I'm running a Prime RTX 5080 OC that maxes out at 1.045 V on the GPU core under full load. I'm trying to understand whether this relatively low voltage suggests a higher-quality or bad silicon bin, or if it's more reflective of factory VBIOS tuning. Have other users with different voltage ceilings seen better undervolt stability, thermal performance, or overclocking headroom?
Please do share your thoughts and what kind of voltage you guys are getting—especially Prime RTX 5080 owners! Have you noticed any correlation between voltage ceilings and undervolt stability, thermal performance, or overclocking headroom?
Would love to see data from tools like GPU-Z, VBIOS mod results, or even just real-world benchmarks. Looking for patterns across batches and vendors grounded in teardown-confirmed evidence.
