Tip #1. CPU Power Saving Throttling (Bios related)

Disable
  • AMD Turbo Core Technology
  • APM (Application Power Management) *disabling the AMD Turbo Core Technology via AMD OverDrive utility will also disable APM)*
  • Cool ‘n’ Quiet *I actually keep this enabled so I don't waste power since high clocks aren't needed under low loads*
  • CPU Thermal Throttle *be careful keep an eye on your temps, especially core temps, leave this enabled if your not the cautious type* (FX-8120 < 61C, FX-8150 <61C, FX-6100 <70C, FX 4100 <71C)
  • Core C6 State
  • C1E
  • Enhanced Halt State
  • Any other Power Saving Features in your bios, usually under CPU Advanced, Google them first.

Enable
  • Load Line Calibration, play with this setting until you get stable voltages under load, remeber every bios is different, some might even be better with it disabled, but most best enabled and manually set.

Notes
*Ensure that CPU NB, Memory or HT Link values are running at default stable values.*
*CPU / Chasis Fan Control (set to full speed for best cooling, if too loud play with the manual speeds.)


Tip #2. CPU Load Throttling (Bios problem)
  • Get AMD Overdrive and Open and Enable Turbo Core Control then Push OK then Open and Disable Turbo Core Control then push OK then exit AMD Overdrive.

Now test see if it still throttles. If this works then is most likely a bios issue, and you'll have to do this each time you restart. If it doesn't work then possibly from temps.

Known Motherboards with this problem
ASRock 880G Pro3 Bios 1.40

Known Fixed Motherboards & Bios Versions
Coming soon.....


Tip#3. CPU Temp Throttling (CPU/Mosfet / Board)
  • Get High End Heatsinks/Cooling for your CPU and your Mosfets.

I really think this post should be sticky one, and thanks again the tip with the AMD Overdrive really help me out with my speed and stability, now Im running 4.0ghz stable with even less voltage and a more cooler temperature.

It looks like my problem was that disabling AMD Turbo Core on bios does not work, you have to open AMD Overdrive and enable/disable it from there and then you will make the CPU reach its full speed all time, before the speed was throttling back to 3.4-3.6ghz, now I have 1.3v and 4.0ghz and its running very smoothly.

And thanks to this I have submited the case and call Asus service and tell them the problem with the bios so they can fix it on their next update (Hopefully)

Cheer!

before this turbo core tip i was getting 5.3 on cinebench at 4.0ghz or 4.2ghz, now Im getting 6.5 on cinebench and more stable and cooler cpu temp!

Yea it seems most of us that actually do everything right get the same problem, CPU Load Throttling (Bios problem) and the fix was a simple fix but a pain to do everytime in startup, I actually made AMD Overdrive start on startup with windows to make it a little faster to do.

Tip #2 will be the fix for most everyone who knows what theyre doing. Which means you should probably tell your motherboard manufacturer about it so they can fix it on next bios update.

If anyone knows anything I dont know or forgot to mention please let me know and I'll update the original post.

Also if your problem was fixed with Tip #2 please post your motherboard, and bios version so I can keep a list, might help people who have the same board, and when they release a bios fix please let me know so I can post the bios fix version.

Load Line Calibration, play with your this setting until you get stable voltages under load, remeber every bios is different.

On the lower end ASRock boards do not do this. It will cause massive vdroop and total instability. Voltage actually gets a slight boost with it OFF. Dont know if it is a BIOS issue (on means off and off means on) or what.

FX-4100 = 71c max

HP-UX. I came, I saw, I was sad it would not run on my X86 box.

Hmmm...interesting...IIRC, LLC ON is 0%...are you sure it's 0% and not 100%?

I actually have a fairly low end board ASRock 880G Pro3 and I get better stability overclocks with it enabled and set to 1/4, but as I said every bios is different so the user should play with it to see what gets them the best results, Enabled usually better but some may have better results with it disabled, I dont know every bios some probably need bios updates to fix alot of issues.

Oh and thanks for the FX-4100 max temp updated it.

The 970 extreme series may be backwards. With it on I got vdroop, with it off I got a voltage boost under load.

You might try enabling it and manually setting it to one of the manual settings. Not sure what bios you have nor the options but usually there is manual settings to chose from.
