ATI 4850/4870 voltmod thread

[Jim M0rrison]

its the same controller like here on my gainward GS its good for up to 970 3dmark @ 1,60V

4phase delivery is great! i wouldnt change card...

find pin 19 on the datasheet and measure resistance between fbpin and ground then set 20x vr between fb and ground, finished.

Thanks for the response. I really don't want to go OT here, but its a fact that there are numerous threads on different forums where people complain about their revised version of the powercolor 1GB pcs. Even if the controller is good, can't there be cheapo inductors/resistances etc?

In any case, the card was really cheap when I bought it, so I guess Ill take my chances - I'll be modding some crazy ghetto cooling (air, ofc) and maybe that'll help my case

Could I assume the stock voltage is the same as for reference cards, when identifying the 19'th pin?

Also, anyone knowledgeble on the vmem points? (For the non-reference pcb of the Powercolor 1GB "pcs" version 2...)

Thanks!
