getSystemInfo API to obtain Processor description

Postby ConvertFromOldNGs » Fri Aug 07, 2009 2:51 pm

I'm looking for a way to obtain this sort of information:

"Processor x86 Family 6 Model 8 Stepping 1 AuthenticAMD ~1990 Mhz "

or even just

"AMD 1.9Ghz"

I'm currently using (GetSystemInfo in kernel32) but am struggling to interpret parts of the structure returned.

Any suggestions would be most welcome.

Hi Andrew,
You can get some of that information from this key in the registry:

HKEY_LOCAL_MACHINE/Hardware/Description/System/CentralProcessor/0

There is an application called cpuz.exe (you should be able to google for this) which can be executed like this:

cpuz -file=cpu.html

This outputs quite a detailed file in html format (which you'll have to parse in JADE, but that should be relatively easy). This contains quite a bit of information, including everything you wanted and more. From what I know this gets most of it's information from the BIOS.

I hope this helps,
Allistar.

Sorry to reply to me own post, but you'll find information about getSystemInfo at:

Thanks Allistar, the "cpuz" option sounds ideal.

I do actually make use of getSystemInfo, it's just that there are a couple of sections within the structure that I can't make sense of.
