Running 177. I have noticed that when viewing web-based video that running CPU Master and setting the NC to 1200MHz and On Demand really makes the video smoother. When I originally rooted, I installed Clockwork Mod Recovery and Nightly 177, but did not install Dalingrin's Overclock Kernel. Therefore, everytime the unit boots, even though I have OnBoot checked in CPU Master, it reverts back to the 800MHz setting. Not sure why. The Dalingrin's OC was mentioned here: Download Dalingrin?s 1.1 GHz overclocked Froyo/CM7 kernel for Nook Color Download Dalingrin?s 1.1 GHz overclocked Froyo/CM7 kernel for Nook Color ? AddictiveTips Can I safely install this now, and will the max I can get from the CPU be 1100MHz (instead of 1200)? Any advice / insight appreciated.
