能不能跑与跑多快，是两个问题。Whether it runs and how fast it runs are two questions.
显存装不下，就只能换显卡。If it does not fit in VRAM, the only option is a better graphics card.
部分运行器支持把一部分工作放到系统内存或 CPU，但还受总内存、架构支持和速度要求限制。先分别计算权重、缓存与运行时占用，再评估更小规格、量化或卸载方案。Some runtimes support system-memory/CPU offload, subject to total memory, architecture and speed constraints. Budget weights, cache and runtime separately before assessing smaller variants, quantization or offload.
例子与判断Example and interpretation
以下是教学情境，不是本站运行或实测记录。A teaching scenario, not a measured or executed site test.
文件装不进显存时，先看运行器是否支持部分卸载、机器内存是否足够，也可比较更小模型或其他量化档。能启动后仍要检查速度与上下文需求，不能把“启动成功”当作“可用”。If weights exceed VRAM, check runtime offload support and system RAM, or assess a smaller model/quantization. After startup, assess speed and context needs. Starting successfully is not the same as being usable.
