i have a 5000 black edition @ 3.2, 14x230, 1.425vcore. it will run orthos for hours at this setting. the ram is running 4x1gb 940mhz 4-4-4-10.

if i put it @ 3.2 only using multi (16x200) and ram 4x1gb 800mhz 4-4-4-10 it errors out in orthos right away.

now i know different combinations will work, like say you set it to 3.2 using all multi's between 10 and 16, some might be stable and some not, but shouldnt a 16 multi with no other overclocking be stable? maybe its gettin too much volts since im not overclocking anything else im not too concerned about it, as i would rather run at my settings than 16x200 but i was just curious. its makin me think i should go back and try all multi's to get to 3.3 and see if any can be stable.
