2) Some out-of-date, but still useful info can be found here:
http://sandpile.org/ia32/cpuid.htm Search the page for "Athlon 64" and "Turion 64" (I'm not sure what means "Sempron TT00+, 64-bit"). |

Ivan2k2 - you may be able to make use of the Brand ID and Brand String CPUID instruction to get the information you need.
Brand String is a fairly new extension to the CPUID instruction and returns an ascii string identifying the CPU and maximum frequency. Check out chapters 3 and 5 of this document: ftp://download.intel.com/design/Xeon/applnots/24161830.pdf Hope this helps. Hypervista |
