CPUZ is able to get my Processor name so it must be possible.
Does someone know what API Command I need to use to get the CPU name?

(In my case it is AMD Athlon XP)

 ! MOV EAX, 0

 ; the VendorID is now stored in EBX-EDX-ECX
 ; very important, first move all results to a save place.
 ! MOV [p.v_Zeiger1], EBX  ; move ebx to the buffer

It's "safe place", not "savely place". (No offense intended).

What is

!CPUID

doing?

interesting ...

but is possible to read the standard level 0000_0001h ?

Is there any Win API Function to do the same thing without using ASM, or any other possiblity to get the CPU Name?
And I don't really get what

Code: Select all

!Mov EAX,4
!CPUID

is doing.

@PB
The result is the CPU at Windows-Installtime, but if you change the CPU, this
Registry-Entry was not updated

@Konne
CPUID is the only save one for this information
