Dat de athlon64 geen halve multipliers ondersteund, en dat die door de bios gesimuleerd worden met gewoon de hogere of de lagere multiplier te gebruiken en de htt aan te passen.
Traditional overclocking information on the Athlon 64 agrees that using a half multiplier rounds the memory divider—but states that the divider is rounded up (resulting in a lower memory clock than is actually predicted) not down. Based the information reported by Everest and CoreCell (plus our conversations with AMD) I chose to believe the two utilities rather than conventional wisdom. I further stated that I believed these instabilities and problems were either the result of an overeager manufacturer pushing its product to market, or unacceptably flawed BIOS engineering. In order to determine whether the multipliers were rounding up or down, we sent the board to Michael Schuette of Lost Circuits, who agreed to perform oscilloscope tests. The results of those tests are now in.
According to Michael’s tests, the Athlon 64 + K8N Neo2 does round up when a half multiplier is used, and therefore runs the memory slower than is actually reported by most utilities. Ironically, I was right to conclude that some utilities and software don’t report Athlon 64 settings correctly, but I chose the wrong set of utilities to trust.
