4870 Overclocking Thread

[Blkout]

Do you even have a 4870? What bases are you speaking on that the memory can run "far" above the stock specs? As for memory frequency not having an effect, well it does because just like any chip more speed + more volts = more heat, which means that there is more risk to kill your ram. 10% OC is a big OC, and quite likely stable OC on the ram combined with a core OC will not be achieved using stock voltages on either. Just under 1100, possibly, over that no way.

Oh as an FYI, so far I have worked with about 4-5 4870s.

No, I sold my 4870 about two weeks ago to buy a 4870x2 which I have now. I had my 4870 for just over 2 weeks with no issues running 790/1100MHz. That was looping some benchmarks overnight as well.

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.
