My objective was to buy a new video card that was passively cooled even though I really liked my Geforce4 Ti4200 (good compatibility & performance for the money). After looking I didn't see anything I liked, so I underclocked my Leadtek vivo Geforce4 Ti4200 to 90mhz Core and 180mhz memory (effectively 90mhz) and unplugged the gpu fan. My shuttle system is much quieter and now I can use it in my Audio Recording Studio! 🙂. I wonder how much farther I can clock it without getting artifacts? Thoughts?
