Blender render crashes that are not just VRAM

The problem

The render starts, then Blender closes, the GPU falls off the bus, or the frame stays on 0% until the OS kills it. Buying a 24 GB card does not fix a missing packed image or a Windows TDR timeout.

Cause

• VRAM overflow: CUDA illegal address / out of memory. The scene does not fit. See VRAM limits.
• Driver timeout: a single kernel runs so long the OS resets the GPU. Common on long tiles with a desktop session attached.
• Unstable driver or mixed CUDA/OptiX backends after a driver upgrade.
• Missing linked libraries, unpacked textures, or relative paths that work on one machine only.
• Running out of system RAM while the GPU is fine, especially with denoise + compositing.

Practical fixes

• Read the exact system console line. “Out of memory” and “timed out” are different jobs.
• File → External Data → Pack Resources, then retry a one-frame render.
• Lower subdivision, texture size, and hair for a fit test before changing hardware.
• If it finishes slowly instead of dying, use the time calculator and slow Cycles notes.
• Do not treat a verified benchmark PASS as proof your production file will survive. BenchMork uses a frozen scene.

Estimate local render time

Local total time = frames × time per frame. The calculator also shows a human-readable duration, an independent-machine illustration, and an optional target completion. It never multiplies frames by a public dollar rate. FARPY price comes from a live quote after upload.

When inspect still matters

FARPY inspects the uploaded .blend and returns a locked quote before start. Inspect tells you whether the file is accepted. It is not a promise that an over-limit or broken-asset scene will finish. Failed work is not charged as completed output.

Need the actual render finished?

Upload the .blend. FARPY inspects it and returns a locked quote before start. The accepted price does not increase after you approve it.
