cjloki Posted June 10, 2009 Posted June 10, 2009 i forgot to add, my HD4850 is the gigabyte version with the zalman fan i use the 1gb overclocked version (gv-r485oc-1gh) in conjuction with my 4850x2 in a trifire arrangement and have no trouble running 700x993 on all 3 gpu's but having said that i'm unsure whether the 512 will overclock that high. you'll just have to experiment with it....maybe try the auto-tune feature in ccc overdrive....good luck with that..........cj Share this post Link to post Share on other sites More sharing options...
Reagnon Posted June 10, 2009 Posted June 10, 2009 (edited) I have that 4850 too the guaranteed speed of the card is 700mhz core clock and 993mhz memory. I got my card to 720mhz core(just for now) and 1050mhz memory. You are limited by catalyst controll center to 750 mhz core but with the software they inclued you could get higher (i am going to try that myself) or other software...
