When I've changed the mpurate I've seen a corresponding change in bogomips. Did you check you dmesg output to see what the kernel commandline looks like? ----- Original Message ---- From: Tom Calef <TCalef@HatchScience.com> To: General mailing list for gumstix users. <gum...@li...> Sent: Mon, January 10, 2011 3:16:43 PM Subject: Re: [Gumstix-users] Overo FE - Clock wont go above 500MHz!
