In the Virtualboxmachine the run @ 2.5GH/s now with the new cgminer they run @ 2.7 to 2.9 GH/s. How cool is that ?!
