7850 is quite random in overclocks.
Some barely make it to 1050, some get to 1250+


To overclock you need to run gpu-tweak and up the volts to maximum around 1.225v , some cards get 1.25 to 1.3

run the fan on manual settings to see the highest speed % before it get's noisy, plot the fan profile graph with this highest manual speed kicking in around 5 to 10 celcius above your idle temperature, add 2 more gradual points in between

familiarize yourself with the gpu-tweak program such as finding the "advanced" button and "enhance overclocking range"
slide the power limit to 120%

run crysis2 (or other intensive game) at maximum settings

up the core clock by 20mhz every time you survive 20 minutes, you can add more mhz per increment if you are impatient
you will end up with the core being crysis2 stable around 1100 to 1200+ mhz, repeat the tests with memory clocks increasing by 100mhz ( 25x4 ) , you should end up around 5000 to 6000mhz memory stable

after finding out this max gaming stable overclock you can try to find out your max overclock on default voltage
