However, did you freshly install Windows, without Tools? Some can change the Power Options of Windows. Motherboard tools or AMD Catalyst Control Center (the so called "Fuel" component), where you can set your CPU speed manually (min/max).

Check this and try to reset your Power Options profile to defaults too!

 

C6 Mode

APM (AMD Power Management)

Cool n Quiet

AMD Turbo Core

Sometimes Turbo and/or power saving methods do not work if not all these options are enabled.

 

 

Tader, once again, do we have to elicit all the essential information from you? What m2 device does not show up where (in BIOS or Windows Setup [which Windows version {which driver do you use}])?!

 

 

And for the Hyper Transport speed, forget about 2600 MHz! The AMD 970 chipset does only support 2400 MHz and it is no use to raise it anyway, especially if you just have one graphics card, there is absolutely no benefit. You even could lower it further with no impact at all. And raising it to 2600 in AMD Overdrive is just overclocking it. It may work or not - an voltage increase of the HT Voltage is recommended though, from 1.2V to 1.25 or 1.3V at max, if you get bluescreens after setting 2600.

 

Remember, OC is not ensured to be OR KEEP stable. For the sake of your important data, don't use, copy or do anything with important data, if you are not absolutely sure your OC is rather stable. You could end up with corrupted data.
