Hey,
What Kind Of Specs Should I be Able To Get With AN "asus 4870" with a Zalman Heatsink.

Thanks.

if you're lucky, you should be able to hit 800-850 on core and 4200-4400 on memory. you have to try it on your own, though.

i have an 2 asus 4850's and then don't overclock well at all.. pretty much no overclock is possible.. it it because i heatsink is not covering the vrm's/memory chips? would covering those in heatsinks allow me to overclock?

i think part of the reason why i cant overclock is cuz of crossfire but im not sure.. anyone know?

I have a HIS 4870 1gig and i can get 840/850 core if it stays cool and i cant go past 1000mem and even that isn't stable 24/7. i really does depend but i would go from stock to so 825core, 975mem. Its a decent increase and also on the safe side, so long as you keep an eye on the temps.
