Core speed fluctuating between minimum and my oc speed...

post #1 of 14
Thread Starter 
I'm using a p8p67 deluxe asus mobo and a 3.4ghz i7 processor.

I want it running at the oc core speed constantly for what I'm doing.

I've disabled c1e and speed step but the core speed always drops down to 1.6ghz when my software isn't stressed for a bit.

Is there a way someone could help me track down this problem?

It's not a problem, but it's an intentional design.

Is this creating problems for you? Or is it that you just don't like knowing that it's doing this?

An intentional design? Could you elaborate?

But yes it is, for some of my calculation software the calculations drop off at some points and when it idles and the complex ones flow in the software bluescreens.

It drops to a 1.6ghz speed and a lower voltage (with offset) when you are idling.

When you start doing something CPU intensive (typically around 5%) it picks the core voltage back up within a fraction of a second.

This is one reason I stay with AMD.
Yes... I realise that that was not useful to your issue.

It's all about automatic power-saving (it dynamically adjusts based on the load on the CPU).

To disable it, I think the following must be done:
  1. Go into the UEFI (the BIOS)
  2. Switch to Advanced Mode
  3. Click the Ai Tweaker tab
  4. Click "CPU Power Management"
  5. Disable "Enhanced Intel SpeedStep Technology"
  6. Right-click to back out (it's the fastest way)
  7. Click the Advanced tab
  8. Click "CPU Configuration"
  9. Disable "Enhanced Intel SpeedStep Technology" in here too
  10. Disable "CPU C1E"
  11. Right-click to back out
  12. Press F10 and then Enter to save and exit

If this doesn't work, then I may need someone else to help.

It won't work, because in these boards you also disable Turbo when you disable enhance speed step...

What benefit does the turbo function provide? Would a solution be two write something that constantly keeps the cpu usage at 5%?

All modern cpu's have some sort of power saving function.

Intel is c1e and speedstep, amd I forget, but similar to what cables said, explore around in your bios and see exactly whats enabled.

The Turbo is the Turbo Multiplier. Without it you cannot overclock. Other than the BCLK, which does not go far with Sandy.
