4870 Overclocking Thread

[SNiiPE_DoGG]

Thanks for sharing. To play safe I think I would use 820/1050 as it seems most cards should be able to do this with ease at 31%+ fan speed. I hope at those speeds it demolishes my currently overclocked 8800 Ultra.

I was running at 1050 and i even went down to 1000, the ramdacs are rated for 4 ghz only by spec. I will be trying the MVDDC and MVDDQ pencil voltmods for the ram as soo as I confirm that my voltmod was successful (dont have the water loop together yet so I can't plug the volt modded card in to the board)




@ strangelife, there is no 4870 pencil voltmod, only soldering. bios does not adjust voltage (tested with multimeter)
