I haven't seen this, though I imagine it is possible, but perhaps CPU-Z is not properly reading your current settings.

I'd set the BIOS to stock, run superpi (or some other benchmark), then set your overclock, re-run the benchmark and see if there's a difference. If there is, it's a mis-read of your settings. If not, then something funny is going on with the BIOS.

I am having trouble with the small size of that screenshot, but NVIDIA System Tools is definitely not there, nor are there any other programs installed that could be reverting the overclock back to stock behind your back.

However, I think guyladouche has the right answer because then you'll see if these readings in Windows are B.S.

Wow. Well thanks for turning me on the superpi as it gives results. the other programs i ran just tried to lock things up. i did not run long tests because i am impatient at the moment but a 4M test took 1:39 at 1333mHz and 1:42 at 1550mHz. thats slower. something is not right. perhaps i need a bigger OC or longer tests but from the looks of it something is not working right. especially if most everyone else sees the OC using the regular programs in Win 7

I hate to ask this, but which power supply do you have? What's the brand and model number?

Also, what else is in your system besides the E8400?

Looking at that CPU-Z screenshot, it looks like everything is at stock settings.
You said that you bumped the voltage up, right?
From what I can see, it is showing 1.1v, which may be the default voltage for the processor. So windows doesn't think the voltage is even increased. What did you increase the voltage up to?

Did you install any utilities from the driver CD from the motherboard? Did you install any sort of dynamic power utilities?

What's interesting is that on Sandy Bridge setups, windows 7 only reports the default speed, while cpu-z shows the overclock. But on older socket 775 boards, windows 7 shows the overclocked speed. Go figure...

I know it's not speedstep that's causing your issue, as the CPU would be running at 1.6-1.8 ghz.

I'm almost certain this is some sort of driver or BIOS problem. Have you updated the BIOS To the newest version? Windows is not supposed to have control over the FSB and voltage by itself.

Try going into the power options and set everything to max performance, if possible.

I must say I've never seen this problem before.

*edit*
Make sure that there is no option turned on that says "CPU speed controlled by OS."
Also:

Run a superpi 1M at the 1350 FSB speed (real FSB 1350/4), then at the 1600 (400 fsb) speed.
You should see a noticable difference, with the 400 FSB being lower in seconds, of course.

Saw some other threads with your problem, but one person said his benchmarks DID Increase:
http://www.tomshardware.com/forum/25...rclock-windows

And try HWinfo32 to see what that shows you. Also, run realtemp and the newest version of ThrottleStop, and see if the CPU is actually running at full speed.

I think Falkentyne is on to something here. So, I recommend typing edit power plan into the Start menu, and then clicking Change advanced power settings in the control panel that appears.

Now, in the new window that appears, scroll down to Processor power management. Expand it and use the following settings:
  • Minimum processor state
    • Setting: 100%
  • System cooling policy
    • Setting: Active
  • Maximum processor state
    • Setting: 100%

Then click Apply (this is one of the rare times when clicking Apply is absolutely required) and then reboot. After Windows is done starting up, check it again to see if it's any different.

Update:

When I go to Processor management, I only get:

System cooling policy
* Setting: Active

and not the other two options. What could this mean?

Also, I ran the 1M test at both 3ghz and what should be 3.6ghz, and I got 16 seconds for both. However, I think that either CoreTemp or CPU-Z (i can't remember) is showing the change in voltage.

In my P7N bios, you dont set the exact voltage, but rather the voltage change over VID. So, in default 3.00ghz my V is VID = 1.10V.

When I change FSB to 1600 (3.6ghz) i also added + 0.1875V for a total of 1.2875V. In CoreTemp/CPU-Z, i see a voltage of 1.280V (for droop).

I dont think i installed any sort of power management software.

Also, I cant ever recall updating bios on this system cause i was afraid it will do something wrong. Am i safe to update? How can I tell if i dont have the latest? Will this really help? It seems like Windows is doing something to change speed.

thanks again yall.

so do yall think i have chance of fixin this? or is it time to give up overclockin?

i had it going good up to 3.6 in XP and bought a 560ti videocard with hopes that my OC wasnt gonna bottleneck me. but now back at 3.0 with a E8400, i cant help but feel i shoulda got a crappy card to match my slower cpu speed.

thanks yall
