Run alone, it reads them hitting 3.3GHz sometimes. I use Vulkan because ROCm seems intermittently unstable. I'm running one agent on each card, mostly Qwen3-vl-30b-a3b Q5 quants (decent performance:context window trade-off), Devstral2-24b, Qwen3-coder, and sometimes Nemotron for simple tasks, but Nemotron has been unimpressive and prone to error during heavy tool use.

I guess my bifurcated motherboard lacks P2P, so loading a big 52GB Qwen-Next-32B model across both GPUs works and gets like \~28 tok/s from zero-shot, but there is still a bottleneck with it juggling read-write across the motherboard.

The limitation forced me to run separate quantized agents, which has been better for productivity and I prefer HITL. (I launch 2x LM Studio instances as a fish function, w/separate APIs and shared qdrant+Neo4j+postgres+memory servers via MCP for long-memory coordination in projects. This allows me to have an orchestration model on GPU0 write and execute python scripts that are queued on GPU1's API. (This coordinated governance structure also aligns with the new [Atlas method](https://www.youtube.com/watch?v=tez4AyTm1Rs) of Agent Orchestration.)

I just wanted to share my experience since I know these cards are new'ish.

I hope everyone had a great day!
