ATI 3850/3870 Voltmod thread

[NapalmV5]

NapalmV5, sorry, I misread Your text. Ofcourse caps can give us higher OC stability. For higher Vgpu You used fixed resistor
Do You have any pics from that mod? There are 4-6 caps in PWM, am I right? You parallel-soldered some electrolytic ones or You removed the original and replaced it with higher tantalum-cap?

i didnt parallel cap/add caps.. ive tried it though.. @ diminishing results

so all i did to gain the 15mhz is i removed the 330uf cap (C730) and replaced it with a 1000uf blackgate fk cap

bam! easy 15mhz for a total of 1065mhz

Thanks mate I'll see what I can do I just did a light mod (100k pot on DDR and bumped the core volt a bit).


BTW those are remarkable scores kinking some 4050 4070 butts!

lol

the vddr mod offered only 10mhz so i removed it
