No, you should really get the rated speed on each core, 3.2GHz in this case.
HT link speed should be 2GHz, not 200MHz. Bus speed should be at 200MHz, with a 16x multiplier. (200*16=3200)

If you can't set it up in the BIOS, BN probably is right in that it needs a BIOS flash. I never used AMD, so I'm not really sure; Intel, at least for Core2, simply has the front side bus and a multiplier to deal with. With AMD, I guess the hypertransport thing comes into play as well.
