However, there were unique events of voltage-related-only throttling reported by GPU-Z: There had been power throttling, and not much that can be done about that (the card was already at the 123% power limit). The next step is to compare full stats before and after the cable swap. I need to analyze more data, and that will take some time, since I do it in my free time. However, the voltage in 8-pins is neither perfect nor equally stable across all 8-pins, so I am still looking at that. Thus, I take it as an empirical fact that the 8-pin #1 is the one closest to the GPU. That flattened the voltage in the reported 8-pin #1 SIGNIFICANTLY. So far, I replaced the PCIe power cable to the 8-pin connector that is the closest to the GPU. No worries about this, I am conducting own research independently of what comes in here, and will report. My question is, does someone here know how GPU-Z 8-pin indexes #1, #2, and #3 map to physical PCIe power connectors? I collected the stats for the three pins, and that yielded interesting information: the 8-pin #1 underperforms. I've started observing the perfcap reasons in GPU-Z, and something interesting came up.
