Windows 7: Upgraded my CPU now it shows up as AMD model unknown help

Upgraded my CPU now it shows up as AMD model unknown help

I just upgraded my CPU to AMD Athlon 11 245 2.9GHz dual core and what a difference in speeds the only problem is a very small one when in system it shows up as AMD Processor model unknown 2.9GHz. When I run CPU-Z it shows everything about this processor even the model number but it shows nothing through Windows.
Anyone know how to fix this? I don't feel like taking my computer to the shop and paying to fix this very small problem.

What does it list for the CPU in your BIOS settings?

When you replaced the CPU, did you perform a CLEAR-CMOS (or CLR-RTC) procedure?

There's no setting through the BIOS that shows the CPU only the volts and temp.
Yes I reset the BIOS after installing this new CPU

There may not be a setting but there will be a system info page or status page that displays the exact model processor installed. It sounds like you need to update the BIOS for proper detection and support of the new processor. That or that processor isn't supported by your motherboard.

No idea if that CPU is included, but there were two bios updates from Sapphire for that board that updated the CPU microcode,

If you don't have the latest I would just go with it, as bios updates are inclusive and not incremental which means flashing the latest gets you any prior updates as well.

P.S. For what it's worth if the speed and number of cores are detected correctly, updating the bios isn't really necessary as all it will do is make the proper name appear.

I would agree with this statement.

The last update to the supported CPU list is Feb 2009 and shows two AthlonII X2's on it.

Windows reads BIOS and CPU-Z reads the CPU. If you're not having any performance issues I recommend no BIOS update. You can try going to Control Panel\All Control Panel Items\Device Manager\Processors and try a driver upodate from there.

Well I now have a new problem since late last night I get this error after my computer passes post:
The file is possibly corrupt. The file header checksum does not match the computed checksum.

I got this error so far 3 times
After a restart windows boots up normal.

OK. Is this checksum error message is being given by the BIOS (likely) or is this a Windows error message?

If a BIOS message it means the CHECKSUM, a code generated by the BIOS that represents the hardware on the motherboard, does not match the hardware that is detected on boot. And we know why that is.

If your exact CPU is not listed as compatible with the motherboard with the initial BIOS version then you will need to update your BIOS to the most recent version - provided your exact CPU is supported by the motherboard at all - as the other folks have mentioned.

If your exact CPU is supported by your motherboard with the initial BIOS version then you just need to do a CLEAR CMOS or a CLRTC on the board to update the checksum.

This is not the same thing as RESTORE BIOS DEFAULTS.

Normally the procedure is this:
  • Note all your current BIOS settings
  • Shut down the computer > remove the power cord.
  • Remove the 3.3v battery.
  • Move the CLRTC jumper from pins 1-2 to 2-3.
  • Touch a metal part of the case and Press and Hold the reset button on your case for approx. 30 seconds to discharge all power from the board.
  • Put the CLRTC jumper back on pins 1-2.
  • Replace the 3.3v battery > replace the power cord > boot.
  • Immediately go back into BIOS and reset all your preferred settings. If the CLRTC worked you will need to reset the date and time.
Some of the newer motherboards have a CLEAR CMOS button on them to do this instead of the jumper pin. Read your Manual!

Let us know what you find.

Here is your CPU support list for that board (Thank You Stormy)
http://us.sapphiretech.com/archive/gm/driver/529.pdf

Can you find your new processor on that list?

As you can see your description of "Athlon 11 245 2.9GHz dual core" is not very clear.

Is it a Athlon X2 5600+ Brisbane 2.9GHz ADO5600IAA5DO ?
