In P5KPL-CM vCore can be only set by auto mode. But hav other adjustment features like memory dual voltage, VTT_CPU core or GTLRef, NB 1.25 over voltage, SB 1.5 over voltage etc. are present. Memory dividers, latency and CPU FSB ratio settings r too available.
If vCore adjustment was manual, the P5KPL-CM would hav been the best vfm mobo IMO.
