I have a Phenom II X4 965 and an 890GX mainboard with HT 3.0. I've never OC'd before and I was messing around with the HT link speed and found that it seems to be capped at 2200Mhz. I have the NB and HT link both set to 2600, but it still won't go past 2200Mhz. I'm pretty sure I'm missing something simple, but despite my Googleing effort I can't seem to find a solution besides raising the FSB. My bios lead me to believe that I may be messing up some special ratio.
