i rma'ed my gpu a copule of days ago and here is my gpu-z snap...now according to nvidia the memory clock shud be about 900mhz but as u can see gpu-z shows only 500mhz.i've checked this even while gaming but the number doesn't go up which rules out the power saving feature. to reconfirm this,i also checked out the numbers in riva tuner but unfortunately its the same story. can someone help? this wasn't the case bfore the rma was done p.s. the performance doesn't seem to have taken a hit,but i'm curious.
