I rebuilt my PII system last year and really wanted to run SAH on it for old time's sake but sadly that hasn't been possible for a long time. I miss watching that old screensaver and optimising the system performance so I could get through a WU in less time, iirc at the time it took about 18 hours each.
I recently picked up a Threadripper 3960x, 256GB DDR4 and RTX2080ti 11GB running Debian 13 and open web-ui w/ ollama.
It runs well, not much difference to Claude etc but still learning the ropes and how to get the best out of it and local llms in general. Having tonnes of memory is nice for switching out models in ollama quickly since everything stays in cache.
The GPU memory is the weak point though so I'm mostly using models up to 18b parameters that can fit in the vram.
