CPU running at half speed =(

[alpha06]

hi
i have this problem on my desktop P4 2.80ghz (northwood) cpu , on the boot up screen and in windows system properties as well as some others benchmark applications the cpu speed is shown to be 1.40ghz instead of 2.80ghz, my mobo is a Soltek sl-85erv2-c
i've updated the bios and the problem still stands can someone please help?

thanks in advance

This is not a known issue with the sl-85erv2-c.

It is good to hear that you have already updated your motherboard BIOS and drivers.

I would recheck all motherboard jumpers and BIOS settings.

With the jumper settings, I would pay special attention to JFSB1.

In the BIOS settings, I would pay special attention to the setup for CPU Frequency/Voltage Control.

Just out of curiousity, I would also play with Soltek's RedStorm2 Overclocking Utility.

If all of that fails, I would Contact Soltek Support.

I'm assuming that you have confirmed the identity of the CPU using the information on the chip itself?

Although this is hopefully a simple case of incorrect jumper settings, incorrect FSB setting or a driver problem, there have been cases where chips have been mis-sold. If you have the technical knowledge to safely remove the heatsink and check the chip then it may be worth finding out exactly what your CPU is, though the tools listed on the page below may be able to do this job for you:

If you still cannot get an identification of a 2.8GHz chip, then I would look at contacting the vendor.

Have you always had this problem or is it recent?
