anzial: RealTemp reports your average CPU multiplier. Depending on your C1E / EIST bios settings and how the Windows power options are set up (Minimum processor state), you might see the multi jumping up and down at idle. I left RealTemp like this because it best shows you what's going on. If EIST and your power options are set up properly, at idle, you should have a consistent multi of 12.0 on Core i7. If you don't want your multi dropping at idle then you need to make sure SpeedStep is off and Minimum processor state is set to 100%.

Sometimes CPU-Z does some averaging and reports the multiplier at its full value but the displayed MHz will be based on some sort of average. Your screen shot is a good example. CPU-Z shows 133.3 X 22.0 which doesn't equal 2907.9 MHz which is displayed.

rge did a lot of Core i7 testing for me so I think you should be able to trust RealTemp MHz as well as temperatures. Here's the most recent release:

RealTemp 2.70 does not properly support Core i7 so don't use that version.
