Hi NB frequency and HT or FSB which one should be higher

hi i have pile driver fx 8350, 890fxa-gd 70 and 16gb 1600mhz of ram. my bios state that north bridge must be greater or equal than HT link or FSB speed. but with this my NB cant move above 2200 even if i increase it to 2400 or 2600 in bios it still read it as 2200 on windows but my HT link speed or FSB frequency can increase to 2600 MHz sometime my NB and HT speed readings are the same even if my NB speed is at 2800 MHz whiles my HT link speed is at 2300 MHz. on windows my both HT OR FSB SPEED AND NB SPEED READ AT 2300. SO I WANT TO KNOW WHICH ONE SHOULD BE HIGHER. AMD CUSTOMER SUPPORT SAID HT OR FSB SPEED SHOULD BE HIGHER THAN NB SPEED? IT'S TRUE!
