Asus P8H67 with 2500k, high energy consumption

The problem is as follows Win7 64 in idle uses about 25W, Suse 12.1 48W which is a huge difference.
Numbers taken with same hardware and same measuring device(not the best but hte difference speaking for itself)

As i use it as a Server with lots of idling it does matter.

Any ideas?

You are probably using the intel i915 graphics driver. Then it’s a known issue with newer kernels. Try to boot with this kernel parameter:

i915.i915_enable_rc6=1

This is reported to help if your BIOS supports it. https://bugzilla.novell.com/show_bug.cgi?id=717454

That’s it.

Power minus 22W, sensors shows coretemps down 10°Celsius compared to before.
