VIA VT5431E: Reference Board 2
This board has been developed by the chip manufacturer VIA and was meant to be a reference design for motherboard manufacturers. We have included the results of this board only as a comparison.
Exposed: Manufacturer Tricks With FSB Clock Rate
Note: X axis (core frequency) not to scale.
To ensure absolutely identical test conditions, we started our comparison by examining the FSB clock rate on all boards, because manufacturers do not always specify the exact clock rate. For example, the BIOS might show 133 MH, but when measured precisely, this turns out to be 134 MHz or more in reality. Even the BIOS reading of the processor clock rate - for example 1200 MHz in the case of the AMD Athlon - doesn't mean anything.
