Frequency of HP Prime
Hi all
I found this info on the web. What I not know is the possible to have two frequency modes. Is it posible to switch between? Wich commands? Thanks for any help.

RE: Frequency of HP Prime
I think that the uP speed is locked on the kernel of the Prime OS, nothing to do for now.

RE: Frequency of HP Prime
Hello,
Prime runs at 400Mhz. It will scale CPU speed down when not in use, but that is it. There is no user controllable way to change the CPU speed. Cyrille Although I work for the HP calculator group, the views and opinions I post here are my own. I do not speak for HP. |

I can give examples of programs that sometimes runs for 10 seconds and sometimes for 7 seconds (if you run it several times without any modifications). So the scaling down also happens (sometimes) when performance is required and program slows down. Piotr Kowalewski |
