Hi guys please help me
I wanted to do this pencil mod on my Gigabyte Radeon HD 4850 OC 1GB. So I removed my GFX and for a about 1 hour I tried to find where to do the modding!
My card is blue not red. I figured that ATI/AMD made all the cards and all that was different was the "cooling solution" and the bios? I must be mistaking, because I cant seem to find those numbers RC85, C659, R710 shown on the pictures

so i have no clue where to do the modding. I guess GigaByte have named things differently. I really need your help it must be possible to do this volt mods on the Gigabyte Radeon HD 4850 OC 1GB as well right? ...
PS: Sorry for my bad English (grammar)
