[SOLVED] Biostar TB250-BTC Pro not detecting a GPU

[tjim16]

Hello,

I just built a mining rig with the following specs:

- Biostar TB250-BTC Pro
-EVGA 1000w PSU

• 3 RTX 3070 (8GB)
• 1 1660ti (8GB)
• Intel Celeron G3930
• Kingston SSD
• Crucial RAM 8GB DDR4

I am currently able to mine with the 3 RTX 3070's no problem, but the motherboard isn't recognizing the 1660ti when I try to run it with the other three cards. The 1660ti fans are spinning and the GPU riser LED's are working which indicates it is receiving power. I have the most recent drivers installed for the cards.

I tested the 1660ti on my other PC which has an Asus X-570 motherboard and I was able to mine with no issues and motherboard recognized the card. I am having a hard time deciding whether this is a Biostar motherboard issue or not. I have the most recent BIOS version installed and have tried connecting the 1660ti in each PCIE slot with no success.

Has anyone had any issues with this? Thanks.

You won’t find much help with mining here.

I would sell all of the GPUs and use the money to buy Bitcoin/ETH. With GPU prices the way they are you will easily get about $2,000 worth of Bitcoin/ETH. This is way more than you would ever be able to mine yourself on four GPUs
