History’s BEST in Cryptocurrency Mining: BIOSTAR TB250-BTC PRO 12 VGA Set Up

First Timer wanting to find out more? An old-timer in the field wanting to know about the new board? We’ve got information just for you!


Following in line with the popularity of cryptocurrency mining, mining is no longer only something that a computer geek will do and has slowly crept into the houses of everyday users. As such cryptocurrencies become increasingly more valuable despite some fluctuations in the valuations in the beginning of the year, these currencies tend to bounce back quickly, coupled with a fast ROI, there is little wonder as to what’s drawing so many people to join this every growing community.

Most of the mining rigs that are currently in use tend to be those fitting 6 mid-high range graphic cards. However, we at BIOSTAR has decided to one-up on that to push out our latest model that can fit a whopping 12 graphic cards to up YOUR mining game – the BIOSTAR TB250-BTC PRO. Now with a board that can fit up to 12 cards, there should be so many questions popping up for all our mining enthusiasts, such as the setup, stability and power draw.

Read on, coz we’re here to answer all of your questions!



Let’s start by having a good look at this board, shall we? This board utilises the B250 chipset, but the left of the board gives us ample room for 11 PCI-E 3.0 X1 slots and 1 PCI-E 3.0 X16 slot, totalling up to 12 slots. Hence, you should also look for a good extension adapter.




With 12 cards slotted onto a single board, we’ll need a dual power supply, and we suggest that you go with the same brand and the same model for both power supplies, since using different ones will require a different setup. Furthermore, with different currents flowing from both supplies, if an incompatible pair was selected, it might result in damage to the board, the VGAs or the power supply.


Connecting the power as below, ensuring that the power is always connected and flowing smoothly to provide power for the graphic cards.



Although regular boards with 6 cards for mining only requires 4-8GB of memory, this board will require a 16GB memory in order to maintain 12 cards mining at the same time, or you might have the rig stop function properly.


Moving onto the cards, it doesn’t matter if you’re going with AMD (A) or NVidia (N) since the rig will only support up to 8 cards from each manufacturer. This means that for a 12-card rig you can go with any of these combinations: 6A+6N, 8A+4N/4A+8N, 7A+5N/5A+7N. Naturally, if you expand the PCI-E slots, you can always run the 8A+8N combo.


In this case, we’re running a 6A+6N combo, and from experience, we suggest that you first start with connecting the AMD cards. Below, we will start with the system set up for the AMD cards first.



With the hardware set up done, now we’re moving onto the BIOS set up. First, boot the system up and enter the BIOS setup. First, head to the Chipset interface to select the Mining Mode option and select the Above 6x VGA (UEFI).


Now, head to the BOOT interface, and set Video to UEFI and hit F10 to save.


Entering the BIOS again, head to the Boot interface to disable the CSM Support, and hit F10 to save.


After setting up the BIOS and hardware of the AMD cards, it’s time to connect the NVidia cards and booting up the system.


The Completed Setup:



NVidia Card Software

Starting with the NVidia cards, we can use the星火Zcash Mining Software ver 0.3.3 or the ZEC Mining NVidia ver 1.1, which is both easy to use.


All the settings are just to modify the storage settings, and we usually use the C and D disks.


Just copy the address to the wallet field and we’re good to start mining.

AMD Card Software

For AMD cards we will be using 星火Claymore Zcash AMD Card Mining Software ver 12.0.

Entering to the correct folder, right click on双击挖矿.Bat and press E.


Now you’ll need to configure your wallet and the blue selection below is the wallet that you need to configure. After configuration, you can close the application and double click to start the mining process.


Finishing the steps above will allow us to start mining with 2 different applications to mine simultaneously.

MINING Process

Mining for the same ZEC Currency below shows you the prowess of mining using 6 RX580 + 6 GTX1060 running simultaneously.


Below is another screen capture of the 24-hour monitoring of the mining process.


In 24 hours, we have mined a total of 0.08 of the currency.


This rig uses a total of 1961.5 watts, which equates to 1.96 DC/hour.



As you can see, the calculation process calculates this 1 rig as 2 separate machines and the average calculations are 1.7KH/s and 1.6KH/s, and hence has a total rate of 3.3KH/s, and is obviously doubly faster compared to those with only 6 card slots.




By using the BIOSTAR TB250-BTC PRO, 1 board can fit you 12 cards and helps YOU save on a CPU, a motherboard, a hard disk, which can be quite a significant sum when you’re just starting out. At the same time, this board allows you for mining at TWICE the speed. So if you ask me, which board is best suited for mining? Without a doubt, I’d say it’s this board.


We hope you guys enjoyed this latest blog post and stay tuned for more. Until then, peace out!
