AMD 6700 XT ComfyUI setup hits HIPBLAS error despite gfx1030 ROCm override
God_Hand_9764 · reddit · 2026-10-01
A user is trying to run ComfyUI on an AMD 6700 XT (unsupported gfx1031) under CachyOS Linux. The known trick is installing gfx1030 ROCm/torch builds and setting HSAOVERRIDEGFXVERSION=10.3.0, but every workflow fails with rocblaslt unable to load TensileLibrarylazygfx1030.dat, followed by HIPBLASSTATUSINVALIDVALUE from hipblasLtMatmulAlgoGetHeuristic. The commonly suggested TORCHBLASPREFERHIPBLASLT=0 env var doesn't help either; the post asks anyone with this card working for a fix.
