Shows CPU As 2.60Ghz When 2.80Ghz (Upgraded From 2.66Ghz) PC Is A Dimensiono 4600, CPU *WAS* A 2.66Ghz P4 HT (Stock) Now CPU Is A P4 HT 2.80Ghz From An Optiplex GX270, Im Also Looking At Upgrading To A 3.40Ghz P4 HT From A Inspiron 1150 IF I Can Get The PC To Recognise The Current CPU, Also I Would Like To Know Is The PC Capible Of Using The Extra Ghz That Arent Displayed? (I Know There There - I Upgraded The CPU, I Will Add Bios Version In a Sec When I Restart After This Update, Thanks In Advance!

Select the "Start Menu."

Click to select "Control Panel." This will open a new window with several clickable options.

Choose "System and Maintenance," typically located near the top left-hand corner of the Control Panel

Click to select "System" from the new list of options

Look for the CPU's stock speed as indicated under the "Processor" heading. This is a ballpark, relatively close estimate of your computer's CPU speed, as provided by the manufacturer.

Checking the Stock CPU Speed in Windows XP

Click the "Start Menu.

Right-click on "My Computer."

Select "Properties." By default the Properties window will usually be set to the "General" tab, but if the window is set to a different tab you'll need to click on the "General" tab located near the top of the window.

Check the CPU rating as listed underneath the "Computer" heading.

Determining Real-Time CPU Speed

Go to CPU Speed Professional's website (see Resources) and download "CPU Speed Professional."

While other free CPU clocks exist, many are beta programs with glitches and unwanted bugs. CPU Speed Professional is well-known and reputable, receiving the "Vista 5 Star Software Award" according to its website.

Install the recently downloaded

" http://download.cnet.com/cpu-speed-professional/3000-2086_4-10833139.html "

file by double-clicking on it and following on-screen prompts to complete the automated install procedure.

Open CPU Speed Professional.

Click "Test Your Speed" on the main program interface.

A real-time, active measurement of your CPU speed will appear numerically, and CPU Speed Professional will also display your CPU speed on a stylish meter for easy visual comprehension.

hope this helps

In my opinion the Celeron have been lower performing processors and lower cost. HERE is and article describing the differences between the Celeron and P4

You will need to enter the BIOS by hitting delete key during POST.

Then navigate to tab System settings.
Locate the Hyperthreading field name and set it to enable.
Save setttting and exit.

Please take the time to rate my expertise, by rating this solution, its the thumbs up on the top right hand side of this solution.
Thanks

Well is a driver to enable on this site:

probably may help

either you have bought an incompatable chip for the mother board. or your power supplie is not powerfull enough I know this sounds stupid but it happened to me when I upgraded to a P4 3.6 quad core I installed the lot and it wouldnt start up I had a good power supply too Get your self at least a 500 watt PSU

Hope this helps

Probably nothing. If your system works, I would not concern myself greatly with this small detail. The system indicates a 3.4 GHz cpu installed. Your software may misidentify some of the features of your Prescott.

Intel 570J has a clock speed of 3.8Hz and has 800Mhz FSB. It supports DDR SD and DDr2 SD RAM modules. You can get the full specs from here

Since PCB 2.0 or later support HT Function

looking up the motherboard online shows that it supports the 3.0Ghz processors but only the nothwood ones, not the prescott ones. and only up to 800Mhz side bus.

Hope this helps, sorry if your cpu is a prescott, if it is a northwood RMA it for a new one.

looks like you limited to the p4 Prescott, this is a p4 list of the cpu support from asus. I also looked at their bios update page and found no bios improvement. if you can move to the 775 platform ,you can move from p4. otherwise, the p4's are still  good . I had the cpu that is the 2nd one down. 3.2ghz oc'd to 3.8ghz full time with a max of 4.0ghz on air[775 platform] quad-pumped gave me a 1001.3mhz FSB
