Test: Athlon XP 1900+ Overclocked At 2000+
All the contacts have been properly connected - to keep them that way you can also apply a strip of tape on top of the connections. We installed the processor in our test board, an Epox EP-8KHA+ with a VIA KT266A chipset. The following images are proof that the multiplier is now freely adjustable.
The multiplier is now freely adjustable in the BIOS menu.
The multiplier 12.5X isn't available on our board - the CPU interprets 13X as the field value. This reading is incorrect and should be taken care of by the BIOS specialists at Epox.
Modifying the core voltage in BIOS to overclock the processor.
To pump the Athlon XP 1900+ up to 2000+, we had to raise the core voltage to 1.85 Volts.
A display with the new clock speed and multiplier setting under Windows 98. After BIOS shows the Athlon XP as having a 1666 MHz clock speed (Athlon XP 2000+), you can boot up your operating system (Windows 98 SE in this case). The popular tool, WCPUID, offers the following data: core clock speed 1666 MHz, multiplier 12.5X and front side-bus speed of 133 MHz. Made it!
