ATI 4850/4870 voltmod thread

[raibemunn]

Hi, i have a question regarding my old HD3850 which im now trying to put into crossfire with HD4850 i have. 3k series thread seems too old to revive for this question.
Has anyone seen horizontal (not vertical) colored lines on the screen? Havent seen those artifacts before and google isnt helping much. Also bsod follows shortly after getting to windows. Or worse i have nothing on my screen.
Has to be hardware problem. It's now in a different pc, different windows, different drivers. Maybe i should try to bake the card?

I wonder what happened to that card after moving couple thousand km, pc was packed well. No visible damage on the card, it was working well before its trip. Are those symptoms common for gpu, memory or other components failure? (im sort of hoping for latter)
