I do notice the 'stepped' speed (forget what its called) when using
Cpu-z. When idle it shows 2000+ mhz and multiplier of 6 and under
load goes back up to 9x and the correct speed. I did a quick test
using a lower multiplier and higher bus speed 8 x 450 which as my
calculator recons is 3600 which I couldnt get past before. System
booted ok but 3Dmark05 just crashed out back desktop after few
minutes. CoreTemp and cpuz misread the speed though and kept it at
9x450 = 4050mhz but temps were showing in the low 70s which scares me
a little. Going back to the BIOS shows the 8x450 settings are saved
ok. I had also raised vcore temp to 1.5v as a test - have now lowered
it again.
