Yes - I think a big vote of thanks should go to *Jeffrey Lee* in particular who has done almost all this work. I think there is a lot more to come for all hardware running RISC OS 5. Since I installed the Apr 17th ROM version last week, things have been fine operating at the higher speed. Remember that the new OS has the filecore memory leak fixed so a fully functional !NewIcons can again be used. I have also been running a little CPUtemperature app to monitor any heat effects. When the ARMini is idling, the cpu temperature is below 50C. When running flat out ie the cpu usage is effectively 100% for some seconds eg rendering a large complex web page or processing a large image, the temperature rises to about 61C. Since the BB specs give an ambient operating temperature range of 0-85C, then there is little danger in using the higher speed. By the way, !TaskUsage will give an indication of how hard the cpu is working. -- Chris Johnson --- To alter your preferences or leave the group, visit //www.freelists.org/list/armini-support List-related queries to info@xxxxxxxxxxxx
