Incorrect jumpering or rogue CPU?
I have just built a new system using a Gigabyte GA7AVXP motherboard with an Athlon XP2100+ and 512 Mb of PC2700 SDRAM, running XP Pro, however on firing it up the processor is being identified as an XP 1500+, running at 1.31 Ghz rather than the expected 1.73 Ghz for the 2100+. Can this be caused by e.g. incorrect jumpering on the motherboard or is the processor in fact a 1500+ in the wrong box?
