All you have to do is set the HTT multi to a range that is stable, your computer wont boot if your HTT is set improperly. It wont harm anything if you try both settings. Most likely it wont boot at the 1080 setting, so try both.
HTT does nothing for performance either, so dont think of overclocking it as a way to increase speed..

exactly, it just needs to be set where YOUR system will be happy and stable. Seems it likes the higher side rather than the lower...good work.

nice work, very nice, another opteron dual core overclocking nicely...and cool to top that off....happy to see another z9500 user. Keeping that dual core cool on a nice overclock, doesn't get any better than that...
What voltage are you running, got any screenshots of cpuz or anything ?

nice screenshot you posted, nice low volts also......Shoot for 2.8, might take some voltage..
that's my favorite dualcore chip.
