ok, well the story is, the dfi NF3 250GB UT has 4 sata ports, 2 on the NB, two on a marvel chip.

BUT, the 2 sata ports on the marvel controller only function to 245HTT on every board.

DFI has confirmed it is because they are not locked. so this is a hardware limit, not a bios limit.

now, examining the area, there is a missing crystal very close by. my thought is they removed it to save on costs.

so im wondering if i added it back in, could i lock those 2 sata ports? as i need them locked to be usefull since i run 350+htt.

here is a photo of the area.

may not be only the xtal that is missing. componants like resistors that lead up to the xtal could be missing as well in which case u will need to trace the circut and intstall every missing componant to compleet the circut whick would be rater hard concidering the size of the traces. not to mention where would you get the values of the componants how do you know what mhz value xtal to put in and so forth.

all oscillators are balanced with external capactitors. you'll have a hard time guessing these values. although as long as you know the required reference frequency you should be able to figure it out from datasheets.
