Overclocking trouble!!!

First off I have a Q6600 which is supposed to be at 2.40GHz...When I open CPU-Z, it says it's at 1.6GHz...I go into the BIOS to check and it says it's running at 2.40GHz with CPU Clock Control OFF. When I turn ON CPU Clock Control, it says it's running at 1.6GHz. I then bump up the FSB speed to 2.40GHz and save changes....then my PC shuts off and then turns back on again by itself...I then go into the BIOS and all my CPU clock settings have been reset!! Any help?
 
When I got my Asus P5N-E 650i it did not recognize my CPU, Intel Q9300. It would report it as 2.0 GHz no matter what I did. Then I was installing all the drivers and flashed my BIOS to the newest one and the motherboard then would recognize it. I knew I needed to update my BIOS but had not done it yet. Try a BIOS update, maybe that will do the trick. Is your processor compatible with your motherboard?
 
The reason it turned off, and reset everything is probably because you have a fail safe on your mobo. In CPU-Z when my CPU is not under stress, it has a core speed of 1798 MHz with a 6x multiplier. When it is under stress it jumps up the 3000 Mhz with a 10x multiplier. Try running a stress test with CPU-Z open and see if it changes.
 
I used to have a problem like that where no matter what I put into the BIOS, CPU settings went back to normal after restart. Try removing the CMOS battery for about 10 minutes then try everything again. That's how I fixed my problem.
 
Ok update! I fixed the problem with why it was running at 1.6GHz. It had something to do with the EMIT Technology so now it's running stable at a constant 2.40GHz but another problem, I can only overclock the FSB around 2MHz. Anything more than that and my system shuts off and then turns back on again with the clock speeds reset....
 
That could be one of those safety feature that keeps your CPU from dying so it shuts down and defaults all settings if the FSB is too high for the current set voltage.

Are you at stock voltage as well? Maybe raising the voltage one notch would give you a successful OC boot

Click to expand...

I think it's running at stock voltage. How much would I have to raise the voltage to raise the FSB about 100MHz?
 
You mean raising the FSB by 100? or raising the CPU clock +100MHz? If you mean raising tthe FSB by 100, then your clock speed would be 3.4 because the multiplier on the Q6600 is 10 right?

Sorry if I typed in confusingspeak :P
 
the multiplier is 9 and I want the CPU clock to be around 3GHz so the FSB would have to be 333....333x9=3.0GHz....The FSB clock ATM is 266....
 
Oh nice, my CPU's multiplier is also 9 so I guess I could help there.

I currently have my FSB at 300 (2.7GHz clock). I also wanted 3GHz clock but couldn't get it stable. Just start at 290-300 and run 5 minutes of ORTHOS then raise the FSB by ~5 and repeat... If you get BSOD's, restarts or just random freezes, bump the voltage one notch, rinse and repeat.

Of course if you don't want to overvoltage, just play around with the FSB until you get instability.
 
Well I used EasyTune5Pro and got it up to 3GHz fine. CPU-Z and PC Wizard both show it at 3GHz. I hear people saying that using Windows based utilities aren't reliable? but it worked fine for me.

BTW Omar, get on xfire sometime that way I can ask you more overclocking questions :P
