We'll see when you get home at 5AM. I wouldn't understand why the BIOS isn't detecting the stock speed. I am thinking that you where looking at the base clock speed. See, CPUs have a small base clock speed and then they are multiplied to get the advertised clocked speed. So, I am thinking that you saw the base speed instead of multiplied speed.
I will be home in a hour tops maybe even sooner.... still hungover from last night... worst day of work ever... but i have been looking things up online have have not been able to find anything about it... and i remember where it said 800 MHz it was grey i could not change the speed of it...
is your motherbd rev 1.01g and did you update the bios?
What you're seeing is typical of a motherbd that doesn't supply dual plane power so I suspect that your MoBo isn't capable of running that processor. IE - you motherbd is not the rev 1.01g thats needed.
Select BIOS then use the latest BIOS version and click the Global link (one with green disk). Extract the BIOS file to USB flash drive or burn to cd. Boot the PC (with USB/CD in) back into the BIOS and go to Tools then EZ Flash 2. Use TAB key to change to the proper drive (if not default) and the BIOS file should appear. Select it and follow the on-screen instructions. This is most like what is causing the problem.
