Still how come a majority of the people are running far slower? This is making me not trust the wiki and makes buying hardware trickier.
majority of people don't overclock (or they doing whatever ccc let them - which is usually 5-10%)
default 6950 have 900/1250 and 1408 shaders
now, you adding 10% in shaders, 15% in gpu clock and you wonder why your hashrate is 410 instead 360?
Default 6950 is actually 800Mhz core, so he is adding 20% on top of the default freq, with the unlocked shaders.
Anyway, you need to look at the date when those entries were added, most were 3/11, the newer miners got a significant hashing boost with newer routines. Outdated entries are outdated. My 6950 unlocked at stock clocks got about 350-360MHash/sec after using the updated hashing routines.
