ASROCK 970M Pro3 CPU Throttling?

I'm almost positive the "Bulldozer Patches' have now been either distributed via Windows Update or rolled up now onto pressed discs.

These were caught immediately after release.

If only one of the 2 20A rails is being used to power the system or the load is severely imbalanced across the 2 rails it is quite possible it could be causing an issue. You did bring up a good point with the windows 7 updates as well.

Well I for one hope that you'll chime in, wardog, if you feel like I'm writing nonsense. You're probably the more experienced of us two, and I think it benefits the OP to have more than one person helping him. Furthermore, if I was a bit blunt before, I apologize. I was in a hurry and frankly the idea that ASRock would do such a bad job in product testing irks me. But I won't go further into that now.

TechLord, your system specs seem okay. Also, based on these articles your system's power consumption under load should be lower than my system's (although the absolute numbers are probably different for both):

Since your CPU and socket temperatures seem to be doing okay, I'm assuming that the airflow inside your case is not terrible. Unless the VRM heatsink is not properly attached, it don't think it should be overheating. If you want, you could try opening your case and positioning one of the case fans (assuming you have two) so that it blows air straight over the VRM heatsink. Then run Prime95 and see if the problem persists. Before you open the case, however, you might want to try the following things.

The Turbo Core on your FX-6300 works a bit differently than on my Phenom II X6, where TC is activated when roughly half of the cores are loaded (it's a soft limit, though, so at times four cores may be running at TC speeds). You should see the 4.1 GHz when only two cores are loaded. Prime95 loads those two CPUs so fully that the OS and other programs you may be running in the background probably load the remaining CPUs enough to prevent this mode from activating. On my CPU I can only run two workers at a time in order to run them steadily at TC speeds. If I try with three workers, I only see occasional and brief TC speeds. So, try running Prime95 with only one worker and see if you'll see that 4.1 GHz. If you do, then the reason for not seeing before is what I said above.

Are you running Windows 7? If so, have you installed the bugfixes that are supposed to fix compatibility issues with FX-series CPUs?

Also, see if the trick mentioned here helps you:

Yea. The Internet does indeed when one searches it support both side of this coin.

You're in good hands with PetrolHead here now to assist you.

Oops. My bad. I saw edited on the bottom of the post above this and assumed it was the OP.

PetrolHead, I'll let you assist the OP as we two have differing opinions on this. Not that I would not nor could not help him, instead only that you are of the inkling these perform ok.

I'll bow to your experience here and intently observe while you help the OP in this matter to resolution.
