How to lower the HT in AV8?

[TerminatorEX]

Hi im trying to OC my Abit AV8 with AMD 3000. I dont c HT setting in my bios, the only thing I see is LDT and it can be varied from 1xto 5x. Is that the setting for HT? For some reason I OCed mine to 2.4(267x9), it will crash under 3dmark 03 and 05, but its prime95 stable. If I down clock to 2.3(256x9),everything is stable at that setting. I locked my AGP at 66Mhz any idea? Do I need more voltage on AGP? I ususally dont put more voltage on APG. Last Question, what about NB,SB, and HT voltage? Do I need to bump up abit for all of them? I usually just bump up a bit on NB voltage. Thank you all for reading, and all advices are welcome

Yes, thats it. LDT=HTT per Abit for some reason.

LDT=HTT.

Yes, locking AGP/PCI frequency (at 66/33) is a must when overclocking.

OC with everything at default voltages is usually the ideal scenario. I wouldn't touch anything besides the vmem/vdimm and vcore.
