I have that but with only one of my cards, my first 7850 clocks quite nice and will run 1.2ghz, but my second one doesnt like going past 1ghz, its stock clock is 950mhz - power edition smile.gif

its really annoying, im wondering if the bioses are different or if i just got really unlucky chip lottery results on the second card frown.gif

vcore needed and unofficial Overclocking is needed too

Both of your cards should clock better. 7 series cards are really good at overclocking. I can get a stable 1250 core and 1350 ram on stock volts. Haven't tried to go higher yet.

Make sure you have good cable management, nothing blocking or coming near the card, good case airflow. Only thing I cant think of is its slightly overheating or throttling or something.

Check power cables as well. Sorry thats about all I can think of.

Maybe run furmark and see if it handles it at stock. If it does I would just say bad chip lottery. redface.gif
