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.
