Don?t Believe Your BIOS: MSI?s K8N Neo 2 Falsifies its Multipliers
www.sudhian.com/showdocs.cfm?aid=616
Potential real issue for Nvidia and/or MSI if true what Joel has found
Example from article:
According to CPUID and the motherboard BIOS itself, we are adjusting CPU speed in half-multiplier settings and raising bus frequency in a standard pattern. According to Everest, however, our half-multiplier settings do not exist at all. Instead, when a half-multiplier setting is called for, the motherboard ?approximates? the value of one by raising the front side bus further. This occurs ONLY on half-multiplier settings and occurs consistently; we tested all the way down to 8.5x and at a variety of bus speeds between 200 and 250 MHz. The same effect was always observed without fail?but only by Everest.
