C2D 6750 slowed to 266MHZ fsb speed

Hello,

I built my first computer a while back and had quite a few difficulties. I used an asus p5wdh deluxe mb, with 3GB of ram and a C2D 6750 2.6GHz processor. In the begining the MB defaulted to the incorrect voltage for the ram, and after I figured that out, I still wound up having the slow the fsb speed from the defaulted 333 to 266 in order to make it stable. Now the machine is very stable, but I would like to increase that fsb speed. The max available with the mb is 5 hundred and something. This confuses me more because I think it should be higher. Does anyone have any ideas? I can post pics if need be. Thanks in advance for the help.

it is split up into 2 1GB sticks and 2 512MB. It is dual channel.

Cool N Quiet doesn't seem to make any difference with the speed of the fsb. it does make it quieter when it is enabled though.

I know the settings are in there, I know where they are, I just don't know how to set them so that it will be stable, but will not be so slow.

Thanks

Hmmm.

Stock speed should be 2.66 GHz at 333MHz X 8. If SpeedStep kicks in, the multiplier will drop to X 6. "Cool 'n Quiet" is the AMD equivalent.

The first thing to do is to get the system working a the stock frequency. So, first, clear the BIOS and set factory defaults.

Standard default values for RAM voltage is 1.8 volts. A lot of DDR2 RAM requires high voltage. Set that.

What kind of RAM do you have?

I will reset bios and ram voltage to 2.1

Thanks
