Hi I've already wrriten a post a few days ago about undervolting the rtx 5090. The main thing that confuses me is why when setting my curve to like 0.9 V with 2900 mhz my gpu core might rehach that value under no pressure but when i turn it benchmark it decreases the voltage and the mhz also drops to like 2750mhz ? Does it work that the mhz we set for certain voltage is stable or not? I mean even acter locking it up it doesn't want to keep it in benchmark. Temps are not a problems aswell I have 1200 PSU and my card exact model is Asus RG astral. I have shared the photo of my stock voltage as well as my curve
