Martin said:Was the FSB speed properly read with some older HWiNFO version(s) ?
Please attach the HWiNFO Debug File for analysis.
Martin said:Thanks. What is the actual FSB you're running, is the CPU maybe overclocked ?
You might also try to disable the "Bus Clock-based" option under Settings - Safety - CPU Clock Measurement, but I'm not sure how well this will work on your system.
Martin said:Have you overclocked the FSB as well? If yes, what's the correct FSB clock ?
Martin said:Ah, so the problem is the large difference in FSB speeds measured. It seems there's something running in the system that causes interference with the clock measurement.
The only workaround is to disable the "Periodic polling" under CPU Clock Measurement.

CPU is 100 BCLK X16 to X45 at full load, but I get readings from 69-103mhz for BCLK and 1.55ghz-4.8ghz on the clock speed. I'm 100% that it's overclocked correctly and nearly positive the readings are erroneous, because whenever I load CPU-Z for a second opinion during these odd peaks and valleys, CPU-Z reports 100mhz X 45.

Which operating system do you have Windows 8.1 maybe ?
Does CPU-Z always report the correct BCLK, or can you see such discrepancies there as well ?

Martin said:By leaving the "Bus Clock-based" option enabled and disabling "Periodic polling", the BCLK should be stable and no such discrepancies will occur.
Martin said:Which "CPU Clock Measurement" options in HWiNFO are you currently using?
Does changing settings like "Bus Clock-based", "Periodic polling", "Use HPET" produce the same erratic values ?
Please enable all the "CPU Clock Measurement" options and "Debug Mode", let the sensors run for a minute and attach the produced DBG file.
