yo~.. i'm new in amd....

as what i know... , the hypertransport thingy should'nt exceeds 1000mhz as it'll cause unstable overclocking....
hmm... what if my hypertransport at 1091mhz ... while prime stable...
will it do any harm if i let it stay at 1091mhz which is exceeding 1000mhz?

while another thing i wanna ask is that.. what's LDT to Northbridge.. and bla bla bla to southbridge?
