FYI, stock specs are 900MHz for the 4870, if it can run anything above that, it's just a bonus, not a requirement.

Also FYI, when memory can't handle a certain speed, you get artifacts or lock-ups, either way, you'll bump the speed down to retain stability so no damage can be done regardless. It's VERY dfficult to kill memory unless you're increasing voltage considerably.
how does your X2 clock? can you clock the cores independently with Overdrive? is the second core a bad overclocker because of the extra heat?
