AMD Phenom II X4 965 black edition Running Slow :(

First I just want to say that English is not my main language :pt1cable:  and I want to apologies for all the mistakes. I'll do my best! :bounce: 

Dxdiag : pastebin

Problem: My frames are dropping in every games when the action become to intense. For example my frames are dropping under 20 in BorderLands 2 even if my specs are ready to take the max settings...

What I try:

    - Check the temperature and everything is fine (under 60 degrees with prime95) but I found something weird. With CPU-Z open during the test sometime (between 2 to 3 times per minute) the core speed drop to 800 MHz... (cool n quiet ??)

    - Check the Windows Power Management and it was already at high performance.

    - I also update the BIOS of my MSI 970A-G46

    - And now I am out of idea. :sarcastic: 

Here are all the tab from CPU-Z: imgur

Thank you in advance for any help you can provide to solve that mystery :D

The MSI 970A-G46 is a known for forcing thermal throttle on the CPU because of overheating VRM's especially with 125watt CPU's. https://docs.google.com/spreadsheet/pub?key=0AgN1D79Joo...
I believe that is what is happening with yours, if you can place a fan blowing directly at the VRM's to see if that helps you will know for sure.

I'am sorry but what is a VRM's :S Virtual memories?

Sometimes called mosfets but really are the voltage regulators, on your board they have a heatsink on them between the CPU socket and the IO panel. Increasing airflow over that heatsink may stop the issue.

Side panel off and a powerful desk fan could be enough to test the theory.

I'll try to find a desk fan but for now I think I found the problem i blew all the hot air straight into VRM's :p

Looking at your picture I see a push pull config on the cooler so with the second fan there pulling it actually leaves a pocket of air stagnant over the VRM's with a conventional cooler setup, single fan, the airflow would be more spread and moving the air around the VRM heatsink.
I have the same board with FX8350 but the cooler I have blows air down on the heatsink and keeps it moving http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Lol!!
If I just remove the small fan it should be ok? or i really need a new cpu cooler so the hot air is not blew over the VRM's ?


and i tried with the fan still the same problem :(

It may be your VRM's are already damaged and take less heat to throttle.
