I recently purchased a Radeon 3850 and saw that the specifications were 829mhz or the memory clock but the website said it had 1400mhz. Is it really 829mhz or 1400mhz? is there also something involved? I dont know much about video cards and was hoping someone could clear things up a bit.

This is the one i purchased

GDDR3 memory works in something called double data rate. that means that it can effectively do 2 operations in 1 cycle, so the 1400Mhz is the effective number. the number that you would see in a program would be half that, 700Mhz. i'm not sure where you got that 829Mhz, unless you overclocked it.
