ATI 4850/4870 voltmod thread

[GamerBR]

For people searching for the pencil mod point for the new sapphire card,I've found it.At stock it was 1612 ohms,giving 1.24V .Setting it to 1185 gave me 1.34v.Also the points used for measuring the voltage are different,see the picure(I will use one that other user posted so I don't need to take pictures myself).I'm yet to confirm the memory points,but I'm quite sure where they are,I will post it when I get the necessary cooling for my memories(the stock one doesn't even have a heatsink attached to them).I think this card has great potential for overvolting,with the stock cooler running at 100%,at 1.34v(with no overclock),I get 65°C (GPU temperature with GPUZ) after running Atitool "scan for artifacts" for 5 minutes,and overclocked to 795mhz it gets up to 70°C.



Edit:I was able to get up to 795mhz on the gpu,more than that and some tiny artifacts started appearing on Atitool.When overclocked the voltage goes up a little bit,at stock clock it's 1.335v and overclocked it get about to 1.347v.People with the same card,please let me know your results.
