I wanted to ask people who own the XFX 5870 ATI HD card what kind of overclocking they have gotten with the MSI Afterburner program. I currently have clocked at 1000/1300 at 1.3V with the fan locked at 50%. It seems to be stable at this setting and load temp is about 75C. So can I even push further? What is the max voltage I should not go over when overclocking. I am not sure what my boundaries are with shader clock and the memory clock. I would appreciate some more guidance. I am looking the best overclock possible with my system. Thanks guy.

Hmm well i have not been so lucky or maybe i am too scared to destroy it ;)

Mine runs smooth at 910/1300 but when i run at 920 it starts to actually slow down

What struck me the most is that speeding up the memory has little to no affect at all on my games and so on

to be honest i have not messed with the voltage since most claim to easily get it to 1000 mhz without changing this
