Fixing 'CUDA Out of Memory' and Slow Token Generation in Local AI Tools (Ollama & LM Studio)
Optimize VRAM allocation, quantization levels, and KV cache context length when running local LLMs on NVIDIA RTX GPUs and Apple Silicon unified memory.
Tame multi-gigabyte browser RAM consumption, 'STATUS_ACCESS_VIOLATION' tab crashes, and GPU hardware acceleration glitches in Chromium-based browsers.
Modern Chromium browsers (Google Chrome, Microsoft Edge, Brave) use strict site isolation, launching a separate sandboxed process for every active domain, iframe, and browser extension. While this prevents a crashed tab from taking down the entire browser, poorly coded extensions or GPU shader cache corruption can cause massive memory bloat or STATUS_ACCESS_VIOLATION errors.
While inside Chrome or Edge on Windows, press Shift + Esc (or go to Menu (⋮) → More Tools → Task Manager on macOS). Sort by the Memory footprint column to see which specific extension or tab is leaking RAM.
Navigate to chrome://settings/performance (or edge://settings/system) and set Memory Saver to Maximum so inactive background tabs release their DOM heaps after 15 minutes.
