AFAIK all new Ti NVIDIA cards and even the newest 30 series are hashrate limited and there hasn’t been found any workaround yet. Nothing will let you break the limit, no driver 470.05 magic or HDMI dummy plug yet. That ‘hack’ works only for 3060.
If you bought this card for mining, you can try to swap it for a 3080 (not hashrate limited) or hope a workaround is found soon.
