Hello miners!
Currently we are doing stress tests, and we found out that the overclocking sweet spot seems to be between 250-260 GH/s (per card). This is the range that seems to have good stability over the power consumption and temperature, which means 1.1W/GHs and 59°C. The room temperature was 22°C. With this setup, the mining rig would have a hashing speed of about 750-780 GH/s and a power consumption of 825W-900W.
Here is a picture of 2 cards (4 blocks) running at about 130 GH/s each (one mining card holds 2 blocks, and each block has 4 chips):
However please keep in mind that that these are the OVERCLOCKED results. The default nominal hashing speed is 25GH/s per chip.
Here is the setup:
In other news, we will be opening pre-orders for the official products within a week. It will be possible to buy rigs (3x cards, 1x motherboard, 1x power supply and Raspberry Pi) and mining cards. Mining card buyers will get 1 motherboard for free, because it is needed to operate the mining cards. This is intended for more experienced users to build their own rigs and use their own PSUs. Motherboard has 1x ATX-20pin connector and 8x mining card connectors. A Raspberry Pi connector (with our software ready) can be purchased separately to control the device. We have estimated that it takes 2 weeks for the products to ship after we have received payment.
There exists a minimum order quantity for ASICs (from Bitmine) that we purchase, so the minimum amount of rigs for the pre-order to happen is 21 in total, or 63 mining cards. We will also limit the amount of pre-orders to 80 rigs or 240 mining cards to ensure that the production is not encumbered and that the products will ship at the required time.
3 beta rigs will also be up for sale and immediate shipping next week. They are now being assembled in Finland as we speak. The beta rigs can be considered the same as the final product. The beta rigs are sold at a price of $4099. They will be shipped from Finland, so there won’t be import duties inside the EU.
The final prices will be revealed soon, but for now we can tell that the rig’s price will be close to $3700 and the mining card’s close to $1100. We understand that the $/GH/s ratio is not the best around, but as a small manufacturer, it is hard to compete in price with larger manufacturers. We are, however, using quality components and will be shipping products at a steady, reliable pace.
We will soon post again to tell you the latest news! The release of pre-ordering will also be informed through our site’s newsletter.
