overclocking on 7870

[zxzx11]

Am i missing something my sapphire 7870 oc edition has very little overclocking headroom. Tomb raider and heaven 4.0 at 1125 1250 results to bsod. Not to mention its stock voltage is at 1.25v. However i didnt even see an artifact with furmark even at 88c. Im using seasonic 520 watts.

If everything's stable, you're fine. And sometimes that's what happens--overclocking is never guaranteed and every chip is different.

To add above, you already bought an OC'd card, so it is already pushed.

Also trying to jump from 1125 to 1250 is a huge jump. You go like 25 at a time, not 125.
