correct voltage for Intel Core2 Quad

Hi,
I haven't found my question in the search and hope that it's not redundant.
My problem:
System works fine after it has booted up but most of the time, I get the message:"Overclocking failed. Enter setup to re-configure your system. F1-setup or F2 to load default values to continue".
I have replaced the Corsair Ram, reset the jumper, made sure the C-Mos Battery is fully charged.
Corsair Tech Support advised me to change the voltage (In Bios/Advanced) to 1.7 Volt.
Now I'm getting the message:" CPU over voltage error".
My CPU doesn't give me any clue as to what voltage it is supposed to be set at.
Does anybody have any suggestions??

CPU:Intel Core 2 Quad Q6600 2.4 GHz LGA 775
Mobo: P5K3 Deluxe ?WiFi- AP
Ram: Corsair Twin 3X2048-1333C9/ 2GB (1 each) DDR3
Video: XFX GeForce 8800 GT
Power Supply: Thermaltake Toughpower 700 Watt
HDD: WD 500 GB 7200RPM
DVD: LG 18X Super Multi Re-Writer

I hope that this gives you enough info.
I'll appreciate any suggestions you have. Thanks in advance!

If you have a B3 stepping then go to this link: http://processorfinder.intel.com/d [...] Spec=SL9UM

If you have G0 stepping then go to this link: http://processorfinder.intel.com/d [...] Spec=SLACR

Set the CPU voltage back to auto and see what happens. As you can see from the links above Intel shows 0.85 - 1.5 volts. You have your voltage set to high at 1.7v
I run a Quad QX6850 and it's overclocked to 3.6GHz and my core voltage is only 1.35 volts. I don't know why the Corsair tech would tell you that unless maybe he was talking about memory voltage.

This came from Corsair's web site and the tech was talking about the memory voltage.

Tested together at 1333MHz, Vdimm =
1.70V, at latency settings of 9-9-9-24

core temp has vid reading , that is the cpu voltage.

Memory voltage should be somewhere around 1.9~2.1V, depends on your memory's specification. As for CPU, you should get 3.0Ghz easily just from the stock voltage. If not, slightly bump your vCore to 1.275.

Alright. Thanks man.

anken,

Now, try lowering your core voltage a little at a time. The lower the voltage the cooler the core will run and 1.5v is max for that processor. Like I said earlier, I have mine overclocked and my core is at 1.325v's. You can probably run yours at 1.275 to 1.35v's with no problem. That's if you don't overclock. Cooler is better.

1.275v is a starting point. If it is stable fine if not then raise it one notch until it becomes stable. Or you could just set it to AUTO and let the BIOS regulate the voltage. Right now I am not overclocking and my CPU voltage is set to AUTO and PC Probe shows the voltage at 1.27v.

I run M.S. Flight Simulator X on mine.

I have had no problems with FSX. I have had only a few small problems with Vista Ultimate 64bit. Granted, I had to purchase some new software because some of my old software would not work with either Vista or the 64bit. I have installed the Vista SP1 Release Candidate and it made a big difference in the OS. I have not had any problems since. I can honestly say that I will not go back to XP.

I am so glad I could help. Should you have anymore problems in the future just post them on the forum and someone will be glad to help you. I think this forum is the best there is and there is a lot of knowledgeable people on this forum willing to help. "Good Luck"
