I have an Acer Aspire 5100 with a Phoenix BIOS. It came with an AMD Turion 64 single-core processor; I decided to upgrade to an AMD Turion 64X2 TL-64 dual-core processor. The computer recognizes everything but the processor model: In Device Manager it says “AMD processor model unknown.” The computer recognizes both cores of the CPU and gives the correct clock speed. How do I get my computer to recognize the processor model?
First, Kevin, props for upgrading a notebook CPU. The problem you mention can happen if your BIOS revision predates the introduction of the CPU you’re using. To fix this, download the most recent BIOS revision for your notebook from Acer (http://us.acer.com/acer/service...)—as of press time, that is v3.13, released in March. Of course, it’s not the end of the world if your computer doesn’t recognize its processor’s name, as long as it gets the cores, clocks, and voltages right.

I installed a new processor before upgrading to WIN 7. Both the motherboard and Windows didn't recognize it. Updated the BIOS and solved that problem. Then had to call Microsoft to reactivate.
