Leadtek 4200 overclocking

[Goo Kenson]

I have mine overclocked to 300 core and 531 memory. I could push it farther but I havn't tried yet, these seem like stable, safe numbers.

How high have you overclocked yours, and have you experienced any heat issues or anything? I don't have any modified cooling, just stock.

I got an Asus V4820, doesn't seem the most overclockable card in the world, I'm on 300/535 or around that, push the memory to about 550 and I get artifacts.
