Overclocking a Factory Clocked Card

[Guest]

This is a total noob question I bet, but if I bought a Factory Clocked card, could I over clock it further?

Sure you can.

Possible, but maybe not by much more. Also if it gets too hot it would be a good idea to buy a new heatsink/fan for the video card capable of handling higher temps.

Higher overclocks are not always possible even with a new HSF and voltage increases.

Any ideas how far I could over clock one of these by -

It varies card to card but I have heard of many people hitting 1Ghz core with the 4890.
If you are lucky and have a good piece of silicon, you should be able to get quite a bit more speed out of it.
If you get a weaker chip, I would still expect it to top 900Mhz with out to much trouble.

That card seems to be like it's already overclocked at the factory. You can always try but be sure to monitor your heat temps.
