Windows 7 Win 7 wont recognize AMD Processor

[snieves]

Hi guys,

Just installed win 7 last night and found i had this problem. My processor is AMD Turion 64 x2 Mobile Technology, and it only recognizes 1 of 2 Processors. In the task bar as well it only displays 1 processor, and its obviously running high most of the time.

Maybe you guys can help me out!

Thanks,
Sean

Here's how to enable dual core cpus.

I had the same issue and found this on techrepublic.com

You need to rename the HAL.DLL (located in C:\windows\system32) to HAL.BAK then copy HALMACPI.DLL to HAL.DLL. This installed the multiprocessor version of the HAL and enabled 2 CPUs to be recognized in all of my applications properly.

Since HAL.DLL is not normally editable in a running OS, you have to boot up off the Vista (Windows7) CD and go into Repair mode and to the Command Prompt to make these changes.

This will fix that problem.

I have the same problem. I made a thread.

I can't find HALMACPI.DLL in my System32 folder. Only HAL.DLL

I wonder if the OP got it to work...

I believe I found it on the install disk. You might also be able to find it on the web for download.
