Yeah, I'm guessing you have a variant that fits in <128GB with 262k context? I have the unsloth Q8 GGUF of it here in a setup that with full context and ton of extra llama-server "--cache-ram" sits around 200GB RAM usage on a 256GB system, it's probably the best thing I've found for a 256GB class machine. Enough headroom for a rope/yarn extension to 524288 context if I need it.

Yep, the engrams are on NVMe (the speed penalty was lower than I expected) and it is quantised to fit.

It’s good enough that I’m considering a second spark, or selling this and buying an M5 Ultra with 256GB for it
