ATI 3850/3870 Voltmod thread

[Menhir]

i penciled the black marked resistor

it was 2.43 default
i penciled it to 2.22 what gave me 1.40 volt
when i pencil it to 2.19 it give me 1.44 volt

it seems a verry good ressistor for a huge voltage range

i get with my gecube 3850 turbo 3 850Mhz@1.40 volt
but i cant get 864 stable...is it the bios bug?

try overclocking the mem and see what happens

try overclocking the mem and see what happens

even at default memclock (900mhz) i get artifacts with ati tool @864Mhz

when i set the GPU to 850Mhz (there is nothing possible between 850 and 864) i get no artifacts even if the mem is clocked at 1060

i mean 850 is not bad for a 3850 but default 3870 can reach it easiely but not more because of the bios bug

did you flash the unlocked bios for the 512MB 3850

Which would I shade on my 3870?

The one circled in black or blue..?

Also, it doesn't matter whether or not a multimeter is analogue or digital does it?

Thanks
