Biostar tb 250-btc pro

Other Hardware
1

I am using BIOSTAR TB 250-BTC PRO.
So far, I have made 10 12GPURIG with GTX1070.Everything is working fine.

This time, I tried to configure a 12 GPU RIG using AMD RX5700XT.
However, although it starts up to 10 GPUs, when the 11th is connected, the BIOS is not displayed.

I also changed the connection order and cables.
I tried replacing M / B, CPU, MEM, PSU, GPU, riser card, etc., but the status does not change.

No matter what I do, when I connect the 11th sheet, the screen does not appear, and there is no signal on the monitor.

Is there a BIOS setting for AMD or RX5700XT?

This is my first experience and I am in great trouble. Please give me some good advice.

I look forward to working with you.

Did you ever find a solution to this?

3

No. I haven’t found a solution and I’m running on 10 GPUs.
Do you know any way?

I figured it out yesterday.

-Boot into the motherboard bios
-Go right to Boot settings
-Scroll down to CSM support and set it to DISABLED
-Save and Exit
-Install remaining graphics cards

Thank you for your reply!
Did you recognize 12 GPUs in that setting?
Is it working properly on 12GPU?

6

Yeah. All 12 cards boot and the rig is more stable. I was able to push some of the OC setting higher on the original 10 cards.

Wow! It’s great!
Which GPU are you using?
I am 5700XT.

I have this board in a few different rigs.

1 @ 12 x 5700XT
6 @ 12 x Vega 56 and 64

I also tried it today and succeeded in recognizing 12 GPUs.
Thank you!
