i have two retro video cards. first one is a sapphire ati radeon 8500le 64mb. please refer to the attached pics. i have close up photos of the coils showing the number of turns on them as well as a shot of the whole card so u can see the vrm design.
thing is, im not sure how many turns are on the coil? is the vrm for the gpu and video ram using high or low switching frequency? i intend to use panasonic oscon sepc 470uF 16v that i have on hand to replace the licon junk caps. one of the licon junk caps is even dented on the side!
next, is an ati radeon 9000 64mb pci. im not sure about the vrm design on this card. is that a linear regulator or a switching regulator? if its a linear, it wont like being polymodded. need to know so i can pick caps with the right esr to replace the kingcon junk caps. i already replaced the red sacon fz junk caps that originally came with the card to suncon/sanyo wg.
