@mitu said in RPi overclock question!: The current stable kernel/firmware limits the GPU overclocking. I think a new firmware is necessary to be able to overclock the GPU again - there was a forum topic a few days ago with details. Why are you overclocking your PI ? @mitu I'm overclocking to increase dreamcast and N64 performances. I noticed that with that OC values my pi stays under 70 Celsius degrees and dreamcast games run very well. I hope to gain some frame overclocking GPU as well but from what I understood it's not so affecting.
