In the BIOS (1404) for my Rampage IV Extreme I have most OC-settings set to default. Except for XMP being enabled, SpeedStep turned off and C-states turned off, I havn't changed anything else. I also have a Intel i7 3960X CPU which should be 3.3 GHz default and 3.9 GHz when Turbo Boosted.
Windows are reporting 3.3 GHz
Intel Turbo Boost monitor reports "power saver" when not boosted, and 3.9 GHz when boosted. Why is my CPU in power saver mode when I have turned off SpeedStep and the C-states? Core Parking is also disabled and the Windows Power settings is set to high performance.
Asus software and the OC-key reports a constant speed of 3.9 GHz
CPU-z also reports a constant 3.9 GHz
What software is right about the speed?
When it comes to memory I have 4x4 GB Corsair Dominator GT 2133 MHz quad channel (XMP enabled and all settings correct)
SPD info and DIMM post in BIOS shows that all 4 DIMM's are installed and running at the same speed, but BIOS and Windows tells me that the total capacity is 12 GB when it should be 16 GB. CPU-z however, reports that I have 16 GB. Again, what software should i rely on?
It was the same on all of the previous BIOS versions I have used
It was the same on Windows 7 Ultimate x64 and Windows 8 release preview x64
