Ok i did some testing with CPU-Z and either my motherboard is screwed ir CPU-Z is giving me the wrong numbers
Bios FSB set at 266 and Bios Vcore set at 1.3vcore
--> Going to windows and run cpu-z and orthos
CPU-Z Giving me idle Vcore of 1.264 vcore
CPU-Z Giving me stress Vcore of 1.240 then 1.232 and 1.224 in this order and then starts switching regularly ( every xx seconds ) between 1.232 and 1.224.
I also noticed Vcore's dropping with other FSB Settings on AUTO. They always drop a bit when comming from idle. And for example my MOBO Vcore set to 1.4 shows an idle of 1.352vcore idle in CPU-Z and a stressed 1.320vcore stressed.
It got me really confused now

Is this an error in CPU-Z , Mobo , Not enough Power ?
Anyways Greetz
