OC on the NB frequency

[Deadstick50]

So, I keep reading some conflicting advice on where you can run the NB frequency as compared to where you can run the HT on an AMD chipped MB.
And I wanted to ask you more experienced overclockers what is the real deal, also can you advise me on what kind of voltage setting i should put on the various chipsets?

My specs are
Asus M4A785TD-V EVO
Athlon IIX4 620
Corsair VS2GB1333D3 G RT 2GB

currently running
250Mhz ref clock X13 CPU @3.25Ghz @ 1.4v
HT @ 2000 and NB @ 2250
Memory clocked down one step to hold it @ 1333, but has tighter clocks @ 8,8,8,22,30
Oh, also overclocking the onboard vid @ 650Mhz

So can I go higher NB, do I need to do a volt increase on anything else?

Thanks in advance, Dead
