This is the third video about my AI inference machine, Larry. I recently installed a Blackwell 6000 Pro 96gb. You should watch to see how well it runs popular LLMs like DeepSeek-V3-0324 Q8_0 and Q4_K_XL, as well as DeepSeek-R1-0528 Q4_K_M, and Qwen3-235B-A22B-128K. I also throw in a crash test of ktransformers and talk about why Ive recently stopped using ktransformers in favor of llama.cpp. Finally, I run a memory bandwidth test of my system using Stream Triad to help understand performance bottlenecks.

Greenworks 80v Chainsaw vs Stihl Farm Boss 290
UPDATE: The chain on the Stihl saw is a semi safety chain after all. I think its an RM3 semi chisel.
UPDATE 2: I think the bar on the Stihl was hot due to the anemic oiler on the MS290. Ive adjusted the oiler screw to wide open. Hopefully that will help in the future.
