Ok, so in all of the BIOS and Kernel Developers Guides, they have a bios checklist and mention that you should perform CPU speed detection. It says to see the example frequency-determination assembler code available on the AMD web site but I can not find it anywhere. Any help in locating it would be greatly appreciated.
The following is from Page 327 of the 'BIOS and Kernel Developer's Guide for AMD Athlon(tm) 64 and AMD Opteron(tm) Processors". Publication #26094
12.2 CPU Speed Detection
The BIOS can use the time-stamp counter (TSC) to clock a timed operation and compare the result to the Real-Time Clock (RTC) to determine the operating frequency. See the example of frequency-determination assembler code available on the AMD web site.
