Original GitHub issue: https://github.com/ollama/ollama/issues/10033

ollama only supports HSA_OVERRIDE_GFX_VERSION for all GPU's

rocm supports HSA_OVERRIDE_GFX_VERSION_%n for individual GPU support

Supported added to ROCm here: https://github.com/ROCm/ROCT-Thunk-Interface/pull/104

ROCm now supports independent overrides per GPU by setting HSA_OVERRIDE_GFX_VERSION_%n environment variables.

e.g. HSA_OVERRIDE_GFX_VERSION_1=10.3.0 would force gfx1030 on GPU 1, while GPU 0 would utilise auto-detection for supported gfx version.

From my testing Ollama can easily support this with minimal changes.

This has previously been brought up in https://github.com/ollama/ollama/issues/8473
