    What is the need of 192GB?

    I often execute calculations on a cluster where I’ll need some 500-1000 GB of ram. But I have 32 GB in my workstation and I never felt I needed more.

    Everything I need to do I can do: I can be having many browser tabs open, several IDEs, compiling and have a game engine open at the same time.

    Only times I fill the ram is when I stress test my software for ram usage, but that is to be expected.

      Machine learning/data science stuff.

      Local LLMs is half of it.

      But that aside, I found myself working with huge files that swapped like crazy on my 32GB of RAM, or were completely infeasible to work with. Janky local experiments I wouldn’t want to run on a cloud instance billed by the minute.

      128GB has been a godsend, but I could completely fill 192GB and still swap some if I had it.

      But I found there are happy side effects to having so much disk cache, too. For instance, game modding/tinkering has sped up immensely over 32GB. So has hashing for transfers, or other scenarios where it’s useful to already have a file cached in RAM.

        Fair, I guess I’d also want some ram if I did not have access to a compute cluster.

        But to be fair, for what I do I don’t really think you can fit that much ram on a consumer motherboard.

        In machine learning I don’t generally find memory to be the bottleneck, as long as the GPU can handle it.

        But sure, opening huge files can be big trouble.

          I can rent cloud stuff, but it’s just not worth it for casual/experimental use.

          Like keeping Deepseek V4 loaded and hitting it rarely, but I want it to be in my control… it’s just easier to do it locally.

          Or experiments I launch like 30 times before it works. I’d waste hours moving all my stuff to a cloud instance, configuring it, tinkering with the experiment to get it to launch; the thing would be idle the vast majority of the time. And yeah, I know I can containerize stuff, but some projects I can’t even test without a sizable memory pool.
