Wanted to compare notes with people doing similar things.
My current setup is LM Studio with dual 3090, and I keep running into HBM constraints.
Not looking for the perfect answer, mostly what worked in real use.

I'd approach it in a boring order. Start by verifying the driver/runtime combo, then test with a smaller prompt, then look at workstation thermals. Not glamorous advice, but repeatable baselines save a lot of time.

Did a small comparison this afternoon. The issue went away once I changed one setting and restarted the stack cleanly.

Need a little more detail here. Is this local-only or are you routing anything externally? Turns out 'just one more test' was a lie.

A couple things I'd check first. On 5090, the easiest win is often to back off the aggressive settings and see whether the problem survives. A lot of these threads end up being one bad config plus a pile of conclusions drawn from it.
There are a few different conversations hiding inside this thread, so being explicit about the goal helps.
throughput matters, but tail latency matters too

Interesting, I hadn't tried that. I don't think your conclusion is far off. The biggest change for me was simplifying the stack instead of adding one more optimization layer. The logs were somehow calmer than I was.
