Update on the “Monstrosity”. 6 BC-250 board cluster

post image

This is 6 bc-250 ex mining boards with 5 in the asrock 4u12g case they came in. After a lot of testing my current preferred setup is 4 boards running Qwen Next Flash IQ2\_XS at 100k context with around 28 tok/s for short generation and 24 tok/s at 50k with around 115 ppt. The other two boards run 3.6 35b q4 at 60 tok/s with 100k context and 450 ppt. This is all using llama with vulkan and rpc over 1gb Ethernet.If anyone has any suggestions with this beast I am all ears. I had these boards left after reselling a bunch and had never done anything with local ai before so this has been a blast. Also yes that is a cardboard box with 3 fans on top as the intake.
