Hi I was wondering what the usual stable oc on a hd 4870 x2 was and the core voltage. As well as what is the max I should do with out hurting my card. Any advice would be appreciated!

Using MSI Afterburner to oc

atm im using stock 800mhz core 975mhz mem

Sorry about the wait...

temps on that card can get a little high so id suggest a modest 875mhz core and a 1000mhz mem.

Safe temps are around 80'C but don't let it get above 100'C

Tops for that card would be about 1000MHZ & 1100MHZ (Water cooling would be required) Dont try pushing it over 875 with stock cooling

Good Luck:D 

Edit = I have no idea what the core voltage would be... not all cards are created equal, some need a little more juice to get themselves stable
