how bout usin lower ram divider? it could be psu juice not enuf if there's hisslin sound from mobo/psu. from my experience of oc'in am2 on 770 chipset board, u just need to play w/ cpu-nb voltage, vcore & vdimm. mebe u can pass me ya chip to play around b4 i change to 790gx board...

i tried already bro...DDR800 ratio more stable to oc

HT and ND voltage is edy too high
HT voltage should be set 1.25(stock) or 1.275
NB voltage should be set 1.5 (stock) or 1.7
i tried already from stock till 1.3v

still cannot
did u lock up the option at bios CPU-VID to 1.35 ??
yup done already

I got the same issue with my TA770 previously. Hissing like madness
But for me only way that will happen is when i oc my gc...

i think the hissing sound are cause by the nb or sb voltages.. last time i OC and add the nb and sb voltages, it alway make the hissing sound...
yahhh...u r rite casperito..mine when i add vcore or oc exceed 3.1xx that sound will come out

when i fail on orthos the sound a more worse!

like got bug inside my rig lol

is it really my psu fault? i use CM Extreme power 460W the device on my rig r : CPU | Mobo | 2 stick ram | 1 DVD-RW drive | 3 Led 120mm fan | 1 Aux Fan | 8800GT gc only...i done do the wattage calculation only use 315W

*btw can any1 recommend me what mobo r around rm300 that good to oc aye?

thx...
