Hi Miners! It's been a long time since our last hardware spotlight article. The hardware we are reviewing this time is an FPGA mining board that has been around for a long time in FPGA crypto mining community. It's the CVP-13-L by BittWare! Without further ado, let's get started!


CVP-13-L is an FPGA mining board produced by BittWare. CVP-13-L is one of the most powerful FPGA board available. It's using VU13P chip which is a huge FPGA chip with 1,728,000 LUTs. However, with great power comes a great price tag 😅, alas, the CVP-13-L is priced at $5,495‌.

Mining and Profitability

Currently, CVP-13-L can mine 17 different algorithms. Nine developers are working on this board: Zetheron Technology🔥, Penfold, Dr Merxius, GPUHoarder, Protovist, Senseless, Nez, Crypt, and Dedmaroz🎅🏻.

The most exciting one is X16R by Zetheron. Zetheron has released the first version of X16R, but it's still unprofitable since it's still an uncompleted version.

Check out the complete list of algorithms on the table below:

Algorithm Coins Developer Hashrate
X16R Raven, Bitcash Zetheron🔥 220 MH/s
0xToken 0xBitcoin Zetheron🔥 24 GH/s
Nexushash Nexus Zetheron🔥 2.3 GH/s

CVP-13-L also comes with a handy tool called Bittworks II Toolkit LITE. You can monitor your FPGA status and change the core voltage using the Bittworks II Toolkit LITE. You'll get this tool for free if you purchase CVP-13-L. This tool is available for Linux and Windows (Lite version). You can get it from the respective retailer you bought the CVP-13-L from.

We also did some tests on the CVP-13 by ourselves. Here are some test results:

Vblake 0xToken Nexus
Hashrate 7.8-8.3 GH/s 22-23 GH/s 2.2 GH/s
Power 359 W 367 W 398 W
Temperature 55oC 44oC 50oC
Revenue $2.32/day* $2.84/day** $2.38/day**

* based on online profit calculator per Sep 12, 2019
** based on online profit calculator per Sep 23, 2019

The testing result is similar to the claimed hashrate. Some people in the FPGA Discord Community has also reported a similar hashrate.

We also did some testing with Zetheron's X16R. \We got the Zetheron's X16R working on our CVP-13!

  • 🐘 Powerful VU13P Chip. VU13P is 46% bigger than VU9P. It's able to fit more cores into the chip, which means it can produce more hashes than BCU1525, BTU9P, and other VU9P boards.
  • 👨‍💻 Developers Working on CVP-13. A lot of renowned developers like Whitefire, Dedmaroz, and Allmine are working to make bitstreams for this board. There's an upcoming X16 algorithm for CVP-13 coming soon!
  • 💧 Built-in Waterblock. CVP-13 is ready to be water-cooled.
  • 🛠 Tools for Monitoring. You can use Bittworks II Toolkit LITE to configure voltage and monitor the CVP-13. This tool is convenient for monitoring and controlling the CVP-13.
  • 🤝 Trusted Manufacturer. BittWare has been around for over than 25 years.


  • 🔬 Unoptimized Bitstream. Some of the available bitstream for CVP-13-L is unoptimized, so the device hasn't reached its maximum potential yet.
  • 💸 Long ROI Time. As mentioned before, some of the available bitstreams are not at the maximum hardware potential. Resulting in a long ROI time for this device.
  • ↔️ USB Connection Issue. Some CVP-13-L users experienced some issue with the USB connection. Error rates are higher than expected because the USB serial buffer of CVP-13-L is smaller than VU9P boards. Future bitstream builds are supposed to fix this issue, or you can use a shorter and better quality USB cable.
